I am running pip3 install -U scikit-learn to install Scikit-learn however it returns an error:

What can I do to fix this in order to sucessfully install Scikit-learn?
it worked for me.

I am trying to install the pynbody package for python.
I run pip3 install pynbody, but the command fails.
It says:
ERROR: Could not build wheels for pynbody which use PEP 517 and cannot be installed directly
Before it gives the error:
error: Command "/usr/local/bin/gcc-10 -Wno-unused-result -Wsign-compare -Wunreachable-code -fno-common -dynamic -DNDEBUG -g -fwrapv -O3 -Wall -arch x86_64 -g -I/private/var/folders/5q/xc22bbms0qjdgmpsv2188ydh0000gn/T/pip-build-env-q66c57aj/overlay/lib/python3.9/site-packages/numpy/core/include -I/Library/Frameworks/Python.framework/Versions/3.9/include/python3.9 -c pynbody/gravity/_gravity.c -o build/temp.macosx-10.9-x86_64-3.9/pynbody/gravity/_gravity.o -fopenmp" failed with exit status 1
I have MacOS 11.0.1 and python 3.9.0 and pip 20.2.4.
I can install other packages via pip such as numpy.
How can I install pynbody on MacOS?
(The same procedure worked on ubuntu.)
The Xcode developer tools are installed.

I've been looking for an answer to this issue but I couldn't find it, so here it is.
I'm trying to install tesserocr into MacOS X Mojave (Python 3.6) using:

I am trying to install pyamg in my virtual environment. However, I am getting the following error. I am using mac OS.

Use Anaconda or Miniconda
conda install pyamg
takes only a few seconds.
You can create an environment with:
conda create --name my_env python=2.7
Change into it:
source activate my_env
and install pyamg:
conda install pyamg
You can still use pip to install packages conda cannot find.
Life is too short to spent time on compilation issues. ;)
I'm pretty sure that the -I at the beginning of the paths is what's screwing everything up. I bet if you tried adding those export statements back to .bashrc but took out the -I and -L prefixes then your original command would start working.
Perhaps you had those there for a reason, I've never seen that, but removing those prefixes would probably work.
Actually, I think #oarfish called it correctly in the comments. The problem seems to be the funny “ and ” characters in those paths, which are distinct from the usual " double quote symbol.
The following reproduces the error for me:
