Installed intellij and added sdk path to project structure, but when i try to run i get:
安装了 intellij 并为项目结构添加了 sdk 路径，但是当我尝试运行时，我得到：
Error: Cannot run program "/home/$USER/java/jdk1.8.0_121/bin/java"
(in directory"/home/$USER/.intelliJIdea2016.3/system/compile-server"):
error=2, No such file or directory
Both files (/home/$USER/java/jdk1.8.0_121/bin/java and /home/$USER/.intelliJIdea2016.3/system/compile-server) exists.
两个文件（/home/$USER/java/jdk1.8.0_121/bin/java 和/home/$USER/.intelliJIdea2016.3/system/compile-server）都存在。

从这里的答案Change jdk path in IntelliJ 13 whencompile from 32 bit program file folder to 64 bit onework for me
From the menu: File-> Project Structure....
从菜单中：File-> Project Structure...。
On the left, below "Platform Settings", you have "SDKs": click on it; you can add your new JDK here.
在左侧，“平台设置”下方，您有“SDK”：单击它；您可以在此处添加新的 JDK。
Always in the same window, below "Project Settings", select "Project": you have the option to select the JDK which you just added.
始终在同一窗口中，在“项目设置”下方，选择“项目”：您可以选择刚刚添加的 JDK。

In my case, IntelliJ was pointing to a JDK folder of a version I had uninstalled. For some reason the uninstaller didnt remove the Java/jdk* folder, so it was not showing any error in the configuration screen File -> Project Structure -> SDK
就我而言，IntelliJ 指向我已卸载版本的 JDK 文件夹。由于某种原因，卸载程序没有删除 Java/jdk* 文件夹，因此在配置屏幕 File -> Project Structure -> SDK 中没有显示任何错误
After finding out it was pointing to an uninstalled JDK folder then I proceeded to adjust this configuration thanks to the answer posted by UberHans
在发现它指向一个已卸载的 JDK 文件夹后，由于 UberHans 发布的答案，我继续调整此配置

Make sure your JDK path is correct. In my case, it updated JDK version somehow but I didn't notice it, there are a lot of red underlines. After I edit JDK with the correct path, the world became green.
确保您的 JDK 路径正确。就我而言，它以某种方式更新了 JDK 版本，但我没有注意到，有很多红色下划线。用正确的路径编辑JDK后，世界变绿了。
