Can't install pandas and other python libraries on Mac M1

Question

Fist I had lots of problems installing numpy library on a new Mac book M1. (mostly with pep517) and finally I installed it using python3 -m pip install --no-binary :all: --no-use-pep517 numpy==1.20rc1 command and now, when I try to install pandas (with pip3) library, I face a long list of errors:

How can I install pandas?? other libraries like scipy also face similar errors (some errors about clang.

Answer 1

I solved this by following the steps on this link: https://laict.medium.com/install-python-on-macos-11-m1-apple-silicon-using-pyenv-12e0729427a9

Allowed me to install pyenv via homebrew and pyenv install python 3.8.6. once that was installed I was able to pip install everything I needed (including numpy and pandas which I have seen many other people have issues with). However, I previously tried to do all of this with 3.7.10 but ran into some issues similar to yours.

Im still unsure how to install python3.7 on mac M1 unfortunately.

Answer 2

I used homebrew to install python and numpy, but got the same error message when trying to install pandas using pip.

I could get pandas to work installing it from source (https://github.com/pandas-dev/pandas/releases)

Unzip the downloaded file and navigate to the root folder.

• pip3 install cython
• python3 setup.py install

Answer 3

i solved the problem using arch x86_64 pip3 install <package> Apparently arm64's M1 doesn't support some python libraries yet!
