Script Step to run pip (python 3)

[ferPrieto]

I've got a workflow where I added a Brew install Step to install Python, which works well.

The next Step that runs after this is a Script Step that I use to run pip (one of the Python tools), in order to install a public plugin.
It contains something like this (I've added a generic name for the plugin, myPlugin):

python3 -m pip --version
python3 -m ensurepip --default-pip 
alias pip='pip3'
pip install myPlugin

The problem is that it always fails saying that it doesn't know what pip is (in the 4th line).
Surprisingly, if I run the workflow with Remote Access and I use the terminal to run the same commands it works. So I'm not sure what the issue is that is causing the pip command not being recognised.

Is this an issue known when it comes to work with Python and the package manager pip?

Hey Fernando, have you tried skipping the alias and just calling pip3 directly? I know this is not optimal, but it could help me better understand the problem better if this works.
I should also note that pip3 is already installed on the system.

Hey @matrangam I tried that already and didn't work.
When pip3 tries to install any package (using pip3 without the alias), it seems like there's no way to see the latest logs after running that command nor seeing the actual issue.

The next logs are showed after running the script with the alias included:

pip 21.2.4 from /usr/local/lib/python3.9/site-packages/pip (python 3.9)

ok, that helps a little I think.
Is it possible for you to share the step repo with me so I can dig into this a little more?

[ferPrieto]

I don't have the Step built yet. I was still playing around with the commands I will use in the Step.
As I mentioned at the beginning of this thread, I've been using these two Steps: Brew install Step & Script Step as a Phase 0 of the project.

Hello @ferPrieto,
python3 is also preinstalled, so you should not need to install it. I tried out the xcode-13.4 Stack and could install a pip package:

+ pip3 install celluloid
