does pypi2nix respect $http_proxy/$https_proxy

Here's my output

@krey pypi2nix does not respect $http_proxy/$https_proxy. since - as you can see - we run nix-shell command with --pure flag. I think we should create a whitelist of environment variables which should be passed down to nix-shell. Would you be willing to implement this?

[spinus]

I'm not a big fan of reimplementing the same in every app. @krey is tsocks not working?

[garbas]

this would be easier to implement now with nix run and its option --ignore-environment and --keep

Hello,

What would be the solution to bypass it? I try this :

nix run -i -k https_proxy nixpkgs.pypi2nix -c pypi2nix -V3 -r ../requirements.txt 
pypi2nix v1.8.1 running ...

I have the same limitation. While all nix-tools work well with the proxy, pypi2nix does not, unfortunately. Why not passing as command line arguments to the underlying libraries as alternative.
