ERROR: Failed building wheel for fbprophet

• pip version: 20.3.3
• Python version: 3.8
• OS: macOS 10.15.7

Attempted to install fbprophet using pyenv+pip. error: command 'clang' failed with exit status 1

1. Checked gcc, updated Xcode etc.
2. Uninstalled/installed pystan, cython - various versions
3. Installed minconda for testing
4. Installed fbprophet via conda+pip ERROR: Command errored out with exit status 1:, ERROR: Failed building wheel for fbprophet message continues… DEPRECATION: fbprophet was installed using the legacy 'setup.py install' method, because a wheel could not be built for it. pip 21.0 will remove support for this functionality. A possible replacement is to fix the wheel build issue reported above. You can find discussion regarding this at https://github.com/pypa/pip/issues/8368. message continues… Successfully installed Cython-0.29.21 LunarCalendar-0.0.9 cmdstanpy-0.9.5 convertdate-2.2.0 ephem-3.7.7.1 fbprophet-0.7.1 holidays-0.10.4 korean-lunar-calendar-0.2.1 pymeeus-0.3.7 pystan-2.19.1.1 pytz-2019.3 setuptools-git-1.2 tqdm-4.54.1

Conda+pip seems to be able to fix the issue itself using an older setup.py. Good for conda users, but I don’t use conda and many don’t use conda. pyenv+pip is a no go.

1. Are you aware of this?
2. Is there are way for me to install fbprophet via conda into a pyenv environment? 🤡

Thanks for the work. It seems like you’re another project blocked by this problem. Hopefully we can come up with a solution soon.

Would fbprophet be interested in opting into PEP 518? I cannot tell the maintainers’ stance on this from reading the linked issues. The required pyproject.toml should be quite straightforward, I can probably submit a PR if the y’all don’t object.
