pyinstaller not found when freeze

[JiaEnChua]

I have pip install all the requirements and even pip install pyinstaller alone one more time just to make sure it is installed.
I did python3.5 -m pip install pyinstaller, it gives:

Requirement already satisfied: pyinstaller in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages (3.3.1) Requirement already satisfied: setuptools in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages (from pyinstaller) (20.10.1) Requirement already satisfied: pefile>=2017.8.1 in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages (from pyinstaller) (2017.11.5) Requirement already satisfied: macholib>=1.8 in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages (from pyinstaller) (1.9) Requirement already satisfied: future in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages (from pefile>=2017.8.1->pyinstaller) (0.16.0) Requirement already satisfied: altgraph>=0.15 in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages (from macholib>=1.8->pyinstaller) (0.15)

but when I do python3.5 -m fbs freeze
it raised the following error:

Do you get an error when you just type pyinstaller into a Terminal?

The error you posted seems to me like you are not using a virtual environment. Is that correct? If yes, please try again with the virtual environment:

git clone https://github.com/mherrmann/fbs-tutorial.git
cd fbs-tutorial
python3.5 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
python -m fbs freeze

Hope this helps.

(You may have to replace pip and python in the above by pip3 or python3 or python3.5.)

Thanks for your response but it prompted another issue which I am not sure how to deal with

[mherrmann]

This is unrelated to fbs. Please consult Google/Stackoverflow to find a solution. Sorry, but I don't have time to be of more help.

@JiaEnChua the pip install error may be because you are on an old pip version. Make sure you are on the latest one.

I had lots of similar cert/ssl errors with Travis CI and a "python get-pip.py" fixed it all.
