About python pip installation (pip install pyswmm) error

See my comment in another thread earlier today:

Calculate Area Under Curve Given a Set of Coordinates

You don’t need to install the csv module, it is a standard module that comes pre-installed with Python. pip is not a Python module as such (well, it kinda is, but let’s not get bogged down in technicalities). It is an application (“app”) or tool that is written in Python, but you have to call it from your operating system’s command prompt, not the Python interpreter. You don’t use pip from inside the Python interpreter: if you see the >>> prompt, you are inside the interpreter, also called t…

You don’t run pip from inside the Python environment. You need to run it from the Windows command prompt.

Because you have two versions of Python on your system, it is important that you use the py -m pip ... version of the command, otherwise you may get confusion over which Python gets the packages installed.

I’m not sure how it works on Windows, but if pip still doesn’t work, you may need to run py -m ensurepip first to set it up. The documentation says you won’t need to run it, but who knows?

1. Make sure you are running from cmd.com and not the Python interpreter, if you see the >>> prompt you are in Python.
2. Try using py -m pip install PackageName (for whatever package you are trying to install).
3. If and only if that reports an error “No module named pip” should you then try py -m ensurepip.

Good luck!
