IntelliJ IDEA "The selected directory is not a valid home for JDK"
提问by Maurdekye
I just installed IntelliJ IDEA and I'm trying to set it up. I've gotten to the part where I need to select my home directory for my JDK.
我刚刚安装了 IntelliJ IDEA，我正在尝试设置它。我已经到了需要为我的 JDK 选择主目录的部分。
I tried navigating to my Java installation, C:\Program Files (x86)\Java, and clicked okay but it told me the message above. So, I tried C:\Program Files (x86)\Java\jre7and that didn't work either.
我尝试导航到我的 Java 安装，C:\Program Files (x86)\Java然后单击 OK，但它告诉我上面的消息。所以，我试过了C:\Program Files (x86)\Java\jre7，也没有奏效。
I tried reinstalling the latest JDK (from here) and I still couldn't choose my JDK. I even dragged the .jarinstaller I got from the website and the file selector window wouldn't recognize it.
我尝试重新安装最新的 JDK（从这里），但仍然无法选择我的 JDK。我什至拖动.jar了从网站上获得的安装程序，但文件选择器窗口无法识别它。
I'm at a standstill and I don't know what to do.
我处于停滞状态，我不知道该怎么办。

Because you are choosing jredir. and not JDKdir. JDKdir. is for instance (depending on update and whether it's 64 bit or 32 bit): C:\Program Files (x86)\Java\jdk1.7.0_45In my case it's 32 bit JDK 1.7update 45
因为你选择了jredir。而不是JDK目录。JDK目录 例如（取决于更新以及它是 64 位还是 32 位）：C:\Program Files (x86)\Java\jdk1.7.0_45就我而言，它是 32 位JDK 1.7更新 45

I had the same issue. But I figured it out by choosing this path:
我遇到过同样的问题。但我通过选择这条路径想通了：
First at all, you need to select the C:\folder. Then, you select Program Files. After it, you select java, and finally the jdkyou downloaded. In my case, I downloaded the JDK1.8.0_60 version.
首先，您需要选择C:\文件夹。然后，您选择Program Files。之后，您选择java，最后选择您下载的jdk。就我而言，我下载了 JDK1.8.0_60 版本。
To resume the path:
要恢复路径：
C:\Program Files\java\jdk1.8.0_60
After you are done with it, you can click on the button next. Then you select the create project from templates. This will create a java application with a main() method. After it, you click next to create the name of you project.
完成后，您可以单击下一步按钮。然后您从模板中选择创建项目。这将创建一个带有 main() 方法的 Java 应用程序。之后，单击下一步以创建项目的名称。
I hope this helps you.
我希望这可以帮助你。

It got this error because I had managed to clobber jdk1.8.0_60 with the jre!
之所以出现此错误，是因为我已设法使用 jre 破坏了 jdk1.8.0_60！

This error occurs because if you choosing the path deep in JDK or JRE. The exact path that should be chosen is in my case 64 bit
发生此错误的原因是，如果您选择了 JDK 或 JRE 中的深层路径。应该选择的确切路径在我的情况下是 64 位
C:\Program Files\Java\jdk1.8.0_91
C:\Program Files\Java\jdk1.8.0_91
if 32 bit
如果是 32 位
C:\Program Files (86)\Java\jdk1.8.0_91
C:\Program Files (86)\Java\jdk1.8.0_91

May be your jdk is in /usr/lib/jvm/. This variant for linux.
可能是你的 jdk 在 /usr/lib/jvm/ 中。此变体适用于 linux。

One thing we should note: the jdkshould be installed on C:drive.
我们应该注意的一件事：jdk应该安装在C:驱动器上。
I had JDK installed on my D:drive like this:
我的D:驱动器上安装了 JDK，如下所示：
D:\Program Files\Java\jdk1.8.0_101
And it would still give me the same error. For some reason Java should be installed on C: drive.
它仍然会给我同样的错误。出于某种原因，Java 应该安装在 C: 驱动器上。

In case you missed the configuration at the Project Structure(File -> Project Structure), just reconfigure it like below:

For Windows, apparently the JDK has to be under C:\Program Files.
对于 Windows，显然 JDK 必须在C:\Program Files 下。
This does not work:
这并不起作用：
C:\dev\Java\jdk1.8.0_191
This works:
这有效：
C:\Program Files\Java\jdk1.8.0_191
