Cannot install mailcatcher gem about brew-gem HOT 4 CLOSED

We've had some gems that suddenly don't install on high sierra either and I haven't tracked down the exact cause of the problem. If you want to troubleshoot further, I'd suggest running brew gem formula mailcatcher > mailcatcher.rb and playing around with the resulting formula in mailcatcher.rb. I suspect something to do with the way we are overriding GEM_HOME in the formula may be part of the cause.

I was able to fix the issue by replacing the initialization of the gem paths in the generated bin:

I replaced this:

ENV['GEM_HOME']="/usr/local/Cellar/gem-mailcatcher/0.6.5"
ENV['GEM_PATH']="/usr/local/Cellar/gem-mailcatcher/0.6.5"

with this:

Gem.paths = {
  'GEM_HOME' => "/usr/local/Cellar/gem-mailcatcher/0.6.5",
  'GEM_PATH' => "/usr/local/Cellar/gem-mailcatcher/0.6.5"
}

And now it works for me. I found Gem.paths= by googling a bit around (from https://stackoverflow.com/a/30369485/891458), but haven't looked into it further. Maybe it makes sense to use it generally?

Ah! I didn't realize that mailcatcher installed but the binstub wasn't working. For that, you might try #49.

Ok, just tested it, #49 also fixes the problem. Closing this 👍
