Might be npip install command?

Hi @frankTurtle,
Thank you for opening the issue and letting us know.

During the plugin download, we install our core PureSec CLI which is written in python.

To support environments with both python 3 and python 2 we execute python3 command. It seems that either python 3 binary is called python.exe or you need to add your python directory path to the PATH environment variable.

This thread should be helpul in solving this issue: how-to-switch-between-python-2-7-to-python-3-from-command-line

Please let me know if it helped.

Hey @avish9

Thanks for the quick reply!

The python directory is in the PATH env already, unfortunately. I've never had python 2.x installed either, so there would be no issues with switching between the two.

Thanks!

Hi @frankTurtle ,

Did you manage to get it working?

I ran into the same issue when attempting an install on Mac OS 10.13.5.
which python returned /usr/bin/python, and which python3 returned nothing.
I downloaded and installed python 3 from https://www.python.org/downloads/mac-osx/, and now which python3 returns /usr/local/bin/python3, and npm install --save-dev serverless-puresec-cli completes successfully.

@mrweir - thanks for the input!

@avish9 shouldn't this be included in the documentation?

I had to copy/rename python.exe to python3.exe but now I'm getting:
ERROR: Could not install packages due to an EnvironmentError: [WinError 206] The filename or extension is too long: '<redacted>\\node_modules\\serverless-puresec-cli\\python_modules\\Python38\\site-packages\\puresec_cli\\resources\\node_modules\\app-module-path\\test\\node_modules\\installed-module-allowed-explicit\\installed-module-allowed-explicit-foo'
and install fails.

Edit: this was resolved by enabling 'long paths' in win registry: https://stackoverflow.com/a/46489473
Edit 2: long paths setting seems to mess up my nginx install... (side note...)
But now I'm stuck on #17
