为什么应用程序可以在系统环境中正常运行，但不能在RVM下运行？

Question

我试图得到了RVM加快。

我有一个Rails 2个应用程序，我的系统中正常工作。换句话说，它在我安装RVM之前就工作了，如果我“关闭RVM”与$ rvm use system一起工作。

在RVM我安装在同一红宝石版本和补丁级别为我的系统红宝石，然后我创建了一个宝石，并安装所有的应用程序使用的gem版本。

然而，在RVM当我运行rake gems我得到这样的结果......

$ rake gems 
rake/rdoctask is deprecated. Use rdoc/task instead (in RDoc 2.4.2+) 
rake aborted! 
undefined method `name' for "actionmailer":String 

Tasks: TOP => environment 
(See full trace by running task with --trace) 

随着--trace ...

$ rake gems --trace 
rake/rdoctask is deprecated. Use rdoc/task instead (in RDoc 2.4.2+) 
** Invoke gems (first_time) 
** Invoke gems:base (first_time) 
** Execute gems:base

Answer 1

是的，RubyGems最近有一个非常快速的发展速度，并不完全向后兼容。尝试：

rvm rubygems 1.3.7 

：

gem install rubygems -v 1.3.7 

您可能必须清除出宝石重新安装RubyGems的...

如果你使用RVM，您可以用下面的命令改变了RubyGems的版本
