How do I install a pip package globally instead of locally

Question

I am trying to install flake8 package using pip3 and it seems that it refuses to install because is already installed in one local location    How can I force it to install globally  system level    pip3 install flake8 Requirement already satisfied  use --upgrade to upgrade   flake8 in    local lib python3 4 site-packages   Please note that I would prefer a generic solution  that should work on Debian  OS X maybe even Windows   one that should be used on any platform so I don t want to specify the destination myself   For some weird reason it behaves like I already specified --user which in my case I didn t   The only way I was able to install a package globally was to first remove it and install it again after this  Somehow it seems that pip  8 1 1  refuses to install a package globally if it exists locally   Disclaimer  No virtual environments were used or harmed during the experiments

Where does pip installations happen in python?

I will give a windows solution which I was facing and took a while to solve.

First of all, in windows (I will be taking Windows as the OS here), if you do pip install <package_name>, it will be by default installed globally (if you have not activated a virtual enviroment). Once you activate a virtual enviroment and you are inside it, all pip installations will be inside that virtual enviroment.

pip is installing the said packages but not I cannot use them?

For this pip might be giving you a warning that the pip executables like pip3.exe, pip.exe are not on your path variable. For this you might add this path ( usually - C:\Users\<your_username>\AppData\Roaming\Programs\Python\ ) to your enviromental variables. After this restart your cmd, and now try to use your installed python package. It should work now.

Why don t you try sudo with the H flag  This should do the trick   sudo -H pip install flake8   A regular sudo pip install flake8 will try to use your own home directory  The -H instructs it to use the system s home directory  More info at https   stackoverflow com a 43623102

I actually don   t see your issue  Globally is any package which is in your python3 path   s site package folder   If you want to use it just locally then you must configure a virtualenv and reinstall the packages with an activated virtual environment

Maybe --force-reinstall would work  otherwise --ignore-installed should do the trick

Are you using virtualenv  If yes  deactivate the virtualenv  If you are not using  it is already installed widely  system level   Try to upgrade package   pip install flake8 --upgrade
