Description
- Pip version: 10.0.0
- Python version: 3.6.5
- Operating system: Win 7 64
Description:
Upgrading from version 9.0.3 causes pip not to work anymore with the error message:
Fatal error in launcher: Unable to create process using '""c:\program files\python36\python.exe" "C:\Program Files\Python36\Scripts\pip.exe"
The same happens with pip3.exe or pip36.exe (of course, they are identical, but using them could help to solve path conflicts).
The only way to solve the problem was to rollback to version 9.0.3. (I also tried version 9.0.1 just as a distraction :-), and it worked too ).
Of course, I tried a plethora of solutions to be able to keep version 10.0.0, then I gave up and rolled back to version 9.0.3
What I've run:
From PowerShell or DOS window:
< python -m pip install -U pip > to upgrade pip to 10.0.0. Everything went well.
< python -m pip install pip==9.0.3 > to rollback
