If none of the solutions mentioned above work  it can be due to environment variables pointing to two different locations   Just use where virtualenv to find the paths that are linked to virtualenv command   Run the following in cmd   D   gt where virtualenv   The output will look like   C  Program Files Python37 Scripts virtualenv exe  C  Users username AppData Local Programs Python Python36 Scripts virtualenv exe  You can see there is conflicting installation of python36 and python37  I just deleted python37 folder and the conflict was resolved

All the above answers are of great technical help  Recently I also faced the same issue due to a blunder I did with my project    I created venv inside my project root by issuing the command python -m venv   and then for some reason I didn t like the name of my project  So I changed it and boom    pip started behaving erratically and I searched dozens of forums thinking some corrupt file had crept inside my python installation  I didn t find any solution there that could help me  Finally  I opened my activate bat file to know how this script was changing my environment and there I saw the old project name mentioned  Eureka   I reverted back to my old project name and everything became smooth  Without any reinstallation  Without any change request to office admin  Without any delay   SOLUTION  If you have changed the name of your project after creating your venv  you might face this error  Reverting the new name into the old name will save your time and effort  Also please don t forget to upvote if this answer helped

Check your Windows PATH environment variable  It has a limit of 260 characters and your python location might be past that character limit   You can either move your Python paths higher in the path list or disable the Windows character limit as described here  https   msdn microsoft com en-us library windows desktop aa365247 v vs 85  aspx     A registry key allows you to enable or disable the new long path behavior  To enable long path behavior set the registry key at HKLM SYSTEM CurrentControlSet Control FileSystem LongPathsEnabled  Type  REG DWORD   The key s value will be cached by the system  per process  after the first call to an affected Win32 file or directory function  list follows   The registry key will not be reloaded during the lifetime of the process  In order for all apps on the system to recognize the value of the key  a reboot might be required because some processes may have started before the key was set       The registry key can also be controlled via Group Policy at Computer Configuration   Administrative Templates   System   Filesystem   Enable NTFS long paths
