Dependency handling in boilerplates on Replit, and update status for Python Projects

Describe the Issue

When using boilerplate code forked to the replit, replit used to install dependencies on the first run using the standard packager. That’s not a case anymore for the boilerplates, probably due to some missing required configuration. Replit seems to have changed their dependency handling, relying more on the replit.nix file defining the environment. This affects both JS and Python boilerplates.

Temporal workarounds

JS

npm install seems to do the job, when run manually. It doesn’t run when loading replit or pressing the Run button.

Python

Manual trying to use poetry install doesn’t seem to work. Changing replit.nix (added by the replit on forking) and adding required modules to the deps does the trick, for example, the Arithmetic Formatter requires adding

pkgs.python38Packages.pytest

Medical Data Visualizer at least:

pkgs.python38Packages.pandas
pkgs.python38Packages.seaborn

I wasn’t able to make poetry work, even after adding poetry package to the replit.nix, the poetry install installation was interrupted by error.

Expected behavior

Ideally camper should not be required to make any manual actions to use the dependencies required by boilerplate.

There are two more python projects in the Information Security, but they also don’t need additional dependencies.

Also, just in case anyone missed it I did open an issue for this. Just in case we want to talk about it more in-depth without “polluting” this issue.
