无法在干净安装Yosemite和干净版本的红宝石上安装therubyracer

Question

有很多人有类似的问题,我过去曾经在其他机器上遇到其中一个并且没有一个解决方案似乎有效 - 我似乎也有比其他有类似问题的人有不同的错误:

Building native extensions.  This could take a while...
ERROR:  Error installing therubyracer:
    ERROR: Failed to build gem native extension.

Gem files will remain installed in /Users/ecnalyr/.rvm/gems/ruby-2.0.0-p353@canopy/gems/therubyracer-0.12.2 for inspection.
Results logged to /Users/ecnalyr/.rvm/gems/ruby-2.0.0-p353@canopy/extensions/x86_64-darwin-14/2.0.0/therubyracer-0.12.2/gem_make.out

运行时:

gem install therubyracer -v '0.12.2'

或者干脆

bundle install

与therubyracer包括在我的Gemfile.

我正在运行Yosemite 10.10.3,Ruby 2.0.0-p353,我已经卸载了所有内容并尝试gem install libv8 -- --with-system-v8了经常出现这些问题的解决方案,但是没有找到解决方案.

创建一个临时文件'__debug'为我解决了这个问题.

在终端中运行此命令:

echo'#define _LIBCPP_ASSERT(x,m)((void)0)'| sudo tee -a/Library/Developer/CommandLineTools/usr/include/c ++/v1/__ debug>/dev/null

我能够通过重新安装XCode 6.2的命令行工具(而不是XCode 6.3的命令行工具)来解决这个问题.
