Whenever I launch iTerm2 w/zsh i get the following message:

WARNING: python binary not found on PATH.
zsh-autoswitch-virtualenv plugin will be disabled.

If i type this i get the following path:

~ ❯ echo $PATH                                                 

/Users/macm1/opt/anaconda3/bin:/Users/macm1/opt/anaconda3/condabin:/usr/local/bin:/Users/macm1/Library/Python/3.8/bin:/Users/macm1/.pyenv/bin:/Users/macm1/.pyenv/bin:/opt/local/bin:/opt/local/sbin:/opt/homebrew/bin:/opt/homebrew/sbin:/Library/Frameworks/Python.framework/Versions/3.10/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:~/.dotnet/tools:/Library/Apple/usr/bin:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/Users/macm1/.fig/bin:/Users/macm1/.local/bin:/Users/macm1/.local/bin:/Users/macm1/.local/bin

Also:

~ ❯ which python3                                              
/Users/macm1/opt/anaconda3/bin/python3

~ ❯ python --version                                           
Python 3.9.7

~ ❯ ls -l /usr/bin/python                                      
"/usr/bin/python": No such file or directory (os error 2)

In my zsh shell i have the following:

export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
#export PATH=/Library/Frameworks/Python.framework/Versions/3.8/bin:$PATH
export PATH=/Users/macm1/Library/Python/3.8/bin:$PATH

 # Created by `pipx`
export PATH="$PATH:/Users/macm1/.local/bin"

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!

__conda_setup="$('/Users/macm1/opt/anaconda3/bin/conda' 'shell.zsh' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/Users/macm1/opt/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/Users/macm1/opt/anaconda3/etc/profile.d/conda.sh"
    else
        export PATH="/Users/macm1/opt/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup

Can anyone assist with this?

    Probably the error comes from within the __conda_setup assignment; can you please show us your troubleshooting efforts? Adding echo 'checkpoint 1' >&2 just before the call and a similar checkpoint 2 shortly after should help pinpoint this. (You can't put it immediately after because that will reset the value of $?. Tangentially, see also Why is testing ”$?” to see if a command succeeded or not, an anti-pattern?) Commented Aug 28, 2022 at 6:52
  • My guess is that some of the tools you use for initializing zsh, is trying to invoke Python as python instead of as python3. Commented Aug 29, 2022 at 10:21
  • Obviously you have defined something named python, but it is either not an executable, or if it is one, it is not located in /usr/bin. To find more about what your python really is, enter type -a python Commented Aug 31, 2022 at 9:30
  • Can you please add your entire .zshrc file to your question? The message you posted clearly states your are using the zsh-autoswitch-virtualenv plugin, yet it’s not visible anywhere in the code that you shared. Commented Sep 3, 2022 at 8:25
  • @marlonrichert the .zshrc is too long to post but the plugin appears in the plugins section ''' plugins=( zsh-history-enquirer zsh-aliases-exa git z github gitcd fast-syntax-highlighting zsh-autosuggestions auto-color-ls mistory update-plugin vscode autoswitch_virtualenv $plugins ) ''' Commented Sep 4, 2022 at 9:12

Reset to default

so, the problem is that "zsh-autoswitch-virtualenv plugin" is checking for python on ur system.

enter image description here

but you may have installed python3.

so to fix this, go to ur ~/.zshrc or ~/.bashrc file with vim or nano.

the add this lines at the top:

alias python=python3
alias pip=pip3

I am using pyenv. Below answer helped me since aliasing makes the pyenv behave weirdly. stackoverflow.com/questions/71591971/…
