Visidata: "No module named 'requests'" when loading wikipedia URL on NixOS

[WesleyAC]

Small description

I ran vd https://en.wikipedia.org/wiki/New_York_City_Subway_stations, on NixOS (using the visidata nixOS package).

Expected result

visidata runs and opens the tables in the requested wikipedia page

Actual result with screenshot

Traceback (most recent call last):

Hi! =)

There are a lot of data format loaders, most with their own dependencies, and we made a decision to not have any of the dependencies install by default. We left it with the package maintainers to decide which they wanted to include in the various packages.

If you think requests should be included in the NixOS one by default, their repo is the place to write the issue. That is actually one of the packages that I do not maintain. I am not familiar enough with NixOS to be able to write for you a workaround. =(

@WesleyAC visidata.overrideAttrs (x: { propagatedBuildInputs = x.propagatedBuildInputs ++ (with python3Packages; [requests]);}) (I would comment in a Nixpkgs issue if there was one…)
