Scala console won't work, IntelliJ
提问by BogdanC
I did all the preference work, installed scala, everything works except this, i just can not test a scala class in the console window.
我做了所有的偏好工作，安装了 Scala，除此之外一切正常，我只是无法在控制台窗口中测试 Scala 类。
In tutorials I see they just type in something behind the scala> but it just won't work, i can type some random stuff there below which doesn't do anything when I press enter.
在教程中，我看到他们只是在 scala> 后面输入了一些东西，但它不起作用，我可以在下面输入一些随机的东西，当我按下 Enter 键时它不会做任何事情。
Can you guys help me out? I would be very thankful. Cheers
你们能帮我吗？我会很感激的。干杯

Once you type on the Scala console in IntelliJ Community Edition. Hit Ctrl+Enterinstead of enter to execute.
一旦您在 IntelliJ 社区版中的 Scala 控制台上键入。按Ctrl+Enter而不是 Enter 来执行。
took me a while to get around it :)
我花了一段时间来解决它:)

If you want the console to execute when you hit enter, go to Preferences > Keymap > Plug-ins > Scala, and right-click ScalaConsole.Execute. Select Add Bookmarkand hit enter in the first box. Then click Applyand then OK.
如果您希望在按 Enter 键时执行控制台，请转到Preferences > Keymap > Plug-ins > Scala，然后右键单击ScalaConsole.Execute。Add Bookmark在第一个框中选择并按回车键。然后单击Apply，然后单击OK。

You have to press ?-Enter on Mac OS X when you're done typing.
完成输入后，您必须在 Mac OS X 上按 ?-Enter。

I guess it's better to change the message from "Type in expressions to have them evaluated." to "Type in expressions and press Ctrl + Enter to have them evaluated."
我想最好将消息从“输入表达式以对其进行评估”进行更改。到“输入表达式并按 Ctrl + Enter 进行评估。”

Just add scala sources to $PATH and it should be available / callable from CMD / Idea Terminal
只需将 scala 源添加到 $PATH，它应该可以从 CMD/Idea Terminal 获得/调用
