I recently upgraded pip to version 20.1 and now whenever I try pup install
on my PC I get the following error :- Fatal error in launcher : unable to
create process using '"c:\python38\python.exe '
"c:\Python38\Scripts\pip.exe" : The system cannot find the file specified.
But when I manually inspected the folder 📂 the files were there I even
tried upgrading it by python -m pip install --upgrade pip which worked but
I still can not use pip.


Just thoughtI'd try it on my Windows PC ...

Which all means there are problems with pip on Windows if you don't 
follow the documented advice very carefully. The reason is that Windows 
is not designed for developers and pip has to turn itself inside out for 
Windows compared with Linux pip.



Just in case you didn't notice, I did all the above in a virtualenv. 
Here is the base Python pip ...


C:\Python36>python.exe -m pip install --upgrade pip

So I had better install six ... but to use the correct pip and python I 
need to be specific ...

I have to use Python36 because that is the version supplied in Ubuntu 
18.04 which I use for our production server.



It does work and you should understand that Microsoft does not go out of 
its way to make things easy for anyone who doesn't do things their way.
