Eclipse + Apatna 插件：无法调试

Eclipse + Apatna plug-in: unable to debug

你能帮我解决为 Ruby 组织任何 IDE 的问题，以便我可以调试我的脚本。

我选择了Eclipse+Aptana插件。但这不是教条。如果有更简单的方法，我肯定会更改 IDE 和插件或任何东西。

好吧，让我们 return 了解我现在所拥有的。 我的普通用户下好像安装不了ruby-debug-ide。 在root用户下我可以执行gem install ruby-debug-ide。我可以在 gem list --local 中看到 ruby-debug-ide。 但仅当我以 root 用户身份登录时。 以下留言均为普通用户。

我现在拥有的：

当我在 Eclipse 中尝试将我的应用程序调试为 ruby 应用程序时，我得到：

/home/michael/.rvm/rubies/ruby-2.2.3/lib/ruby/site_ruby/2.2.0/rubygems/dependency.rb:315:in to_specs': Could not find 'ruby-debug-ide' (>= 0) among 23 total gem(s) (Gem::LoadError) Checked in 'GEM_PATH=/home/michael/.rvm/gems/ruby-2.2.3:/home/michael/.rvm/gems/ruby-2.2.3@global', executegem envfor more information from /home/michael/.rvm/rubies/ruby-2.2.3/lib/ruby/site_ruby/2.2.0/rubygems/dependency.rb:324:in to_spec' from /home/michael/.rvm/rubies/ruby-2.2.3/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_gem.rb:64:in gem' from /usr/local/bin/rdebug-ide:22:in'

当我 运行 gem env:
