AttributeError: Module Pip has no attribute 'main'

Question

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

Answer 1

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.

Answer 2

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

Answer 3

Pip 10.0.* doesn't support main.

You have to downgrade to pip 9.0.3.

Answer 4

It works well:

 py -m pip install --user --upgrade pip==9.0.3

Answer 5

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'])´

Answer 6

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.
