error when running pip install fbprophet

Hi, I tried to run pip install fbprophet on docker:

FROM public.ecr.aws/lambda/python:3.8 RUN pip --no-cache-dir install \ ephem \ pystan \ fbprophet

But got the following error: ERROR: Command errored out with exit status 1: command: /var/lang/bin/python3.8 -u -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/tmp/pip-install-l79apfcp/fbprophet/setup.py'"'"'; __file__='"'"'/tmp/pip-install-l79apfcp/fbprophet/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' install --record /tmp/pip-record-9yrgxbdz/install-record.txt --single-version-externally-managed --compile --install-headers /var/lang/include/python3.8/fbprophet cwd: /tmp/pip-install-l79apfcp/fbprophet/ Complete output (10 lines): running install running build running build_py creating build creating build/lib creating build/lib/fbprophet creating build/lib/fbprophet/stan_model Importing plotly failed.

Hey,

I had this problem also but i’ve managed to make it work with the following workaround.

Before installing fbprophet you have to install pystan.

However if you will install like this -> pip install pystan it will fail at building fbprophet because it will grab version 2.19.. that is not compatible with GCC version.

Solution:

1. pip install pystan==2.18.0.0

2. pip install fbprophet

11 months later pip install fbprophet is still broken on Apple Silicon, python 3.9 and python 3.7.
