我已经将Aptana作为Eclipse插件（全新安装）进行了全新安装。在Eclipse上使用Aptana时Ruby的内容协助失败
我怀疑这可能是一个重复的键绑定（很可能是一个bug），但在线信息是稀疏的。
- 的Eclipse：3.5.2-8ubuntu3
- 集锦：3.0.5.201110061700-7
- 的Ubuntu 11.04，内核2.6.38-11-通用
会话数据：
- eclipse.buildId = M20100211-1343
- java.version = 1.6.0_22
- java.vendor = Sun Microsystems公司
- BootLoader的常数：OS = Linux中，ARCH = x86_64的，WS = GTK，NL = en_NZ
- 命令行参数：-OS Linux的-ws GTK -arch x86_64的
对于Python脚本，这通常看起来好（现在）。 我开始使用一个新的Ruby脚本，定义一个对象后跟一个“。”。 &尝试调用内容通过带有以下弹出错误Ctrl +空格键击&帮助：提供
"Content Assist" did not complete normally. Please see the log for more information.
