I'd like to install ruamel.yaml on an environment which does not have a compiler, and I do not care about the performances.
What is the proper way to install ruamel.yaml w/o pip trying to build the extension and failing to execute the C compiler which is not installed?
I ran
pip3 install ruamel.yaml
which failed with
building '_ruamel_yaml' extension

Testing if compilation worked and skipping compiling the C extensions if it didn't, was removed from
ruamel.yaml
when it was no longer dependent onlibyaml
being available.That of course doens't mean that the C compiler is available, so this should be considered a regression. In
ruamel.yaml>=0.15.41
this should be fixed.
