Description of issue

I can't seem to get mtr to run, with . I ran doctor and installed the new CLI tools as they were out of date. I also had the below error which I ran the remove command for:

Warning: You have an unnecessary local Core tap!
This can cause problems installing up-to-date formulae.
Please remove it by running:
brew untap homebrew/core

I've tried reinstalling mtr multiple times.

My preferred shell is bash as that is what I am used to.

Can I get some help please?

[SMillerDev]

What does brew ls mtr say?

[urbanracer34]

Contents below:

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

[SMillerDev]

Do you have a ~/.bash_profile?

[urbanracer34]

Yes I do but it is just an alias to ssh to a server which no longer exists.

[SMillerDev]

Try putting the export PATH="/usr/local/sbin:$PATH" line in there.

[urbanracer34]

That worked! Thank you so much for the help!

[gromgit]

Closed out of terminal and reopened. Failed to run the app again. I'm back at square one!

Since brew config says you're running macOS, that export line (and there should only be one line) probably needs to be in ~/.bash_profile instead of ~/.bashrc, because the Terminal app you're running defaults to launching bash as an interactive login shell.

[urbanracer34]

@gromgit @SMillerDev gave me all the info I needed to make it work.

[urbanracer34]

My problem has been solved.

Good day,

I’m also experiencing issues with mtr. Entering PATH=$PATH:/opt/homebrew/sbin in the terminal is the only way I’ve found to make mtr work. However, it stops working every time I close and reopen the terminal. This has been a recurring issue over the past few months, and I’m hoping someone can suggest a permanent solution.

I also get the following with brew doctor:

Warning: Homebrew's "sbin" was not found in your PATH but you have installed
formulae that put executables in /opt/homebrew/sbin.
Consider setting your PATH for example like so:
echo 'export PATH="/opt/homebrew/sbin:$PATH"' >> ~/.zshrc

I have found that echo 'export PATH="/opt/homebrew/sbin:$PATH"' >> ~/.zshrc does not do anything if I run it in my terminal.

Please let me know if you need any more information from my side—or if I’m simply overlooking something obvious.

[AndreRoode]

Thank you,
Will you be able to help me look for what is causing this as I am not sure what PATH will be correct and what will be wrong.

[gromgit]

You'll have to upload the trace.log file to this thread.

[AndreRoode]

Thank you
trace.log

[gromgit]

Yup, you have a problem:

+/Users/andreroode/.zprofile:1> /opt/homebrew/bin/brew shellenv
+/Users/andreroode/.zprofile:1> eval export 'HOMEBREW_PREFIX="/opt/homebrew";' export 'HOMEBREW_CELLAR="/opt/homebrew/Cellar";' export 'HOMEBREW_REPOSITORY="/opt/homebrew";' 'fpath[1,0]="/opt/homebrew/share/zsh/site-functions";' 'PATH="/opt/homebrew/bin:/opt/homebrew/sbin:/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/local/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/appleinternal/bin:/Applications/VMware' 'Fusion.app/Contents/Public:/Applications/VMware";' export 'PATH;' '[' -z '"${MANPATH-}"' ']' '||' export 'MANPATH=":${MANPATH#:}";' export 'INFOPATH="/opt/homebrew/share/info:${INFOPATH:-}";'

you run brew shellenv as directed in ~/.zprofile line 1, and it Does The Right Thing, adding both /opt/homebrew/bin and /opt/homebrew/sbin (in the order which is generally expected and desired)...

+/Users/andreroode/.zshrc:1> export PATH='/opt/homebrew/sbin:/opt/homebrew/bin:/opt/homebrew/sbin:/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/local/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/appleinternal/bin:/Applications/VMware Fusion.app/Contents/Public:/Applications/VMware'
+/Users/andreroode/.zshrc:2> export PATH=/opt/homebrew/bin:/opt/homebrew/bin:/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/local/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/appleinternal/bin:/Applications/VMware Fusion.app/Contents/Public
/Users/andreroode/.zshrc:export:2: not valid in this context: Fusion.app/Contents/Public

but then you reset your PATH twice in ~/.zshrc, the first of which unnecessarily reverses the order of the Homebrew directories, and the second removes /opt/homebrew/sbin and replaces it with a redundant copy of /opt/homebrew/bin. (The last line I quoted about also indicates a syntax error in line 2, because there's a path component with a space in it, but you forgot to quote the PATH value.)

Unless I missed something, both lines in ~/.zshrc don't add any new PATH components, and are therefore redundant. If you agree, I suggest replacing those two lines with the brew shellenv lines from ~/.zprofile.

[AndreRoode]

Thank you for your assistance. I have made the changes to ~/.zshrc and now mtr is working.
