没有名为 _sqlite3 的模块

Question

I am trying to run a Django app on my VPS running Debian 5. When I run a demo app, it comes back with this error:

  File "/usr/local/lib/python2.5/site-packages/django/utils/importlib.py", line 35, in     import_module
    __import__(name)

  File "/usr/local/lib/python2.5/site-packages/django/db/backends/sqlite3/base.py", line 30, in <module>
    raise ImproperlyConfigured, "Error loading %s: %s" % (module, exc)

ImproperlyConfigured: Error loading either pysqlite2 or sqlite3 modules (tried in that     order): No module named _sqlite3

Looking at the Python install, it gives the same error:

Python 2.5.2 (r252:60911, May 12 2009, 07:46:31) 
[GCC 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sqlite3
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.5/sqlite3/__init__.py", line 24, in <module>

  File "/usr/local/lib/python2.5/sqlite3/dbapi2.py", line 27, in <module>
    from _sqlite3 import *
ImportError: No module named _sqlite3
>>>

Reading on the web, I learn that Python 2.5 should come with all the necessary SQLite wrappers included. Do I need to reinstall Python, or is there another way to get this module up and running?

Answer 1

It seems your makefile didn't include the appropriate .so file. You can correct this problem with the steps below:

1. Install sqlite-devel (or libsqlite3-dev on some Debian-based systems)
2. Re-configure and re-compiled Python with ./configure --enable-loadable-sqlite-extensions && make && sudo make install

---

Note

The sudo make install part will set that python version to be the system-wide standard, which can have unforseen consequences. If you run this command on your workstation, you'll probably want to have it installed alongside the existing python, which can be done with sudo make altinstall .

Answer 2

I had the same problem (building python2.5 from source on Ubuntu Lucid), and import sqlite3 threw this same exception. I've installed libsqlite3-dev from the package manager, recompiled python2.5, and then the import worked.

Answer 3

I had the same problem with Python 3.5 on Ubuntu while using pyenv .

If you're installing the python using pyenv , it's listed as one of the common build problems . To solve it, remove the installed python version, install the requirements (for this particular case libsqlite3-dev ), then reinstall the python version.

Answer 4

This is what I did to get it to work.

I am using pythonbrew(which is using pip) with python 2.7.5 installed.

I first did what Zubair(above) said and ran this command:

sudo apt-get install libsqlite3-dev

Then I ran this command:

pip install pysqlite

This fixed the database problem and I got confirmation of this when I ran:

python manager.py syncdb

Answer 5

1. Install the sqlite-devel package:

   yum install sqlite-devel -y

2. Recompile python from the source:

    ./configure make make altinstall

Answer 6

my python is build from source, the cause is missing options when exec configure python version：3.7.4

./configure --enable-loadable-sqlite-extensions --enable-optimizations
make
make install

fixed

Answer 7

My _sqlite3.so is in /usr/lib/python2.5/lib-dynload/_sqlite3.so. Judging from your paths, you should have the file /usr/local/lib/python2.5/lib-dynload/_sqlite3.so.

Try the following:

find /usr/local -name _sqlite3.so

If the file isn't found, something may be wrong with your Python installation. If it is, make sure the path it's installed to is in the Python path. In the Python shell,

import sys
print sys.path

In my case, /usr/lib/python2.5/lib-dynload is in the list, so it's able to find /usr/lib/python2.5/lib-dynload/_sqlite3.so.

Answer 8

I found lots of people meet this problem because the Multi-version Python, on my own vps (cent os 7 x64), I solved it in this way:

1. Find the file "_sqlite3.so"

    find / -name _sqlite3.so

   out: /usr/lib64/python2.7/lib-dynload/_sqlite3.so

2. Find the dir of python Standard library you want to use,

   for me /usr/local/lib/python3.6/lib-dynload

3. Copy the file:

    cp /usr/lib64/python2.7/lib-dynload/_sqlite3.so /usr/local/lib/python3.6/lib-dynload

Finally, everything will be ok.

Answer 9

I recently tried installing python 2.6.7 on my Ubuntu 11.04 desktop for some dev work. Came across similar problems to this thread. I mamaged to fix it by:

1. Adjusting the setup.py file to include the correct sqlite dev path. Code snippet from setup.py:

    def sqlite_incdir: sqlite_dirs_to_check = [ os.path.join(sqlite_incdir, '..', 'lib64'), os.path.join(sqlite_incdir, '..', 'lib'), os.path.join(sqlite_incdir, '..', '..', 'lib64'), os.path.join(sqlite_incdir, '..', '..', 'lib'), '/usr/lib/x86_64-linux-gnu/' ]

   With the bit that I added being '/usr/lib/x86_64-linux-gnu/'.

2. After running make I did not get any warnings saying the sqlite support was not built (ie, it built correctly :P ), but after running make install , sqlite3 still did not import with the same " ImportError: No module named _sqlite3" whe running "import sqlite3 ".

   So, the library was compiled, but not moved to the correct installation path, so I copied the .so file ( cp /usr/src/python/Python-2.6.7/build/lib.linux-x86_64-2.6/_sqlite3.so /usr/local/python-2.6.7/lib/python2.6/sqlite3/ — these are my build paths, you will probably need to adjust them to your setup).

Voila! SQLite3 support now works.

Answer 10

This worked for me in Redhat Centos 6.5:

yum install sqlite-devel
pip install pysqlite

Answer 11

sqlite3 ships with Python. I also had the same problem, I just uninstalled python3.6 and installed it again.

Uninstall existing python:

sudo apt-get remove --purge python3.6

Install python3.6:

sudo apt install build-essential checkinstall
sudo apt install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tar.xz
tar xvf Python-3.6.0.tar.xz
cd Python-3.6.0/
./configure
sudo make altinstall

Answer 12

For Python 3.7.8 with Redhat 7 or Centos 7.

• Install sqlite-devel

$ yum install sqlite-devel

• Compile and install Python3 with sqllite extensions

$ ./configure --enable-optimizations --enable-loadable-sqlite-extensions
$ make install

Answer 13

I have the problem in FreeBSD 8.1:

- No module named _sqlite3 -

It is solved by stand the port ----------

/usr/ports/databases/py-sqlite3

after this one can see:

OK ----------
'>>>' import sqlite3 -----
'>>>' sqlite3.apilevel -----
'2.0'

Answer 14

是否安装了python-pysqlite2包？

sudo apt-get install python-pysqlite2

Answer 15

Checking your settings.py file. Did you not just write "sqlite" instead of "sqlite3" for the database engine?

Answer 16

Putting answer for anyone who lands on this page searching for a solution for Windows OS:

You have to install pysqlite3 or db-sqlite3 if not already installed. you can use following to install.

• pip install pysqlite3
• pip install db-sqlite3

For me the issue was with DLL file of sqlite3.

Solution:

1. I took DLL file from sqlite site . This might vary based on your version of python installation.

2. I pasted it in the DLL directory of the env. for me it was "C:\\Anaconda\\Lib\\DLLs", but check for yours.

Answer 17

你必须在centos或redhat并且自己编译python，这是python的错误，在你的python源代码目录中执行此操作并在下面执行此操作

curl -sk https://gist.github.com/msabramo/2727063/raw/59ea097a1f4c6f114c32f7743308a061698b17fd/gistfile1.diff | patch -p1

Answer 18

I got the same problem, nothing worked for me from the above ans but now I fixed it by

just remove python.pip and sqlite3 and reinstall

1. sudo apt-get remove python.pip
2. sudo apt-get remove sqlite3

now install it again

3. sudo apt-get install python.pip
4. sudo apt-get install sqlite3

in my case while installing sqlite3 again it showed some error then I typed

5. sqlite3

on terminal to check if it was removed or not and it started unpacking it

once the sqlite3 is installed fireup terminal and write

6. sqlite3
7. database.db (to create a database)

I'm sure this will definitely help you

Answer 19

I was disappointed this issue still exist till today. As I have recently been trying to install vCD CLI on CentOS 8.1 and I was welcomed with the same error when tried to run it. The way I had to resolve it in my case is as follow:

• Install SQLite3 from scratch with the proper prefix
• Make clean my Python Installation
• Run Make install to reinstall Python

As I have been doing this to create a different blogpost about how to install vCD CLI and VMware Container Service Extension. I have end up capturing the steps I used to fix the issue and put it in a separate blog post at:

http://www.virtualizationteam.com/cloud/running-vcd-cli-fail-with-the-following-error-modulenotfounderror-no-module-named-_sqlite3.html

I hope this helpful, as while the tips above had helped me get to a solution, I had to combine few of them and modify them a bit.

Answer 20

Download sqlite3:

wget http://www.sqlite.org/2016/sqlite-autoconf-3150000.tar.gz

Follow these steps to install:

$tar xvfz sqlite-autoconf-3071502.tar.gz
$cd sqlite-autoconf-3071502
$./configure --prefix=/usr/local
$make install

Answer 21

如果您使用的是 FreeBSD，请尝试像这样安装 sqlite。

pkg install py27-sqlite3-2.7.10_6

Answer 22

I had the same problem after installing Python 3.8.11 using asdf

To fix the issue:

I had to install libsqlite3-dev

sudo apt-get install libsqlite3-dev

Then uninstall Python via asdf

asdf uninstall python 3.8.11

And install Python again via asdf

asdf install python 3.8.11

Answer 23

The following worked for Python 3.9 with a virtual environment:

Answer 24

I faced this issue with multiple python dependent package while setup in python virtual enironment in Ubuntu .It is because of sqlite binding for our python .

Error I got :

    from pysqlite2 import dbapi2 as sqlite3
ModuleNotFoundError: No module named 'pysqlite2'

I resolved it by --enable-loadable-sqlite-extensions=yes 1.) First find your python or python version you used for creating virtual env. I have used python3.8 eg

$ whereis python
python: /usr/bin/python3.6m /usr/bin/python /usr/bin/python3.8 /usr/bin/python2.7-config /usr/bin/python3.8-config  python

$ cd /usr/bin

$ls
python3.8
python3.8-config

Note: there will be many package check for pytho. you will find configure file for each python version, now use specific python version

ox:/usr/bin$ ./python3.8-config --enable-loadable-sqlite-extensions=yes

OR

ox:/usr/bin$ ./python3.8-config --enable-optimizations --enable-loadable-sqlite-extensions

Now, create your virtual env using that python version eg Go the folder where you want to create the virtual env

$ python3.8 -m venv mlwen_jup_env
$ source mlwen_jup_env/bin/activate

Its done, now you can install packages

Answer 25

I ran into this same problem on a NetBSD server. A missing .so file needed to be installed using pkgin . To identify what package to install, I ran

pkgin search sqlite

which had lots of results, including

...

py38-aiosqlite-0.17.0nb1  Async bridge to the standard sqlite3 module
py38-apsw-3.37.0nb2  Python wrapper for SQLite
py38-peewee-3.15.0   Small, expressive ORM for PostgreSQL, MySQL and SQLite
py38-sqlite3-3.8.13nb22  Built-in sqlite support for Python 2.5 and up
py39-aiosqlite-0.17.0nb1  Async bridge to the standard sqlite3 module
py39-apsw-3.37.0nb2  Python wrapper for SQLite
py39-peewee-3.15.0   Small, expressive ORM for PostgreSQL, MySQL and SQLite
py39-sqlite3-3.9.13nb22  Built-in sqlite support for Python 2.5 and up
...

(and other python versions as well). I'm using python 3.9, so py39-sqlite3-3.9.13nb22 was the correct choice in my case. Running

sudo pkgin install py39-sqlite3-3.9.13nb22

fixed the issue for me.

Answer 26

你需要在你的python环境中安装pysqlite ：

    $ pip install pysqlite

Answer 27

Try copying _sqlite3.so so that Python can find it.

It should be as simple as:

cp /usr/lib64/python2.6/lib-dynload/_sqlite3.so /usr/local/lib/python2.7/

Trust me, try it.
