Prophet: fbprophet installing error

[bicsu]

First, I am using ubuntu and used command 'conda install -c conda-forge fbprophet'
it didn't work.

my error is like below:

Is this the output of the conda-forge install or a pip install? Conda-forge doesn't yet have v0.4 so I'm wondering if this is pip.

It seems that pystan is not working, which is causing the model compiling to fail when installing fbprophet. Try re-installing pystan through conda forge and then check that it is working by running:

import pystan
model_code = 'parameters {real y;} model {y ~ normal(0,1);}'
model = pystan.StanModel(model_code=model_code)  # this will take a minute
y = model.sampling(n_jobs=1).extract()['y']
y.mean()  # should be close to 0

0.4 is now on conda forge, so installing it from there should resolve the issue.

I've had the same problem. But it works after I follow this steps:

On Prompt install Ephem:
conda install -c anaconda ephem

Install Pystan:
conda install -c conda-forge pystan

Finally install Fbprophet
conda install -c conda-forge fbprophet

Lonely：if you don't have conda or even you have conda，you can use these two simple command:
python3 -m pip install pystan==2.17.1.0 -i https://pypi.tuna.tsinghua.edu.cn/simple
and then
python3 -m pip install fbprophet -i https://pypi.tuna.tsinghua.edu.cn/simple
now, you may success~

I resolved this issue on my Fedora 31 machine using:

sudo dnf install gcc-g++

I prefer dnf over yum, but either way, leaving this comment in case it helps anyone else.

For those who might face the same issue in centos with version around 7.8, downgrading the pystan is exactly the way to solve the problem.
Thanks again for posting.
