How to downgrade python version from 3.8 to 3.7 (mac)

I'm using Python & okta-aws tools and in order to fetch correct credentials on aws I need to run okta-aws init. But got an error message of Could not read roles from Okta and the system prompted that"Your Pipfile requires python_version 3.7, but you are using 3.8.3 (/usr/local/Cellar/o/1.1.4/l/.venv/bin/python).

I've tried to search all the Pipfiles on the mac and it seems that the Pipflie under my ~/Pipfile and /usr/local/Cellar/[email protected]/3.8.3_2/libexec/bin/Pipfile all have the same python version of 3.8, while the Pipfile under my /usr/local/Cellar/okta-aws-tools/1.1.4/libexec/Pipfile has required python_version = 3.7.

I've been struggling with this for a while and really not sure how I can fix this.

Consider installing pyenv with Homebrew on macOS

brew update
brew install pyenv

OR Clone the repository to get the latest version of pyenv

 git clone https://github.com/pyenv/pyenv.git ~/.pyenv

Define your environment variables (For a recent MacOS you may want to replace ~/.bash_profile with ~/.zshrc as that is the default shell)

echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profile
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(pyenv init -)"' >> ~/.bash_profile
source ~/.bash_profile

Restart your shell so the path changes take effect

exec "$SHELL"

Verify the installation and check the available python versions

pyenv install --list

Install the required python version

pyenv install 3.7

Set it as your global version after installation

pyenv global 3.7

eval pyenv path

eval "$(pyenv init --path)"

Verify your current python version the system is using

python3 --version

  • Reinstalled xcode-select (used solution here)
  • Downgraded python 3.9 to 3.8.12 (used @Shayan's solution here)
  • Restarted terminal and checked default Python version, that's all

This is my solution for M1 Mac

brew only approach.

rm -rf $(brew --repository)/Library/Taps/company
brew tap-new company/team
brew extract [email protected] company/team  --version=3.7.9 
HOMEBREW_NO_AUTO_UPDATE=1  brew install company/team/[email protected]
brew link --force company/team/[email protected]

This creates a local tap, extracts python 3.7.X to a formula in that local tap and then installs and links that formula

The created local tap and the new formula file can be found in $(brew --repository)/Library/Taps/company/homebrew-team

I recommend you to install and use pyenv, a Python Version Management. Once intalled pyenv, install python 3.7:

pyenv install 3.7

And then set the environment PYENV_VERSION to version of python you want to use, on this case will be 3.7:

pyenv shell 3.7
