pip_library absl-py fails on macos

[ngra...@amfam.com]

Hi all,

I'm having trouble installing some pip_libraries on macos. They work fine if I run in a linux docker container.

> cat BUILD

pip_library(

    name="absl",

    version="0.2.1",

    package_name="absl-py"

)

> plz --show_all_output build

Any ideas here?

Thanks,

Any ideas here?

Not immediately, but I will grab one of our Macs and have a go to see if I can reproduce the same thing. Will let you know if I come up with something!

The problem seems to be a combination of a few factors, which I guess is why we haven't seen it before:

 - There isn't a binary wheel uploaded for absl so pip is running setup.py locally

 - Homebrew's pip doesn't support --target readily (https://github.com/Homebrew/brew/issues/837)

 - absl provides its own setup.cfg that seems to obscure the one we provided.

I think I can fix this by changing to write .pydistutils.cfg instead; in the meantime you can add the following to your pip_library rule which should fix it:

    pip_flags='--install-option="--prefix="'
