问题描述

我正在运行Mac OS X 10.9.1,我正在使用RVM来管理Ruby v2.0.0-p353。

I am running Mac OSX 10.9.1 and I am using RVM to manage Ruby v2.0.0-p353.

当我尝试安装Rails时,出现此错误:

When I try to install Rails I get this error:

Ryans-MacBook-Air-2:~ ryan$ gem install rails
ERROR:  Error installing rails:
invalid gem: package is corrupt, exception while verifying: undefined method`path2class' for #<Psych::ClassLoader:0x0000010c9d0be0> (NoMethodError) in /Users/ryan/.rvm/gems/ruby-2.0.0-p353/cache/i18n-0.6.9.gem

以下是我已安装的宝石列表:

Here is a list of gems I have installed:

Ryans-MacBook-Air-2:~ ryan$ gem list

*** LOCAL GEMS ***

bigdecimal (1.2.3, 1.2.0)
bundler (1.5.1)
bundler-unload (1.0.2)
executable-hooks (1.2.6)
gem-wrappers (1.2.1)
io-console (0.4.2)
json (1.8.1, 1.7.7)
minitest (5.2.0, 4.3.2)
psych (2.0.2, 2.0.0)
rake (10.1.1, 0.9.6)
rdoc (4.1.0, 4.0.0)
rubygems-bundler (1.4.2)
rvm (1.11.3.8)
test-unit (2.5.5, 2.0.0.0)

有没有人有解决此问题的建议?

Does anyone have suggestions to fix this?

推荐答案

最新版本不再有 class2path 可以通过将Psych gem降级到2.0.0来避免:

The latest version no longer has the class2path method so the problem can be avoided by downgrading the Psych gem to version 2.0.0:

gem list psych   # note down latest version
gem uninstall psych -v 2.0.5  # or whatever version you have installed

可以在需要时再次升级心灵宝石。

After the gems are installed you can upgrade the Psych gem again should you need it.
