I stumbled upon something interesting regarding these two lines when I tried setting up a machine on Colab to run my TPU tests.

When you run PACKAGE_NAME=lite pip install -e .[dev], it will write _PACKAGE_NAME = "lite" in setup.py. This is done by these quite surprising lines of code: https://github.com/Lightning-AI/lightning/blob/master/setup.py#L72-L78

When you run PACKAGE_NAME=pytorch pip install -e .[dev] it installs once again lightning_lite because the PACKAGE_NAME variable is simply ignored.

You can see it in the logs of the run on the master branch:

When running PACKAGE_NAME=lite pip install .[dev] without the -e option, it does not override the code in setup.py, so I could successfully set up the libraries like this.

Mysteriously, the tests that require pytorch_lightning run successfully, so it must be installed somehow. I presumed that it may come pre-installed in the docker image, but I couldn't deduce it from the commands given on the docker hub page.

Yes, and I think it is rightthat the next env. variable is ignored because aside from the edit of setup.py also, MANIFEST.in is updated...

TLDR, I think we can drop -e from all CI 🦦
