I have two versions of python installed on my computer (3.6 and 3.7). Just upgraded pip to the latest version (19.0.1) using the command python -m pip install --upgrade pip however i think it only upgraded the pip for python version 3.6. When attempting to install a package specifically for python version 3.7 with the following command pip3.7 install scipy i got the message saying You are using pip version 18.1, however version 19.0.1 is available. Clearly only the pip for version 3.6 was upgraded. I cannot figure out a command to upgrade 3.7 pip as well. I tried the following:

python -m pip3.7 install --upgrade pip

This did not work (Trying to use the logic of how packages are handled for different versions of python). Could not find a question that addressed this specific issue. Any help would be greatly appreciated.

Use the python 3.7 interpreter to run the command:

python3.7 -m pip install --upgrade pip

Or use the pip3.7 binary directly:

pip3.7 install --upgrade pip

    Yes, if python3.7 is not on your PATH, you will need to use the full path to the interpreter, something like `/usr/local/bin/python3.7 -m pip install --upgrade pip`. – Marcus Jan 28 '19 at 20:26

I ran into the same problem. If you have Microsoft Visual also installed the best command to use is

    py -m pip install --upgrade pip --user

I used that command, and it worked like a charm.

  • In this case, one needs to add the option to select the Python version that should be used, such as `py -3.6 -m pip install ...` or `py -3.7 -m pip install ...`. Also it probably should read _Microsoft Windows_ (instead of _Visual_). – sinoroc Oct 30 '19 at 11:15
