RubyMineIDE中包的ruby方法的下拉列表？

通常，IDE中的下拉列表是在导入包并键入其名称后按tab键显示的，但不是RubyMine。我开了Vim仿真。我打开了交互式RubyShell

irb

，但无法为包的方法实现自动完成

RubyMine中的自动完成功能是如何工作的，以及如何列出OAuth等包的方法？

---

RubyMine自动补全功能主要通过填写项目中使用的名称和关键字来实现。有关如何实现的详细信息，请参阅。还有一个问题可能会提供一些关于RubyMine如何完成的清晰信息

至于在包中列出可用方法的问题（实际上是在任何对象中）。可以使用方法

.methods

获取对象响应的方法数组由于ruby的动态特性和可能的实现

方法\u缺失

，列表可能不包含所有可能的方法

这里有一个例子

"string".methods
