The error message "no such file or directory" means that the file or directory specified in the command doesn't exist or isn't accessible. In this case, it seems like the brew executable isn't present in the expected location /opt/homebrew/bin/brew.
Here are some solutions:
Check to see if Homebrew is installed and installed correctly. You can try reinstalling Homebrew or updating the existing installation.
Verify that the brew executable is in the PATH environment variable. You can check this by running the command echo $PATH and looking for /opt/homebrew/bin in the output. If it's not there, you can add it to the PATH variable.
Try working the full path to the brew executable, like /opt/homebrew/bin/brew.
