Pyenv cannot install python on MacOS M1

Question

Pyenv will not install any version of python on my system (MacOS M1).

Here's the output from the terminal session:

pyenv install 3.9.0

I tried using the arch prefix as well:

arch -x86_64 pyenv install 3.8.9

Snippet from .zshrc:

# Pyenv
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zshrc
echo 'command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.zshrc
echo 'eval "$(pyenv init -)"' >> ~/.zshrc
# Pyenv-virtualenv
eval "$(pyenv virtualenv-init -)"

export PYENV_ROOT="$HOME/.pyenv"
command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"

Pyenv version: pyenv 2.3.1

Update: Resolved. It was a compatibility issue. pyenv doesn't support M1 for older versions of python (3.6/3.7/etc). Installing 3.7.13 or 3.10.0 both work.

Answer 1

I am using M2 Ventura 13.2

1. arch -arm64 pyenv install 3.11.1
2. pyenv virtualenv 3.11.1 artifact
3. pyenv local artifact
4. pip install --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cpu
5. Check in the shell

>>> import torch

>>> torch.backends.mps.is_available()

True
