Verification

• My "brew doctor output" says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.
• I searched for recent similar issues at https://github.com/Homebrew/homebrew-core/issues?q=is%3Aissue and found no duplicates.

What were you trying to do (and why)?

Use corepack, which per Node documentation is supposed to be part of all recent Node releases. See https://nodejs.org/api/corepack.html. (Note that it is listed as "experimental," but in the usual Node meaning that wouldn't typically prevent it from being part of a build.)

As to why, because I'm trying to follow the build instructions for a different project (Pulsar, https://pulsar-edit.dev/docs/launch-manual/sections/core-hacking/#building-pulsar).

What happened (include all command output)?

What did you expect to happen?

$ which corepack
/opt/homebrew/bin/corepack
$

Step-by-step reproduction instructions (by running brew commands)

• brew upgrade node

or

• brew install node if you don't already have it installed.

Did you try brew install corepack? https://formulae.brew.sh/formula/corepack#default

We keep corepack fully up-to-date as separate formula and have disabled copy in node formula

homebrew-core/Formula/n/node.rb

Line 75 in c887180

--without-corepack

(also see discussion at #91540)

Homebrew's older Nodes do include corepack probably to guarantee a compatible version,

❯ brew which-formula corepack
corepack
node@14
node@16
node@18

@cho-m Thanks for the pointer. I missed that corepack was bundled separately.
