Hi. Please provide all or part of the error message you are experiencing.
It works normally on the latest stable version of macOS.

What happens when you follow the Installation in Python guide in the documentation?

Hi,

I am having the same issue... this is the error when using python -m pip install prophet:

RuntimeError: CmdStan failed to install in repackaged directory
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for prophet
Failed to build prophet
ERROR: Could not build wheels for prophet, which is required to install pyproject.toml-based projects

If I try to install with Conda, this is the error:

PackagesNotFoundError: The following packages are not available from current channels:

• prophet

Current channels:

• https://conda.anaconda.org/conda-forge/osx-arm64
• https://conda.anaconda.org/conda-forge/noarch

To search for alternate channels that may provide the conda package you're
looking for, navigate to

https://anaconda.org

and use the search bar at the top of the page.

I have installed both CmdStan and CmdStanPy, and the error persists though.

Thanks

Best,

yes same error Stan error
and conda also not working
when I attempt to other repo like darts it also fail, because it has prophet has dependency

Did you all try to install from it's source?

git clone https://github.com/facebook/prophet.git
cd prophet
pip install .

or

pip install git+https://github.com/facebook/prophet.git

it should work

I have attempted installing from source also, but I get the same CmdStan error

Yes, I've tried and the same error happens. There is another threat in #2402 where a similar issue happens in Windows. I have added the macOS issues there as well.

CmdStan

try to run pip install cmdstanpy and then install the prophet

[ale-dg]

I have tried it... the error still happens...

I get the same error too. Is it to do with MacOS version or Python3 Version?

I found that this can help

Once upon a time I stumbled with this issue. If you're using macOS go to Macintosh HD > Applications > Python3.x folder (or whatever version of python you're using) > double click on "Install Certificates.command" file.

Isn't it for issues when pulling repos?! The issue with Prophet is that it doesn't build the wheel correctly, not that it can't be reached online

From #2438 (comment)

I had the same issue and it appears that the new version of MacOS (13.4) specifically fails to install CmdStan 2.26.1. I created a fork (iamjazzar/prophet) where I changed the CmdStan version to 2.32.0 and the installation works. The only catch here is that I'm using my own repo to install the package:

-e "git+https://github.com/iamjazzar/prophet.git@0591532#egg=prophet&subdirectory=python"

I'm not sure how that would affect the behavior, but I'm happy to open a PR if deems fit.

this #2002 (comment) may help you on Apple M1, without rosetta

We believe 1.1.5 has resolved this, pip install prophet will now use M1/M2 wheels
