Does not create executables?

[turion]

I tried:

$ pypi2nix -e csvdiff
$ nix-shell requirements.nix -A interpreter
$ csvdiff
csvdiff: command not found

[seppeljordan]

Can you please provide the output of the pypi2nix command?

Or did you mean the generated files?

Note that there is a tiny chance that it's an upstream error and csvdiff is broken (in that it doesn't contain a proper executable). I haven't been able to rule that out yet.

[turion]

I now understand that the executable can be found in ./env/bin/. I expected it to be in the path. So if that's intended behaviour, we can close.

Easiest thing I've found is to do PATH=$PATH:$(nix-build requirements.nix)/bin nix-shell requirements.txt
