command not found in terminal of mac

Question

when I open terminal, it is suddenly showing

/Users/mine/.rvm/scripts/rvm:12: command not found: uname
/Users/mine/.rvm/scripts/rvm:29: command not found: ps

and then I tried to run flutter devices or anything else like git status and it says zsh: command not found: flutter is there a way to solve it?

Answer 1

It looks like you mess up your PATH variable. (Your current PATH doesn't contain any location where common utilities are located hence all the commands are not .)

You can try:

PATH=/bin:/usr/bin:/usr/local/bin:${PATH}
export PATH

Another way is that you can "reset" zsh, specify the complete path to the shell:

exec /bin/zsh

or

exec /usr/bin/zsh
