Conditional requirements in setup.py

阅读更多关于 Conditional requirements in setup.py

问题 I'm writing a library that's dependent on file-magic, which works just fine for most platforms, but in Alpine Linux, file-magic won't work so I need to instead use the python-magic library.

问题 I use libmagic to get the mime type of a file in a web interface of my project. I get text/plain mime type on css and js files. For example chromium shows below warnings: Resource interpreted as Stylesheet but transferred with MIME type text/plain: "http://localhost:8000/jquery-ui.css". Resource interpreted as Script but transferred with MIME type text/plain: "http://localhost:8000/jquery.timers.js".

Compiling libmagic statically (c/c++ file type detection)

My problem is that libmagic seems to require the external file, magic .
