pip error while installing spacepy on Pycharm (Mac)

Question

I'm trying to install the spacepy package on Pycharm (Mac), but the installation keeps failing.

note: This error originates from a subprocess, and is unlikely a problem with pip

Console output:

  ERROR: Failed building wheel for spacepy
Failed to build spacepy
ERROR: Could not build wheels for spacepy, which is required to install pyproject.toml-based projects

What can I do to get past this issue? Here's what I've tried in the Python and Mac terminals, but I still receive the message above:

pip install spacepy
pip install --no-cache-dir spacepy 
pip install --upgrade pip
pip install --upgrade setuptools
pip install --upgrade wheel
pip install spacepy --user
pip install --no-cache-dir spacepy

I'm a new Mac user, so if anything can be dumbed down for me that would be greatly appreciated. Also, please let me know if there's any information you may need me to include.

Please [edit] the question and add the full formatted text of the error message. — phd, May 24 '22 at 19:52
SpacePy currently [doesn't provide binary wheels](https://pypi.org/project/spacepy/0.3.0/#files) for MacOS X so `pip` tried to compile from sources and failed not founding a Fortran compiler. Try to install with Anaconda. See https://spacepy.github.io/install.html, https://spacepy.github.io/install_mac.html and https://spacepy.github.io/install_linux.html — phd, May 25 '22 at 21:50
I installed a Fortran compiler and now it's working. Thank you! — nq209, May 26 '22 at 17:09

If you are using MacOS or Windows, try installing gfortran.

(If you are using Linux, try installing gcc-fortran)

For Mac, there is a possible workaround for this problem if you use Conda. The idea is to create an x86 environment on the Mac and do your pip install after that.

conda create -n <name>
conda activate <name>
conda config --env --set subdir osx-64
conda install python=3.8

Here I choose Python 3.8, but you can choose another version.
