What were you trying to do (and why)?

I was trying to run brew audit [some random formula] and got Error: cannot load such file -- lint_roller/context message.

What happened (include all command output)?

$ brew audit curl
Error: cannot load such file -- lint_roller/context

The same happens with all other formulae and casks. Adding/removing flags doesn't help, f.e.:

$ brew audit --strict rust

What did you expect to happen?

I expected this command to work as usual (i.e. either exit with 0 or print what is wrong with a formula)

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

$ brew audit curl
# Not sure if it can be reproduced or just an issue on my device
# Maybe there is a solution to this problem but I couldn't find anything neither on github issues nor the internet

Not sure if it can be reproduced or just an issue on my device

I can't reproduce this but: we should still have better handling of cases like this as it's pretty hard to debug otherwise. Thanks for the report!

For some reason vendored gem lint_roller didn't have context.rb file:

$ brew ruby -e 'require "lint_roller/context"; puts "no errors"'

<internal:/opt/homebrew/Library/Homebrew/vendor/portable-ruby/3.3.7/lib/ruby/3.3.0/rubygems/core_ext/kernel_require.rb>:37:in `require': cannot load such file -- lint_roller/context (LoadError)
        from <internal:/opt/homebrew/Library/Homebrew/vendor/portable-ruby/3.3.7/lib/ruby/3.3.0/rubygems/core_ext/kernel_require.rb>:37:in `require'
        from -e:1:in `<main>'

brew vendor-gems fixed the issue:

$ brew ruby -e 'require "lint_roller/context"; puts "no errors"'

no errors
