安装rubyracer时出错,错误"gem gem:package is corrupt"

Question

尝试在OSX 10.9上安装therubyracer时,使用以下命令:

$ gem install therubyracer -v '0.12.0'

我收到错误:

ERROR:  Error installing therubyracer:
    invalid gem: package is corrupt, exception while verifying: undefined method `path2class' for #<Psych::ClassLoader:0x000001018cf210> (NoMethodError) in /Users/doved/.rvm/gems/ruby-2.0.0-p353/cache/therubyracer-0.12.0.gem

安装了XCode开发人员工具,我尝试删除缓存文件,但我仍然收到错误.

Answer 1

删除/Users/doved/.rvm/gems/ruby-2.0.0-p353/cache/therubyracer-0.12.0.gem并再次安装gem.RubyGems没有正确下载文件,系统正确报告gem已损坏.
