Using venv for MicroPython

[saraverbeecke]

Hi,
I'm using the new mip tool to install some libs and it works great, but does anyone know if we can create a virtual env like we use to do for standard python: python -m venv my_virtual_env?
I don't want to mess up my global unix port of micropython and instead use separate virtual envs for my MicroPython projects...
Any help/tips welcome!
Thanks!

I think you can run mip with the --target option to install packages to a specific directory, then set the MICROPYPATH environment variable to that path before running micropython.

Thanks! I wasn't aware of this option yet :-)

We provide a micro version of the venv library in MicroPython lib that you can install on the unix port. You can install this via mip. We are considering making it included by default in the unix port.

So:

# install venv package globally
$ micropython -m mip install venv
# create a new venv
$ micropython -m venv venv-path
# enter venv (same as in CPython)
$ . venv-path/bin/activate
$ # now inside micropython venv
...
$ deactivate

Wow that is even more interesting! Is there some sort of mip freeze command to create a requirements.txt file?

There isn't.

I am planning the opposite which is a way to consume a requirements.txt file or equivalent (i.e. manifest.py).
