cannot gem install after the latest Command Line Tools 6.3 update

[brentredd]

Running Ruby 2.2.1 and OS X 10.10.3. The latest Command Line Tools update appears to break therubyracer or libv8. This might actually be a bug with Command Line Tools 6.3 and not therubyracer. I've tried uninstalling libv8 (3.16.14.7 x86_64-darwin-14) and reinstaling using --with-system-v8 and also deleting my Gemfile.lock and running bundle. When I run gem install therubyracer -v '0.12.2' I get:

Downgrading Command Line Tools to 6.2 works for now until this gets resolved (I'm guessing by Apple):

1. go to https://developer.apple.com/downloads/index.action
2. download "Command Line Tools (OS X 10.10) for Xcode - Xcode 6.2"
3. gem install therubyracer -v '0.12.2'

Searching for the error message on Google yields results that lead me to believe that it indeed is a bug in the development environment provided by Apple. Thank you for the heads up

This was the only way to install this gem for me as well. :disappointed:

[cowboyd]

Yes, this is a bug in the Command Line Tools distributed by Apple.

Until they release an official fix, the recommended course of action is to manually install version 6.2

[irealva]

Thanks! Reverting to version 6.2 solved it for me.

[akiynkmr]

Thank you for this solution!

[sodabrew]

The official fix is Xcode 6.3.1 and/or Command Line Tools 6.3 with release date of Apr 21, 2015. The original buggy CLT 6.3 was released on Apr 9, 2015.

I just installed Command Line Tools 6.4 on 10.10.4, but I cannot install therubyracer 0.12.2. Initially both libv8 and therubyracer failed to install, but I reinstalled ruby 2.0.0-p353 and now libv8 3.16.14.8 installs with no problems but therubyracer still fails. The error does not look the same as reddshack but thought I would ask here since the new tools did not appear to totally solve my problem.

Error message from bundle install:

Please open a new issue for a new issue.

[cmthakur]

facing same issue as reported by @phyzzld,

[brentredd]

wait for the new version of libv8 or build the gem yourself with rake https://github.com/cowboyd/libv8/pull/177

[cmthakur]

After updating my command line to 6.4 and then performing brew upgrade, the problem got resolved.

[boilsquid]

can confirm updating command line tools to 6.4 and performing brew update, does solve this problem.

[sodabrew]

Thank you all for reporting back that Command Line Tools 6.4 works.
