I am getting above error in command line of mac for pipenv install django=~3.1.0

>Solution :

The actual command should be :

 pipenv install django~=3.1.0

you are using =~ instead of ~= on the pip

so it should be django~=3.1.0

if the following django versions exist, it would choose 3.1.0:
else it will use the version found.

For clarification, each valid pair is equivalent that can be used

~= 3.1.0
>= 3.1.0, == 3.1.*
~= 3.1
>= 3.1, == 0.*
