Looks like I have managed to scramble my path variable when installing flutter, and now running yarn, shows zsh: command not found: yarn
This was the command I ran that I started experiencing the zsh command not found:
echo 'export PATH="$PATH:[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin >> ~/.zshrc"
I ran the code solution suggested by @devnull https://stackoverflow.com/a/18428774/1766068
PATH=/bin:/usr/bin:/usr/local/bin:${PATH}
export PATH
it would work when I open a new tab, but if I should restart the terminal it no longer works.
Open your ~/.zshrc
file in a text editor and remove the last line. Then logout and login again.
