How to make sure which python version my pip packages are installed for

Question

I use macOS and therefore there is a default python 2.7 and a 3.6 which was installed by myself. I am a beginner and I am rather confused that I don’t know whether my pip packs are installed for the 2.7 or the 3.6

Many thanks!

You can install your pip packages for specific python versions. From the docs:

On Linux, Mac OS X, and other POSIX systems, use the versioned Python commands in combination with the -m switch to run the appropriate copy of pip:

# default Python 2
python2 -m pip install SomePackage

# specifically Python 2.7
python2.7 -m pip install SomePackage

# default Python 3
python3 -m pip install SomePackage

# specifically Python 3.4
python3.4 -m pip install SomePackage
