On Windows at least  pip stores the execution path in the executable pip exe when it is installed   Edit this file using a hex editor or WordPad  you have to save it as plain text then to retain binary data   change the path to Python with quotes and spaces like this      C  Program Files  x86  Python33 python exe    to an escaped path without spaces and quotes and pad with spaces  dots at the end should be spaces      C  Progra 2 Python33 python exe                For  C  Program Files   this path would probably be  C  Progra 1   shortened path names in DOS   Windows 3 x notation use tilde and numbers   Windows provides this alternative notation for backwards compatibility with DOS   Windows 3 x apps   Note that as this is a binary file  you should not change the file size which may break the executable  hence the padding   Save with administrator privileges  make sure it is actually saved at the target location and try again   You might also need to set the PATH variable to use the   notation for the path to pip

I have similar problem when I reinstall my python  by uninstalling python3 7 and installing python3 8  But I solved it by removing the previous version of python directory  For me it was located here      C  Users your-username AppData Local Programs Python   I deleted the folder named Python37  for previous version  and keep Python38  for updated version   This worked because python itself seems having a trouble on finding the right directory for your python scripts

This can happen if you are using a case-sensitive file system on Windows  You can tell if this is the case if there is both a lib directory and a Lib directory in your venv directory     gt  dir  Directory  C  git case sensitive filesystem here venv  Mode                LastWriteTime         Length Name ----                -------------         ------ ---- d-----        4 07 2018   4 10 PM                Include d-----       22 01 2019   7 52 AM                Lib d-----       22 01 2019   7 52 AM                lib d-----       22 01 2019   7 52 AM                Scripts d-----       22 01 2019   7 52 AM                tcl   To workaround this  until virtualenv py gets fixed  https   github com pypa virtualenv issues 935  merge the two lib directories and make venv case-insensitive   cd venv move Lib rmthis move   rmthis site-packages  lib rmdir rmthis fsutil exe file setCaseSensitiveInfo   disable

I had this issue and the other fixes on this page didn t fully solve the problem   What did solve the problem was going in to my system environment variables and looking at the PATH - I had uninstalled Python 3 but the old path to the Python 3 folder was still there   I m running only Python 2 on my PC and used Python 2 to install pip   Deleting the references to the nonexistent Python 3 folders from PATH in addition to upgrading to the latest version of pip fixed the issue
