AttributeError: Module Pip has no attribute 'main'
PythonPipPython Problem Overview
I am trying to build the python api for an open source project called Zulip and I keep running into the same issue as indicated by the screenshot below.
I am running python3 and my pip version is 10.0.0. The file in question is setup.py
and the code that is messing up is when the pip.main()
attribute is accessed to install a package.
Now, I know this build should succeed because its an open source project, but I have been trying for hours to fix the dependency issue regarding pip.main()
.
Any help would be greatly appreciated.
Python Solutions
Solution 1 - Python
python3 -m pip install --user --upgrade pip==9.0.3
Solution 2 - Python
It appears that pip did a refactor and moved main to internal. There is a comprehensive discussion about it here: https://github.com/pypa/pip/issues/5240
A workaround for me was to change
import pip
pip.main(...)
to
from pip._internal import main
main(...)
I recommend reading through the discussion, I'm not sure this is the best approach, but it worked for my purposes.
Solution 3 - Python
First run
import pip
pip.__version__
If the result is '10.0.0', then it means that you installed pip successfully
since pip 10.0.0 doesn't support pip.main() any more, you may find this helpful

Use something like
import subprocess
subprocess.check_call(["python", '-m', 'pip', 'install', 'pkg']) # install pkg
subprocess.check_call(["python", '-m', 'pip', 'install',"--upgrade", 'pkg']) # upgrade pkg
Edit: pip 10.0.1 still doesn't support main
You can choose to DOWNGRADE your pip version via following command:
python -m pip install --upgrade pip==9.0.3
Solution 4 - Python
This helps me, https://pip.pypa.io/en/stable/installing/
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
If you are using python3 and not set it default. do this,
python3 get-pip.py
It works for me.
Solution 5 - Python
My solution is to check the version number of pip and use the import the correct main function correctly
import pip
if int(pip.__version__.split('.')[0])>9:
from pip._internal import main
else:
from pip import main
def install(package):
main(['install', package])
Solution 6 - Python
To verify whether is your pip
installation problem, try using easy_install
to install an earlier version of pip:
easy_install pip==9.0.1
If this succeed, pip
should be working now. Then you can go ahead to install any other version of pip
you want with:
pip install pip==10....
Or you can just stay with version 9.0.1
, as your project requires version >= 9.0.
Try building your project again.
Solution 7 - Python
If python -m pip install --upgrade pip==9.0.3
doesn't work, and you're using Windows,
- Navigate to this directory and move the pip folders elsewhere.
-
Close your IDE if you have it open.
-
Press 'Repair' on Python 3.
Solution 8 - Python
Pip 10.0.* doesn't support main.
You have to downgrade to pip 9.0.3.
Solution 9 - Python
Try this command.
python -m pip install --user pip==9.0.1
Solution 10 - Python
It works well:
py -m pip install --user --upgrade pip==9.0.3
Solution 11 - Python
Edit file: C:\Users\kpate\hw6\python-zulip-api\zulip_bots\setup.py in line 108
to
rcode = pip.main(['install', '-r', req_path, '--quiet'])
do
rcode = getattr(pip, '_main', pip.main)(['install', '-r', req_path, '--quiet'])´
Solution 12 - Python
Not sure about Windows. But for mac users, use this:
pip install --upgrade pip==9.0.3
Solution 13 - Python
I fixed this problem upgrading to latest version
sudo pip install --upgrade pip
My version: pip 18.1 from /Library/Python/2.7/site-packages/pip (python 2.7)
Solution 14 - Python
I faced the same error while using pip on anaconda3 4.4.0 (python 3.6) on windows.
I fixed the problem by the following command:
easy_install pip==18.* ### installing the latest version pip
Or if lower version pip required, mention the same in the command.
Or you can try installing the lower version and then upgrading the same to latest version as follow:
easy_install pip==9.0.1
easy_install --upgrade pip
Solution 15 - Python
For me this issue occured when I was running python while within my site-packages folder. If I ran it anywhere else, it was no longer an issue.
