No module named 'pymysql'

Question

I'm trying to use PyMySQL on Ubuntu.

I've installed pymysql using both pip and pip3 but every time I use import pymysql , it returns ImportError: No module named 'pymysql'

I'm using Ubuntu 15.10 64-bit and Python 3.5.

The same.py works on Windows with Python 3.5, but not on Ubuntu.

Answer 1

已经在评论中回答了这个问题，但是这个问题有一个答案，问题是通过运行解决的：

sudo apt-get install python3-pymysql

Answer 2

Use:

import pymysql

Not:

import PyMySQL

That works for me.

Answer 3

After trying a few things, and coming across PyMySQL Github , this worked:

sudo pip install PyMySQL

And to import use:

import pymysql

Answer 4

If even sudo apt-get install python3-pymysql does not work for you try this:

• Go to the PyMySQL page and download the zip file.
• Then, via the terminal, cd to your Downloads folder and extract the folder
• cd into the newly extracted folder
• Install the setup.py file with: sudo python3 setup.py install

Answer 5

1. Make sure that you're working with the version of Python that think you are. Within Python run import sys and print(sys.version) .

2. Select the correct package manager to install pymysql with:

   • For Python 2.x sudo pip install pymysql .
   • For Python 3.x sudo pip3 install pymysql .
   • For either running on Anaconda: sudo conda install pymysql .
   • If that didn't work try APT: sudo apt-get install pymysql .

3. If all else fails, install the package directly:

   • Go to the PyMySQL page and download the zip file.
   • Then, via the terminal, cd to your Downloads folder and extract the folder.
   • cd into the newly extracted folder.
   • Install the setup.py file with: sudo python3 setup.py install .

Answer 6

To get around the problem, find out where pymysql is installed.

If for example it is installed in /usr/lib/python3.7/site-packages , add the following code above the import pymysql command:

import sys
sys.path.insert(0,"/usr/lib/python3.7/site-packages")
import pymysql

This ensures that your Python program can find where pymysql is installed.

Answer 7

fwiw，对于 conda env ：

 conda install -c anaconda pymysql 

Answer 8

For windows or one using google colab, you can try this

!pip install pymysql
import pymysql

Answer 9

sudo apt-get install python3-pymysql

This command also works for me to install the package required for Flask app to tun on ubuntu 16x with WISG module on APACHE2 server.

BY default on WSGI uses python 3 installation of UBUNTU.

Anaconda custom installation won't work.

Answer 10

I had this same problem just now, and found the reason was my editor (Visual Studio Code) was running against the wrong instance of python; I had it set to run again python bundled with tensorflow, I changed it to my Anaconda python and it worked.

Answer 11

I ran into the same problem earlier, but solved it in a way slightly different from what we have here. So, I thought I'd add my way as well. Hopefully, it will help someone!

sudo apt-get install mysql-client didn't work for me. However, I have Homebrew already installed. So, instead, I tried:

brew install mysql-client

Now, I don't get the error any more.

Answer 12

Just a note: for Anaconda install packages command:

1. python setup.py install

Answer 13

如果您使用的是 SPYDER IDE，只需尝试重新启动控制台或重新启动 IDE，它就可以工作

Answer 14

I also got this error recently when using Anaconda on a Mac machine.

Here is what I found:

1. After running python3 -m pip install PyMySql, pymysql module is under /Library/Python/3.7/site-packages
2. Anaconda wants this module to be under /opt/anaconda3/lib/python3.8/site-packages

Therefore, after copying pymysql module to the designated path, it runs correctly.

Answer 15

I tried installing pymysql on command prompt by typing

pip install pymysql

But it still dont work on my case, so I decided to try using the terminal IDE and it works.

Answer 16

Another common issue causing the error message to appear is related to conda environments in jupyter notebook and jupyter lab .

After successfully installing a module ( pymysql in this case) in one environment, import may seem to fail because the environment has not been correctly registered. To solve this it is necessary to manually add kernels for each environment.

Answer 20

For anaconda user,

I got this error message. ModuleNotFoundError: No module named 'pymysql'

So tried 'pip install pymysql' but got below. Requirement already satisfied: pymysql

What worked for me is,

python file.py (NOT py file.py)
