I am new to Python and therefore I am struggling to resolve the following problem. I installed pip and I made a user installation of pipenv and then on my project folder I run the command: 

pipenv install requests

which gives me an error saying that the pipenv command either wrong or cannot be found.

I added following path on my system environment variables the :

C:\Users\andri\AppData\Roaming\Python\Python37\Scripts

but still it does not work. Does anyone have an idea as to what I should do next in order to fix this? Thanks in advance

UPDATE:

My operating system is Windows.

Here is how I installed pip through cmd


C:\Users\andri>python -m pip install -U pip

  • Did you install it through? Sudo ? It happens sometimes because it needs to be installed that way so it would be sudo pip install pipenv or if that doesn't work try this one sudo -H pip install -U pipenv . Also do you have virtualenv or another virtual environment the two could be conflicting. – smitty_werbenjagermanjensen Mar 18 '19 at 12:49
  • hey thanks for the answer! I am using windows, is the sudo command still gonna work here? I get an error – ffblord Mar 18 '19 at 12:55
  • Please include [the exact command(s) you are running, and the exact output, from a "clean state", and environment details where applicable](/help/mcve). E.g. any virtualenvs involved? What OS? How did you install `pip` and `pipenv`? – ivan_pozdeev Mar 18 '19 at 12:56
  • One more: where is your Python installation and is it on `PATH`? – ivan_pozdeev Mar 18 '19 at 13:00
  • So after you installed pipenv you tried pipenv install requests.... What is the output of the following: pipenv --python 3.7 . Also have you checked the GitHub for pipenv it is linked https://github.com/pypa/pipenv – smitty_werbenjagermanjensen Mar 18 '19 at 20:29

pip is actually helpfully warning you about this situation right there...

The script virtualenv-clone.exe is installed in 'C:\Users\andri\AppData\Roaming\Python\Python37\Scripts' which is not on PATH. Consider adding this directory to PATH... The script virtualenv.exe is installed in 'C:\Users\andri\AppData\Roaming\Python\Python37\Scripts' which is not on PATH. Consider adding this directory to PATH... The scripts pipenv-resolver.exe and pipenv.exe are installed in 'C:\Users\andri\AppData\Roaming\Python\Python37\Scripts' which is not on PATH. Consider adding this directory to PATH...

You will need to add that directory

C:\Users\andri\AppData\Roaming\Python\Python37\Scripts

to your PATH environment variable; there are many ways to do it, see e.g. Adding directory to PATH Environment Variable in Windows

Another option is to just always use

C:\...> C:\Users\andri\AppData\Roaming\Python\Python37\Scripts\pipenv install

but I think that might get a little stale quickly.

  • Thanks for the answer! As I have written on my question, I have already done this step. Hence, the path is already added on the variables – ffblord Mar 18 '19 at 13:07

    Try opening a new Command Prompt then. Sometimes path changes don't get directly applied. – AKX Mar 18 '19 at 13:09

There is your answer. The Scripts directory with utility scripts for packages installed per-user is not on PATH, so your command shell won't find them unless you add it.

If you have just added it to PATH via the Control Panel, see windows - Why are changes to my PATH not being recognised? - Super User
