django.core.exceptions.ImproperlyConfigured: Error loading psycopg module: No module named psycopg
PythonDjangoModulePsycopg2Django manage.pyPython Problem Overview
Presently, I'm attempting to configure Django for use on a project, and am encountering a persistent error when I try to run python manage.py syncdb
.
File "/x/x/x/x/x/x/base.py", line 23, in ?
raise ImproperlyConfigured("Error loading psycopg module: %s" % e)
django.core.exceptions.ImproperlyConfigured: Error loading psycopg module: No module named psycopg
The other discussions of a similar problem that I have found both here and on other sites ended up being solved by the user downloading and installing psycopg, but unless I'm missing something critical, I've done that several times. I downloaded the tarball, unpacked it on my server, ran python setup.py build
and python setup.py install
with a --prefix directing it to my existing Python Path...I can go and navigate to the folder and see the various psycopg files, but for whatever reason, when I try to get my new project to sync up with the database, it cannot find psycopg and, as a result, won't talk to the db.
Notes: hostmonster.com account, have tried multiple release versions of psycopg2.
Python Solutions
Solution 1 - Python
I had the error as well; although psycopg2
was installed on my system using apt-get
, my virtualenv couldn't find it:
>>> import psycopg2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named psycopg2
It was fixed by doing a pip install psycopg2-binary
inside the virtualenv (or pip install psycopg2
for <2.8 psycopg2 versions).
Solution 2 - Python
I had this problem on a virtualenv
in Ubuntu 18.4.
I solved it by installing psycopg2 v2.7.4:
pip install psycopg2==2.7.4
Solution 3 - Python
type pip install psycopg2-binary
inside the virtualenv worked for me
Solution 4 - Python
Try to use this:
sudo apt-get install python-psycopg2
Solution 5 - Python
On MacOS, psycopgy2 v2.8.4 and its binary isn't compatible with python 3.8 yet.
Downgrade to python 3.7. All works.
1- On mac (outside venv), Uninstall 3.8 and then install 3.7 using instructions: https://www.youtube.com/watch?v=X2VXCEfIgC0
2- Go to your django project main folder, delete 'venv' folder and 'manage.py'
3- Install new venv using python 3.7. command: python3 -m venv ./venv
4- Run venv. Command: source ./venv/bin/activate
5- Install django in this new venv again. Command: pip3 install django
This will create 'django-admin' under ./venv/bin/ and the django libraries.
6- Create manage.py like you would do for a new project again. Command: django-admin startproject <project folder> .
(notice the '.' in end)
The command wont run as previous
7-Run: pip3 install psycopg2
and: pip3 install psycopg2-binary
(If you get an error pg_config executable not found error then run under venv, run following command before installing psycopg again:
export PATH=“/Applications/Postgres.app/Contents/Versions/latest/bin:$PATH)
Solution 6 - Python
You try to load psycopg, not psycopg2. Make sure that ENGINE is set to django.db.backends.postgresql_psycopg2 in the settings.py of your project:
'ENGINE': 'django.db.backends.postgresql_psycopg2'
May be problem is: 32bit version of Python cannot load a 64bit version of psycopg2.
Solution 7 - Python
I had this problem inside a python virtual environment (virtualenv), copying the library into the site-package of the environment from the system site packages solved the problem.
Solution 8 - Python
I was also receiving similar error, it simply means that it is unable to find the "psycopg2" package/module. I resolved it simply by installing it in my environment using the command:
pip install psycopg2
Solution 9 - Python
I hope this command will solve your problem (tested on ubuntu)
pip install psycopg2-binary
Solution 10 - Python
ERROR: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/usr/local/lib/python3.7/dist-packages/psycopg2'
Consider using the --user
option or check the permissions.
if the above error shows then, please try installing with:
pip install psycopg2-binary --user
Then it finally works. There is no need to edit on DATABASE ENGINE.
Solution 11 - Python
python -m pip install psycopg2
Solution 12 - Python
Run the below command in Command Line Prompt
pip install psycopg2
This will install psycopg2 and resolve the issue.
Solution 13 - Python
First:
pip uninstall psycopg2
Then, load the direct file from http://www.stickpeople.com/projects/python/win-psycopg/
file name : = psycopg2-2.6.2.win-amd64-py2.7-pg9.5.3-release.exe
As per your requirement, and then copy this downloaded file to env folder and do this:
easy_install psycopg2-2.6.2.win-amd64-py2.7-pg9.5.3-release.exe(your file name)
This will copy required files.
Solution 14 - Python
It can happen if you don't have psycopg2
installed already.
I had this problem with the virtualenv, I simply installed psycopg2
and it is working fine. No need to edit the db configurations.
pip install psycopg2
Solution 15 - Python
This Problem can be of any reason -
-
You have downloaded the wrong version of pyscog2 that doesn't support the current version of the Django.
-
You might have placed the pyscopg2 in the wrong directory.
-
You might have downloaded the pyscopg2 without the virtual environment and then activated post-install so it may be showing error.
-
Bad configuration of the virtual environment in manage.py leads to the error.
-
See the proper configuration it may be taking pyscopg2 from the root folder rather than the virtual environment.
