lzma module was not found in python:3-slim

Oh, that is supposed to work with the standard library 😞. Looks like we forgot liblzma-dev as one of the buildDeps (oh, and xz-dev on the alpine images too). Luckily for the slim images, it looks like liblzma5 is already installed so it shouldn't have much affect on the slim image size.

Yes, the library is installed but the development library is required in order to build the module. When I build the slim image adding liblzma-dev in the dependencies, the module is constructed.

Unfortunately I have not tried with the other images.

@fbrr @yosifkit I submitted a pull request #90 addressing this issue a couple weeks ago, any thoughts?

[monoedro]

Indeed, with these dependencies the module works!.

I guess this closes the issue. Thank you.

I'm hitting this in alpine, would be nice to have the fix.

how does one install this thing in a pipenv-created virtual environment?
