I had a similar issue with my PATH in https://discussions.apple.com/thread/253548744, which I thought was fixed but I have since installed Homebrew and having a similar problem. All commands such as brew help return:
-bash: brew: command not found
I am not sure of the correct PATH for brew or what to change

If you have Python 3.9 installed via brew (or Python.org) the following PATH change will find Python 3.9, the homebrew binary, and your normal system binaries:
export PATH="/Library/Frameworks/Python.framework/Versions/3.9/bin:/usr/local/bin:${PATH}"
This happens to be my own PATH setting for Bash and Zsh.
You cannot grep a dot directory as you observed. Also note, that there will be links in /usr/local/bin to the Python binaries in that Python framework.

As in that post, start with the following:
/usr/bin/grep 'PATH=' $HOME/.[a-z]*
which should find the offending file and bogus PATH= assignment.
You can use
/usr/bin/nano .name-of-offending-file
to fix the offending file.
Brew lives in
/usr/local/bin/brew
Sorry, I don't know which one is the incorrect file:
/Users/<username>/.bash_profile:PATH="/Library/Frameworks/Python.framework/Versions/3.9/bin:${PATH}"
/Users/<username>/.bash_profile:export PATH=/usr/bin:/bin:/usr/sbin:/sbin
/Users/<username>/.bash_profile.save:PATH="/Library/Frameworks/Python.framework/Versions/3.9/bin:${PATH}"
/Users/<username>/.bash_profile.save:export PATH=’/usr/bin:/bin:/usr/sbin:/sbin
/Users/<username>/.bash_profile.save.1:PATH="/Library/Frameworks/Python.framework/Versions/3.9/bin:${PATH}"
/Users/<username>/.bash_profile.save.1:export PATH=/usr/bin:/bin:/usr/sbin:/sbin
grep: /Users/<username>/.bash_sessions: Is a directory
grep: /Users/<username>/.cache: Is a directory
grep: /Users/<username>/.config: Is a directory
grep: /Users/<username>/.cups: Is a directory
grep: /Users/<username>/.idlerc: Is a directory
grep: /Users/<username>/.oracle_jre_usage: Is a directory
grep: /Users/<username>/.viminfo: Permission denied
grep: /Users/<username>/.vscode: Is a directory
Thanks,
I am not sure what you mean. I use the pre-installed version of python and I changed this PATH but it did not work. Was I supposed to replace the line PATH="/Library/Frameworks/Python.framework/Versions/3.9/bin:${PATH}" with:
export PATH="/Library/Frameworks/Python.framework/Versions/3.9/bin:/usr/local/bin:${PATH}"?
I also found that when installing Homebrew, it gave the warning:
Warning: /usr/local/bin is not in your PATH.
I don't know if this is significant or not
You do not need a PATH statement that includes that Python 3.9 entry when using the default Python 2.7.16 on Catalina. Just do this:
export PATH="/usr/local/bin:${PATH}"
and depending on your shell:
source ~/.bash_profile
source ~/.zshrc
to make that PATH effective in the current Terminal session.
Not only does this now give you access to brew, but also that /usr/bin/python that is linked to its bin directory in the System's Python.framework.
However, some brew-installed packages may have a dependency on Python3 and brew will attempt to install it in /usr/local/bin with links to that /Library/Frameworks/Python.framework.../3.9/bin location. This does not matter unless you attempt to use Python3 or idle3.
A few things.
If you have switched over to zsh, as VikingOSX has implied, then your .bash_profile is not going to be executed, unless you either transfer the important stuff over to the appropriate zsh initialization script, or you source your .bash_profile from one of your zsh initialization scripts.
In your .bash_profile you have 2 export PATH statements
/Users/<username>/.bash_profile:PATH="/Library/Frameworks/Python.framework/Versions/3.9/bin:${PATH}"
/Users/<username>/.bash_profile:export PATH=/usr/bin:/bin:/usr/sbin:/sbin
The 2nd one totally undoing what the first one did. So in theory you have a valid PATH, but it does not include the Homebrew directory. Again VikingOSX has suggested a solution for that.
Mostly, I'm saying what VikingOSX is saying, only different 😀
Sorry, I have realised that I use python 3.9 (I must have installed an update at some point and forgotten about it), so I changed the PATH to:
export PATH="/Library/Frameworks/Python.framework/Versions/3.9/bin:/usr/local/bin:${PATH}"
and this seemed to work. Thanks both of you for the support on this issue
Happy New Year, Bob. However you want to say it…😎
You are welcome.
