installing python packages have issue in md5

问题

I'm using Windows and when I want Install packages I got below error:

pip install django
Requirement already satisfied (use --upgrade to upgrade): django in c:\python27\lib\site-packages

C:\code\Djangotest\amar-e-simples-master>pip install django --upgrade
Collecting django

             Got        f603e16057383b3ad12d8bda84492fbb

what to do with this problem (In windows)?

回答1:

If you get an error like pip: error: no such option: --hash, you are using too old a version of Pip, use the following command to upgrade:

$ pip install --upgrade pip

On Windows the recommended command is:

python -m pip install --upgrade pip

After the update, if the this error appeared again, use "--no-cache-dir" when you upgrade/install:

pip --no-cache-dir install YOUR-PACKAGENAME

pip --no-cache-dir install --upgrade YOUR-PACKAGENAME

A good reason for the hash to be different is if you use a platform that isn’t covered by the existing hashes for a package that has wheels.
