Answer 1

As with any other python script, you may specify the python installation you'd like to run it with. You may put this in your shell profile to save the alias. The $1 refers to the first argument you pass to the script.

# PYTHON3 PIP INSTALL V2
alias pip_install3="python3 -m $(which pip) install $1"

Answer 2

You can use this syntax

python_version -m pip install your_package

For example. If you're running python3.5, you named it as "python3", and want to install numpy package

python3 -m pip install numpy

Answer 3

Alternatively, if you want to install specific version of the package with the specific version of python, this is the way

sudo python2.7 -m pip install pyudev=0.16

if the "=" doesnt work, use ==

x@ubuntuserv:~$ sudo python2.7 -m pip install pyudev=0.16

Invalid requirement: 'pyudev=0.16' = is not a valid operator. Did you mean == ?

x@ubuntuserv:~$ sudo python2.7 -m pip install pyudev==0.16

works fine

Answer 4

Python 2

sudo pip2 install johnbonjovi

sudo pip3 install johnbonjovi

Answer 5

Have tried this on a Windows machine and it works

If you wanna install opencv for python version 3.7, heres how you do it!

py -3.7 -m pip install opencv-python

Answer 6

I had Python 2.7 installed via chocolatey on Windows and found pip2.7.exe in C:\tools\python2\Scripts.

Using this executable instead of the pip command installed the correct module for me (requests for Python 2.7).
