Install psycopg2 on Ubuntu

Question

I'm trying to get the python postgres client module installed on Ubuntu 12.04. The guidance is to do the following:

apt-get install python-psycopg2

However, apt says that the package can't be located.
I'm keen to install this through apt . Is this part of another package that I can install?

Answer 1

This works for me in Ubuntu 12.04 and 15.10

if pip not installed:

sudo apt-get install python-pip

and then:

sudo apt-get update
sudo apt-get install libpq-dev python-dev
sudo pip install psycopg2

Answer 2

Using Ubuntu 12.04 it appears to work fine for me:

jon@minerva:~$ sudo apt-get install python-psycopg2
[sudo] password for jon:

What error are you getting exactly? - double check you've spelt psycopg right - that's quite often a gotcha... and it never hurts to run an apt-get update to make sure your repo. is up to date.

Answer 3

Use

sudo apt-get install python3-psycopg2

for Python3 )

Answer 4

这对我有用：

pip install psycopg2-binary

Answer 5

我更新了我的requirements.txt以具有psycopg2==2.7.4 --no-binary=psycopg2以便它在源代码上构建二进制文件

Answer 6

According to the official documentation https://www.psycopg.org/install/

sudo apt install python3-dev libpq-dev
pip install psycopg2

Answer 7

如果您使用的是 virtualenv，我更喜欢使用 pip：

1. apt install libpython2.7 libpython2.7-dev
2. pip install psycopg2

Answer 8

You should install the library using pip, but this requires multiple system dependencies:

sudo apt-get install libpq-dev python3-dev

Then you can run

pip install psycopg2

---

Debugging

If you are missing libpq-dev, you will get the error:

Error: pg_config executable not found.

If you are missing python3-dev, you will get the error:

fatal error: Python.h: No such file or directory
