Copied from an email from Soumen Basak

I am unable to install the "PY3NJ" package in Thonny (https://thonny.org/). The installation error message had a single-version-externally-managed flag. The page https://pypi.org/project/py3nj/ says Python 3.6 only. This suggests that it is incompatible with the interpreter that Thonny is using (in my case 3.7.7). So, I request you to update P3NJ such that I can install it in THONNY.

fujiisoup commented 3 years ago

py3nj is tested also with python 3.7.

Can you leave the detailed error message? Although I don't use THONY, I'll take a look.

Thanks for posting the error message. It looks that you don't have a Fortran compiler.

Please install gfortran or its alternative. I think this page helps. https://scipy.github.io/old-wiki/pages/F2PY_Windows.html

soumenbasak commented 3 years ago

I use mac osx. Please send me the same link for mac

Is the error message then same? Then maybe the compiler cannot be seen from the python environment.

I don't know how Thony works. Maybe installing py3nj from pip solves the problem?

soumenbasak commented 3 years ago

See the attachment for the error messages. I use Thonny for my work. So, i need to call py3nj functions in my code. Otherwise it will be very inconvenient for me to use py3nj.

Does py3nj work in python3.6 only or does it work in python3.7 as well ?

py3nj is being tested also with python 3.7. This is not the python compatibility problem, but the problem of the environment construction.

If you have specific suggestions, that may resolve this issue, for him, please let me

Please ask him to expose your fortran compiler to python.

SergeiDBykov commented 3 years ago

Have the same issue of MacOS with gfortran, gcc, etc installed. Any ideas what to do?

fujiisoup commented 3 years ago

@SergeiDBykov Thanks for your post. Are you also using THONNY?

Could you post the error message here?

SergeiDBykov commented 3 years ago

@SergeiDBykov Thanks for your post. Are you also using THONNY?

Could you post the error message here?

Sure, thanks, here it is: https://pastebin.com/ahJynN4E

I use anaconda, not THONNY, but I think it does not matter since the problem is in installation, not execution.

SergeiDBykov commented 3 years ago

Hey @fujiisoup @soumenbasak, I solved the problem (at my second laptop, I will try on my first one tomorrow)

this solution works:

env CC=/usr/local/Cellar/gcc/10.2.0_2/bin/gcc-10 pip install py3nj

wheree 10.2.0_2 is the latest version of your gcc.

fujiisoup commented 3 years ago

@SergeiDBykov Thank you! This info helps as I don't have a macOS.

I'd try updating setup.py to avoid this confusion.

If you have any spare time, could you try the following

pip install git+https://github.com/fujiisoup/py3nj@openmp_in_macos

without setting the environmental variable?

It would be nice if other macOS users will not be bothered again.

SergeiDBykov commented 3 years ago

Sure, I'll try tomorrow when I get to work.

SergeiDBykov commented 3 years ago

@fujiisoup Hi, your build does not help so far, here is the error: https://pastebin.com/C055RT2z

I did install the package at my second laptop, but have to do this beforehand:

brew install llvm libomp

export PATH=/usr/bin:$PATH

env CC=/usr/local/Cellar/gcc/10.2.0_2/bin/gfortran pip install py3nj

may be env CC=/usr/local/Cellar/gcc/10.2.0_2/bin/gcc-10 pip install py3nj also works, but I have not tried

fujiisoup commented 3 years ago

@SergeiDBykov Thank you for your help. It looks be difficult for me to improve this issue without macOS. I'll just add some tips on readme and wait for contributions from mac users.

Thank you for raising an issue.

Rody50 commented 3 years ago

Hi @fujiisoup @SergeiDBykov, I had the same error message as Sergei while trying to install the package and I could resolve it by using Sergei's solution: env CC=/usr/local/Cellar/gcc/10.2.0_4/bin/gcc-10 pip install py3nj

fujiisoup commented 3 years ago

@Rody50 Thanks for the report!

A contribution to our setup.py is very welcome!

Hi, I think I tried almost all the available solutions in the other issues for MAC OS installation but nothing seems to work. The more interesting part is that I have been using py3nj extensively and only now see an issue when trying to create a different environment. What I then did was I went back to the environment I use all the time and uninstalled py3nj using pip uninstall py3nj and then attempted reinstalling by pip install py3nj and end up with this error

Hi @srijaniiserprinceton It looks like you need OpenMP installed in your system. I am not familiar with mac, but probably brew install libomp does it

srijaniiserprinceton commented 10 months ago

Hi @fujiisoup

I had tried brew install libomp earlier but it gives me the same error. I tried downgrading python to 3.7 and re-ran the installation. I even made sure I installed gfortran in the local environment and it still returns me the following error

I think I am most confused with the line ../meson.build:1:0: ERROR: Compiler /Users/srijanbharatidas/opt/anaconda3/envs/astero_avni/bin/x86_64-apple-darwin13.4.0-gfortran cannot compile programs.. I have also tried the solution suggested above by @SergeiDBykov with 

env CC=/usr/local/Cellar/gcc/13.2.0/bin/gcc-13 pip install py3nj

but that returns me the same error with x86_64-apple-darwin13.4.0-gfortran replaced by gcc-13.
