ruby-on-rails - 如何解决 RubyMine "' ruby​​-debug-ide' isn't installed”错误

Question

我得到错误:

Cannot start debugger. Gem 'ruby-debug-ide' isn't installed or its executable script 'rdebug-ide' doesn't exist.

但所有 gem 都已成功安装:

gem 'ruby-debug-ide'
gem 'debase'

我可以手动运行“rdebug-ide”:

$ rdebug-ide
Using ruby-debug-base 0.2.1
Usage: rdebug-ide is supposed to be called from RDT, NetBeans, RubyMine, or
       the IntelliJ IDEA Ruby plugin.  The command line interface to
       ruby-debug is rdebug.

但是当我开始调试时，RubyMine 要求安装 ruby​​-debug-ide gem。为什么？

并且，在安装之后我得到:

Cannot start debugger. Gem 'ruby-debug-ide' isn't installed or its executable script 'rdebug-ide' doesn't exist.

我运行的是 Mac OS X 10.11.3。

这是对我有用的实际命令:

gem install ruby-debug-ide --pre
