When no wheel available, all output of build process is swallowed, making it appear as if pip froze

[untitaker]

This has also been an issue with snaek. When you install a package without wheels, installation might take a very long time (particularly when rustc is involved). The user isn't notified about that and might get the impression that the installation froze.

I attempted a patch to forward all output from the build functions (i.e. cargo's output), but it seems like this requires a lot of workarounds.

You can show the build output by enabling verbose mode in pip:

pip install -v --editable .

This might make sense for filing against pip (eg: maybe show a yarn style one liner progress bar with stdout?)

Like this:

I think -v is fine for my usecase, thanks.
