Check commands in the PATH

[rickyegeland]

Some users have reported not being able to find the opsep etc commands after doing a pip install. Report from SPREADfAST developer:

I am trying to run this command in a Linux terminal window:

opsep --StartDate 2017-09-06 --EndDate 2017-09-06 --Experiment user --ModelName SPREAdFAST --UserFile model/fluxData_f32_170906_01 --FluxType integral --Threshold "30,1;50,1" --JSONType model --showplot --saveplot

But I get this error:

opsep: command not found

Check how pip commands make way to the PATH, and whether they are immediately available in the pip install terminal session.

This question has the right answer, I think:

Users can find where their pip install directory is with python3 -m site --user-base. Append /bin to that and add that to the PATH in the shell rc. e.g. for bash:

echo "export PATH=\"`python3 -m site --user-base`/bin:\$PATH\"" >> ~/.bashrc
source ~/.bashrc

We can resolve this issue by testing this solution and writing good instructions in the README.
