what does @ mean in case of `pip install <package> @ path`?
Question:
I just came across this from a project on GitHub
pip install colorama @ file:///home/conda/feedstock_root/build_artifacts/colorama_1602866480661/work
what does @ do ?
assuming it decides the path where to install, I tried using any path and it wouldn’t work like that
Also, why would we want to do so?
Also, what is the significance of file:///
Here is the link to the project
https://github.com/sstzal/DFRF/blob/main/requirements.txt
Thanks for your attention
Answers:
This notation with an @
is specified here in the "Direct references" section of PEP 440.
The part after the @
is a direct reference to a location where the project can be installed from (i.e. the source, not the destination).
It can be URL to a file archive (sdist or wheel), or a VCS repository (git, for example).
The file://
notation is meant for the (local) filesystem protocol (as opposed to the https://
protocol for example).
