Mac M1 Warning: /opt/homebrew/bin is not in your PATH.

[JasonNewton1]

Hello,

I am a beginner and I am trying to install Homebrew on my M1 Mac mini.

The installation went okay but I had the following appear at the end of the installation.

Warning: /opt/homebrew/bin is not in your PATH. Add Homebrew to your PATH in /Users/jasonnewton/ .zprofile: echo ' eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/jasonnewton/ .zprofile eval $(/opt/homebrew/bin/brew shellenv) Run 'brew help' to get started

My question is where is this file, how do I edit it and what do I actually insert into the file?

Kind Regards

[carlocab]

.zprofile, if it exists, is in /Users/jasonnewton. You need to insert eval $(/opt/homebrew/bin/brew shellenv) into .zprofile.

You can do this by running

echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/jasonnewton/.zprofile

[unlimitlessY]

finally found the answer.......
however when i run this code correctly
this happend ：-bash: /Users/Alex: Permission denied

how should i fix it

[LeonorMalaga]

You need to add the PATH by type :

#export PATH=$PATH:/opt/homebrew/bin

This works for me

[SMillerDev]

That's terrible advice, nothing in Homebrew needs root unless it's explicitly announced. Definitely setting shell variables does not require root.

[LeonorMalaga]

You are right

[haliteris]

After using : echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/jasonnewton/.zprofile

I checked if I passed it to my path: echo $PATH

Then I saw in the first line: /opt/homebrew/bin:/opt/homebrew/sbin:

Then It worked.

Hello, have some problem…

I did this

    echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/homefolder/.zprofile
    eval $(/opt/homebrew/bin/brew shellenv)

.zprofile

All works

Then I restart my Terminal
`zsh: command not found: brew

I can write it* and all will be ok but I need do it always when I open my terminal app, how to fix it?

Move this line:

eval $(/opt/homebrew/bin/brew shellenv)

after

export PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"

Alternatively, just delete/comment export PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin" as I don't think you need that line at all.

[warb2n]

finally I delete this* from .zshrc

• eval $(/opt/homebrew/bin/brew shellenv)
  And add it at the end
  echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> $HOME/.zshrc
  and all works

Thank you all, peace

[carlocab]

I would also delete or comment

export PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"

as there's no reason to have this line here, and can cause hard-to-diagnose breakage.

@gromgit Good call on logging out and in again to update the .zprofile.

• After updating my new macbook air M1's OS to Big Sur 11.3.1, I installed homebrew natively (wiithout rosetta 2).
• And then it asked to add brew to the path variables. I did the echo and eval commands that @carlocab initially recommended.
• Then I logged out and logged back in to update the .zprofile per @gromgit suggestion.

Then I tested brew out by installing the github CLI.

Thanks all! 🤙

What worked for me was adjusting my PATH variable in the ~/.zshrc file. I found that one of the paths listed earlier on was pointing to Python 2.7. Once I exported a version of PATH removing that, restarted the zshell and then opened a new tmux session, I ran python -V and the version was fixed.

[Chhe-chinyong]

Solved by added to .zprofile

echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/macbookpro/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"eval "$(/opt/homebrew/bin/brew shellenv)"

the path of might change a bit depend on computer path, so please copy your own error missing path

[seandenigris]

I added eval "$(/opt/homebrew/bin/brew shellenv)" to .zprofile by copy/pasting the command suggested by the brew install, and the line did indeed show up in the file, but I still got zsh: command not found: brew. When I added the same line to zshrc (which formerly didn't exist), zsh was able to find the command.

[fatso83]

That's purely because of how the shell operates. The profile is read once - on login. Bashrc is read every time you open a new terminal.

If you had logged out and in this would not have been an issue.

[zcbtmjc]

Can someone please help me? I am trying to install python3, and have to install something called home-brew. Im totally new to terminal and have no real clue what's going on.

As you can see terminal has now explained I need to install some kind of path? for which I just copy and pasted the following:

echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/user/.profile

eval "$(/opt/homebrew/bin/brew shellenv)"

But as you can see, nothing has happened? What do I need to do? what am I doing wrong?!?

[gromgit]

When you run which brew, what does it say? If it says /opt/homebrew/bin/brew, your setup is done.

[vaniadimova]

I get /usr/local/bin/brew which means it is on PATH

[AbangkuOfficial]

great its work

For me writing into .zshrc file worked https://superuser.com/questions/1621771/brew-command-not-found-after-installing-homebrew-on-an-arm-m1-mac

[JagadishSivakumar]

Hello, when I was trying to install TensorFlow for mac m1. I faced a similar issue, this is because the binaries are not included in the 'PATH' environment variable.

• A temporary fix is by setting the PATH variable using export command.
  export PATH=/opt/homebrew/bin:$PATH

• A permanent fix is by editing either the bash or zprofile files, whichever is used.
  vi ~/.bashrc - for bash shell if its not present then,

vi ~/.zprofile - to access the z-shell, in this file add export PATH="/opt/homebrew/bin:$PATH" and then save it.

• To implement the changes run source ~/.zprofile and then print by echo $PATH. I was able to view the updated PATH variable.

Hope this works :)

[SMillerDev]

The real solution is the one marked as answered. This fix will only resolve part of the problem.

[JagadishSivakumar]

Hi @SMillerDev ,

Editing the PATH in zprofile, permanently solved the issue. Just shared a way that worked for me.
