Homebrew installs programs under /usr/local on intel but under /opt/homebrew on arm. So once you've installed Homebrew's zsh, it will be at /opt/homebrew/bin/zsh. The zsh that ships with macOS is at /bin/zsh.
If you've hard-coded the path /usr/local/bin/zsh somewhere, you can use one of the following commands to make that exist:
sudo ln -s /bin/zsh /usr/...
You can easily find out an answer to your question with the command brew info llvm, which will show this:
llvm is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.
If you need to have llvm first in your PATH, run:
echo 'export ...
You have two separate installations of python3 and they know nothing of each other,
One from Apple the original in /usr/bin/python3 the 3.8.9 version
The other via Homebrew (I suspect in /opt/homebrew/python3) the 3.9.9
They know nothing of each other.
pip3 is a script file that is related to the python version it works with - the first line of pip3 is #!&...
This only affects processes launched from your environment and not the system at-large.
homebrew is designed to install on a one-person computer with a user with admin rights. However, when installed, '/usr/local/bin' (on Intel machines) or '/opt/homebrew' on M1 Silicon ones) house the installed software. Since the permissions of these directories and ...
Perhaps I'm missing something, but the issue seems to be stated clearly:
Error: You are using macOS 10.13.
We (and Apple) do not provide support for this old version.
I don't use Homebrew because of philosophical differences :) I use MacPorts instead. I just checked, and they do support High Sierra (10.13) & even much "older" versions (Tiger/...
I also got this message while running brew doctor. It seems ilmbase was previously installed because ImageMagick (among other libraries) relied on it. The ilmbase formula reveals that the ilmbase library has since been renamed/replaced by the OpenEXR library.
If you are getting errors when trying to remove ilmbase or are seeing packages that still rely on it,...

In case anyone else arrives at this issue from a search:
gfx requires both Xcode and the Xcode command line tools. Even if you have the command line tools installed, you still need Xcode.
Xcode is required for the complete macOS SDK (specifically the tools for compiling ...
For recent versions of Homebrew, installed libraries (for example, SDL) will be located in $(brew --prefix)/lib as symlinks. You can update the LIBRARY_PATH variable to use this location like so:
export LIBRARY_PATH="$LIBRARY_PATH:$(brew --prefix)/lib"
The headers files will similarly available in $(brew --prefix)/include so you can add this to ...
