What is the version of your Python? I have a feeling the requirements.txt file isn't updated for Python 3.8

[eamGit]

Python version 3.7.5

Can you give us the results of running conda info while you have your environment activated?

The issue here is that the fbprophet-feedstock hasn't been updated for Py3.8. The automated attempt to do this failed (https://github.com/conda-forge/fbprophet-feedstock/pull/22) and now I'm first fixing a new issue related to the holidays package (https://github.com/conda-forge/fbprophet-feedstock/pull/25) and then will re-try the build for Py3.8.

[bletham]

I just rebuilt fbprophet in conda forge with the new version (0.6), so this should be resolved now.

[osguru]

fbprophet is not compatible with python 3.8.

Requirement pystan has package for python 3.8 and successfully installed for anaconda.

Kindly create fbprophet package for python 3.8.

Thanks

Here is output:

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

• fbprophet -> python[version='2.7.|3.5.|3.6.*|>=2.7,<2.8.0a0|>=3.5,<3.6.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0']

Your python: python=3.8

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that..

I had thought this would happen automatically with the v0.6 push when I closed it, but then found out in https://github.com/conda-forge/fbprophet-feedstock/pull/30 that it hadn't. I got a bit stuck on that (some really bizarre build issues) and lost track of this issue. I just asked the conda forge bot to re-try the build for py38 so hopefully that works, but if you have any experience with conda forge please do help out over on that PR.

Hi, any update on this?
I'm still unable to install FB Prophet while on Python 3.8.

This should be fixed now by https://github.com/conda-forge/fbprophet-feedstock/pull/33, which got fbprophet to build in py38. If anyone is still running into issues with this please reopen!
