Since it sounds like your JAVA_HOME variable is not set correctly, follow the instructions for setting that.
由于听起来您的 JAVA_HOME 变量设置不正确，请按照说明进行设置。
Setting JAVA_HOME environment variable on MAC OSX 10.9
在 MAC OSX 10.9 上设置 JAVA_HOME 环境变量
I would imagine once you set this, it will stop complaining.
我想一旦你设置了这个，它就会停止抱怨。

In newer versions of OS X (especially Yosemite, EL Capitan), Apple has removed Java support for security reasons. To fix this you have to do the following.
在较新版本的 OS X（尤其是 Yosemite、EL Capitan）中，出于安全原因，Apple 已取消对 Java 的支持。要解决此问题，您必须执行以下操作。
- Download Java for OS X 2015-001 from this link: https://support.apple.com/kb/dl1572?locale=en_US
Mount the disk image file and install Java 6 runtime for OS X.
After this you should not be seeing any of the below messages:
- Unable to find any JVMs matching version "(null)"
- No Java runtime present, try --request to install.
This should resolve the issue for the pop-up shown below:
- 从此链接下载适用于 OS X 2015-001 的 Java：https: //support.apple.com/kb/dl1572?locale =en_US
挂载磁盘映像文件并为 OS X 安装 Java 6 运行时。
在此之后，您不应看到以下任何消息：
- 无法找到任何与版本“(null)”匹配的 JVM
- 不存在 Java 运行时，请尝试 --request 安装。
这应该可以解决下面显示的弹出窗口的问题：

I didn't need the full JDK, I just needed to make JRE work and none of the other answers provided above worked for me. Maybe it used to work, but now (1st Jul 2018) it isn't working. I just kept getting the error and the pop-up.
我不需要完整的 JDK，我只需要让 JRE 工作，上面提供的其他答案都不适合我。也许它曾经有效，但现在（2018 年 7 月 1 日）它不起作用。我只是不断收到错误和弹出窗口。
I eventually solved this issue by placing the following JAVA_HOME export in ~/.bash_profile:
我最终通过在 ~/.bash_profile 中放置以下 JAVA_HOME 导出解决了这个问题：
export JAVA_HOME=/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
Hope this helps someone. I'm running Mac OS High Sierra.
希望这可以帮助某人。我正在运行 Mac OS High Sierra。
