Segmentation fault

[ghost]

First of all, thank you for that great tool. It is one of the few things which made my experience with OSX very pleasurable.

Recently I stumbled upon some nusty bug (segmentation fault), which prevents me to use your awesome package manager further. I already tried doctor and update commands, as well as reinstalling. Also tried different Ruby versions, but to no avail. Below I pasted what terminal returned (unfortunately no logs had been produced). Version of OSX: 10.12.1 (Sierra) Ruby: 2.3.1 (but tried also with 2.2.x, and 2.0.0).

/Users/pszek/.gem/ruby/2.0.0/gems/json-1.8.3/lib/json/ext/parser.bundle: [BUG] Segmentation fault
ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin16]

[MikeMcQuaid]

Sorry but you have not followed the requested steps on the Troubleshooting page

Please follow (all of) these steps and post the information here so we can help you with your problem.

Thanks!

[ghost]

OK, switching to NIX

[MikeMcQuaid]

Because you won't provide us with the information we need to fix your issue? Wow.

[MikeMcQuaid]

No, because I wanted to help (I don't care about bleeding edge packages, I have already everything what I need - just interface not working properly). Maybe someone else would have the same problem and this would be useful.

It's not useful if no-one provides us the information we need.

But you rejected it with cold blooded bureaucracy manner.

I didn't reject anything. I asked you to follow that because I need information provided from that (specifically brew config output) to help debug and triage this issue.

You asked us for our help and then insult us. That's not an appropriate way to behave towards people who supply you with a free tool.

[MikeMcQuaid]

@Pszek humbly apologised in #1627 so going to continue helping here.

From #1627 it seems you're saying brew config also causes a segfault. Running gem uninstall json should fix this for you; you don't need it as a separate gem as it's included into Ruby 2 and the extension seems to be broken. If that fails, try gem uninstall --user json. If that still fails: post the failing gem messages in here and we'll try another approach.

[ghost]

@Thank you!

Both commands give me:

ERROR:  While executing gem ... (Gem::InstallError)
    gem "json" cannot be uninstalled because it is a default gem

If I understood correctly, I should removed these gems globally?

[MikeMcQuaid]

Try /usr/bin/gem uninstall --user json. If that still fails then try to manually rm -rf /Users/pszek/.gem/ruby/2.0.0/gems/json-1.8.3/.

[ghost]

Thank You! That nailed it:

/usr/bin/gem uninstall --user json

Remember, the beer offer is still valid. I can send you some craft if you like.

[MikeMcQuaid]

I appreciate the offer. We'd love any donations you or anyone you know can give: https://github.com/Homebrew/brew#donations

Glad it got fixed.
