I installed homebrew 3.0.0 on my M1 MBA.
However, every session including iterm2 terminal and tmux shows this error message:
/Users/jinrae/.zprofile:1: no such file or directory: opt/homebrew/bin/brew
In my case, it does not harm functionality at least in my usage pattern.
Anyhow, how can I get rid of this message?
I got this error because I installed brew on the Rosetta version of terminal to install packages, that are not yet M1 compatible.
To get rid of this message i opened my .zprofile with nano .zprofile.
The first line was
eval "$(/opt/homebrew/bin/brew shellenv)"
And i simply put a # before this line to comment it out and the message was gone.
To @sedavidw, /opt/homebrew/bin contains .keepme without contents:
/Users/jinrae/.zprofile:1: no such file or directory: opt/homebrew/bin/brew
➜ bin pwd
/opt/homebrew/bin
➜ bin la
total 0

EDIT: I read an article saying that homebrew is installed in /opt/homebrew/bin in M1 Mac whereas it is installed in /usr/local in Intel Mac. I'm trying to reinstall homebrew for M1 Mac now.
EDIT2: I solved the problem. It was due to for what homebrew is installed. As I heard, homebrew is installed in /usr/local for Intel Mac and /opt/homebrew/bin for M1 Mac.
I reinstalled homebrew with
/bin/bash -c "$(curl -fsSL https://gist.githubusercontent.com/nrubin29/bea5aa83e8dfa91370fe83b62dad6dfa/raw/48f48f7fef21abb308e129a80b3214c2538fc611/homebrew_m1.sh)"
which is slightly different from that in the official site (at least to me).
Anyhow, newly installed homebrew is located in /opt/homebrew/bin and the problem has been solved.
If you are using an Intel Mac, as mentioned above, Homebrew gets installed on /usr/local. Therefore, modify your .zprofile file (located in users/<username>) to use the correct path. Here is content of .zprofile:
eval "$(/usr/local/Homebrew/bin/brew shellenv)"
I have the M1 Mac and it was installed in /opt/homebrew/...
I opened /Users/~username~/.zprofile and it had two lines.
First line was:
eval "$opt/homebrew/bin/brew shellenv"
Second like was:
eval "$(/opt/homebrew/bin/brew shellenv)"
I just commented out the first line which doesn't actually have the </opt/> in the address. It's asking for a $opt, and then the address. So commenting out that line removed the location error and just read the correct line. So it doesn't show the error anymore when opening the terminal.
