Cannot use 'pip install fbprophet' to install prophet on mac about prophet

[BruceBinBoxing]

As @matse004 said, using pystan==2.17.1.0 rather than 2.18 works for me!
Do as bellow:

sudo pip uninstall pystan
sudo pip install pystan==2.17.1.0
sudo pip install fbprophet

[Tafkas]

The fbprophet package requires pystan, which requires Cython. Try installing Cython with

pip install Cython

This should fix the issue.

[philipperemy]

I had the same issue and I could make it work that way:

git clone --recursive https://github.com/stan-dev/pystan.git
cd pystan
python setup.py install
pip install fbprophet

[hassheh]

I have the same issue. I have tried all the mentioned fixes including downgrading pystan from 2.18 to 2.17.1.0 but still, it gives this error.

error: command '/usr/bin/clang' failed with exit status 1

[plank3ffect]

Actually, I just got it working. From the FB Prophet GitHub, they acknowledge that the pystan 3.0.0 version broke fbprophet (#1856). The team is currently working on a new version and should publish soon. In the meantime, i had to do a pip uninstall pystan to remove 3.0.0 and then install using pip install pystan~=2.14 to install an older version. It seems the newer pystan 3.0.0 calls their module stan instead of pystan, which was breaking a few things. There were probably more changes to the updated pystan rewrite.

[matse004]

Run into the same issue on MacOS ElCapitan (10.11.6). Nothing worked for me except for manually downgrading pystan package from 2.18 to 2.17.1.0.

[jeroenjanssens]

I just want to chip in by saying that @anshul-tak's solution worked for me as well. Thanks for that, @anshul-tak.

For what it's worth, I use env CC=$(which gcc-9) CXX=$(which g++-9) pip install fbprophet which (no pun intended) is slightly more sustainable should the version of gcc change (currently it's at 9.2.0_3).

[olivboom]

Installing via Conda fixed all problems for me

[anshul-tak]

Another solution that worked for me is force pip to use homebrew GCC compiler instead of CLANG

1. After installing homebrew
   env CXX=/usr/local/Cellar/gcc/9.2.0/bin/g++-9 CC=/usr/local/Cellar/gcc/9.2.0/bin/gcc-9 pip install fbprophet==0.4.post2
   or Add env variable in your bash rc file.

reinstalling pystan on macOS Big Sur didn't help me!
I properly installed fbprophet using pip after running the following:

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

[exxcong]

Hey @gregwalla, I'm also on Big sure, 11.2.1 at this point. I tried normal pip install, conda install, nothing worked, until I followed the advice of @BruceBinBoxing and downgraded pystan. This worked. For a mac I don't think we need to sudo, but it also didn't hurt, I used it verbatum:

sudo pip uninstall pystan
sudo pip install pystan==2.17.1.0
sudo pip install fbprophet

Thanks a lot! I use mac M1 with Big Sur. I tried all kinds of methods and all failed. But I used your method and it succeed. Thanks!

[seanyboi]

I'm going to add my two cents, if any one is still having problems make sure you update your Xcode using:
xcode-select --install
This was my lifesaver along with making sure pystan is installed BEFORE you install fbprophet

[GwenVCX]

My environment:
OSX : Big Sur 11.6
python : python:3.7-slim

$ pip install pystan==2.19
$ pip install fbprophet

[espoirMur]

xcode-select --install

reinstalling pystan on macOS Big Sur didn't help me!
I properly installed fbprophet using pip after running the following:

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

Thanks @mahanh this help to solve the issue on my side

Thank you @plank3ffect! My error was 'unable to find module pystan', even though it was installed.
This helped fix the issue.

[l0vest0rm]

the problem exists when Cython already installed

[seanjtaylor]

This question suggests that maybe your XCode is outdated. Can you check cc --version. Here's mine:

sjt-mbp1:examples sjt$ cc --version
Apple LLVM version 8.0.0 (clang-800.0.42.1)
Target: x86_64-apple-darwin16.4.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

[l0vest0rm]

it is ok now when i installed the xcode,thanks to seanjtaylor

[stories2]

Failed install fbprophet.
sudo pip3.5 install fbprophet

It stocks in Downloading fbprophet-0.1.1.tar.gz

I already installed Xcode and Cython.

Apple LLVM version 8.1.0 (clang-802.0.42)
Target: x86_64-apple-darwin16.7.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

[thomzi12]

FWIW I am encountering same issue as @stories2

My cc --version:

Apple LLVM version 8.1.0 (clang-802.0.42)
Target: x86_64-apple-darwin16.7.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

Update: installing via conda works for me

[stories2]

@thomzi12 In my case, it just took soooooooooooo long time.
Drink coffee. The time will solve your problem :)

[jisumanbu]

Same issue I met when I install pystan (2.18.0.0) & fbprophet (0.3.post2) on macOS(10.13.6)
Issue disappeared after downgrading pystan from 2.18 to 2.17.1.0 as matse004's suggestion.

[maddy2u]

Installing via Conda fixed all problems for me

This is the only thing that worked for me in the whole thread.

[buxizhizhoum]

export CC=$(which gcc)
export CXX=$(which g++)
pip install fbprophet
And my error is: error: command 'clang' failed with exit status 1
This works, thanks @anshul-tak

[andreamoro]

Hi, I have the same problems in installing Prophet. Irrespective of the two exports above, I still get the following error:

I'm not using Anaconda or anything like it, Xcode is installed.
As far as I can understand from the above, it seems the error code is due to some writing permission, which as a matter of fact are correct because on this working laptop IT prevents me to write into the private folder.

I had a look at the settings, but couldn't spot anything that allow me to specify a different folder.

Has anybody had a similar issue?

Thanks
Andrea

[vemuri-nath]

@andreamoro facing the same problem as you mentioned. Please update me if you find a solution
thanks

[andreamoro]

It might me a problem with pystan, which relies on C++ libraries that are not found where expected. I'm trying to speak with a developer there. Are you able to run pyStan and a demo example with success on your end @vemuri-nath ?

[gregwalla]

Same problem here , nothing seems to work. I am on MAC OS BIG SUR 11.1
Additional requirements :

• I use a venv for 'light weight' reproductibilty.

[erikabergman]

Hey @gregwalla, I'm also on Big sure, 11.2.1 at this point. I tried normal pip install, conda install, nothing worked, until I followed the advice of @BruceBinBoxing and downgraded pystan. This worked. For a mac I don't think we need to sudo, but it also didn't hurt, I used it verbatum:

sudo pip uninstall pystan
sudo pip install pystan==2.17.1.0
sudo pip install fbprophet

[plank3ffect]

Could it be that we are using pyenv and virtualenv? Mine fails as well because it cannot find pystan, which I definitely installed. It is executing from a /private/ folder.....

File "/private/var/folders/km/1jh10x6x4l11w3bmxqrbgtp40000gn/T/pip-install-ppew3k63/fbprophet_263d1ca7a61543b0bfe1544fa2f11904/fbprophet/models.py", line 209, in build_model import pystan ModuleNotFoundError: No module named 'pystan'

Any ideas on how to specify the pystan from the virtualenv when installing fbprophet? Or am I off base?

[andreamoro]

It seems this error still persists with pystan 3.2.0. Am I wrong?

I cannot install the library at all. Anybody else?

[sarvesha-jaiswal]

when i tried installing fbprophet I've got the same error?
anyone know how to install it ?
