Cannot install pygrib due to missing component

[heliosilver97]

Good afternoon!

I'm trying to install the pygrib library to run in VS Code, but I'm not succeeding. When I go to install, the following reason appears:

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

I researched the error and i found that the error suggests that the build process of the pygrib package is failing due to the absence of the grib_api.h file, which is part of the libeccodes library. How i can fix this issue? Because i already installed the eccodes package, and the same issue still happens.

if you use 'pip install' it should install a binary (no need to compile, all required c-libs bundled). x86_64 windows and linux wheels are available for python 3.7-3.12. What platform/python version are you using?

I have the same problem. I use Python 3.12.0 on Windows 11.
Here is the output error :

I looked for a solution, but I can't find it.
Thanks for your help.

sorry I misspoke earlier - we only have macosx and linux binary wheels. Windows is not supported. However, it looks like you can install pygrib on windows via conda (https://anaconda.org/conda-forge/pygrib)

[jswhit]

@fguenot @heliosilver97 please let us know if you're able to get up and running using the conda package

[jswhit]

You can use the ECCODES_DIR env var (see https://jswhit.github.io/pygrib/installing.html#instructions)

[carlosloslas]

Hi @jswhit,
I was able to get pygrib working on windows with conda by running the following on Windows PowerShell:
& "C:\Users\carlosl\AppData\Local\anaconda3\Scripts\conda" install conda-forge::pygrib

Of course the path will change depending on the location where anaconda has been installed. I think we can close this issue 😄
