pyinstaller No module named pyinstaller

Question

I have 2 python versions installed under my mac osx sierra: python 3.5 python 2.7

I installed pyinstaller under python3.5 with this command:

python3         


        

Answer 1

I had the same problem, turns out module names are CASE-SENSITIVE which I didn't know, so instead of cmd -

python3.5 -m pyinstaller mypython35script.py

you're supposed to run

python3.5 -m PyInstaller mypython35script.py

Turns out there was no issue with Installation as it showed

Requirement already satisfied: pyinstaller in ./lib/python3.5/site-packages Requirement already satisfied: setuptools in ./lib/python3.5/site-packages (from pyinstaller)

pip install searches for the module name in PyPi (Python Package Index) where case doesn't matter

Please feel free to correct me or add comments as I am fairly new to Python and command line
