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

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

what to do with this problem (In windows)?

Answer 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

or

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.
