Speed hack

[lainisourgod]

I've lurked through many solutions on speeding up pyenv and the only one worked by far, so for anyone lurking it can be helpful to know.

I'm posting it in another because other speed-related issues are closed.

• Install https://github.com/kkysen/pyenv-python/ for faster python shim
• Put this in your [sourced only on login so not to clutter PATH variable] .zprofile (for zsh) or .profile (for bash):

  # Note: cargo bin dir is before pyenv bin dir so `python` is evaluated to `pyenv-python` shim
  export PATH="$HOME/.cargo/bin:$PATH"
  export PYENV_ROOT="$HOME/.pyenv"
  export PATH="$PYENV_ROOT/bin:$PATH"
  eval "$(pyenv init - --no-rehash)"

• I needed to create python3 shim in ~/.cargo/bin/ so it worked correctly: cd ~/.cargo/bin; ln -s python python3

This eliminates all problems I had:

• Slow startup time because of pyenv
• All oh-my-zsh plugin initialization was slow after doing pyenv init -
• Running commands was slow
• Some other solutions broke pyenv's functionality

Hope it helps!🤞
