在 OS X 10.9 (Mavericks) 上安装 Java

Installing Java on OS X 10.9 (Mavericks)

提问by user2909913

I have installed the JDKon Mac OS X v10.8(Mountain Lion). When I upgraded it to Mac OS X v10.9(Mavericks) and ran java -versionin the terminal, it showed:

我已经在Mac OS X v10.8(Mountain Lion)上安装了JDK。当我将其升级到Mac OS X v10.9(Mavericks) 并在终端中运行时，它显示：java -version

No Java runtime present, requesting install.

不存在 Java 运行时，请求安装。

Then I manually installed the JDK (1.7) on my Mac. It seems that the installation worked fine. When the installation was done, I opened the terminal and typed java -versionas well. It also showed the same error:

然后我在我的 Mac 上手动安装了 JDK (1.7)。似乎安装工作正常。安装完成后，我打开终端并输入java -version。它也显示了同样的错误：

No Java runtime present, requesting install.

不存在 Java 运行时，请求安装。

How can I solve this problem?

The new Mavericks(10.9) showed me the "Requesting install", but nothing happened.

新的小牛队(10.9) 向我展示了“请求安装”，但什么也没发生。

The solution was to manually download and install the official Java package for OS X, which is in Java for OS X 2013-005.

解决方案是手动下载并安装 OS X 的官方 Java 包，该包位于 适用于 OS X 的 Java 2013-005.

Update:As mentioned in the comments below, there is a newer version of this same package:

更新：正如在下面的评论中提到的，这个包有一个更新的版本：

Java for OS X 2014-001

适用于 OS X 的 Java 2014-001

Java for OS X 2014-001(Correcting dead line above)

Java for OS X 2014-001（更正上面的死线）

Java for OS X 2014-001 includes installation improvements, and supersedes all previous versions of Java for OS X. This package installs the same version of Java 6 included in Java for OS X 2013-005.

适用于 OS X 2014-001 的 Java 包括安装改进，并取代适用于 OS X 的所有先前版本的 Java。此软件包安装与适用于 OS X 2013-005 的 Java 中包含的相同版本的 Java 6。

There isn't any need to install the JDK, which is the developer kit, just the JREwhich is the runtime environment.

没有任何需要安装JDK，这是开发人员工具包，只是JRE这是运行环境。

I downloaded manually to here: Java for OS X 2014-001.

我手动下载到这里：Java for OS X 2014-001。

After that open your terminal and check the installation with java -version.

之后打开您的终端并使用java -version.

The OP implied that Java 7 was the need. And Java 6 is in fact no longer being 'supported' so 7 is the version you should be installing at this point unless you have legacy app concerns.

OP 暗示需要 Java 7。并且 Java 6 实际上不再受“支持”，因此 7 是您此时应该安装的版本，除非您有遗留应用程序的问题。

If you only want to install the latest official JRE from Oracle, you can get it there, install it, and export the new JAVA_HOME in the terminal.

如果您只想从 Oracle 安装最新的官方 JRE，您可以在那里获取并安装它，然后在终端中导出新的 JAVA_HOME。

• Open your Terminal
• java -versiongives you an error and a popup
• Get the JRE dmg on http://www.oracle.com/technetwork/java/javase/downloads/index.html
• Install it
• In your terminal, type: export JAVA_HOME="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home"
• java -versionnow gives you java version "1.7.0_45"

• 打开你的终端
• java -version给你一个错误和一个弹出窗口
• 在http://www.oracle.com/technetwork/java/javase/downloads/index.html上获取 JRE dmg
• 安装它
• 在您的终端中，键入： export JAVA_HOME="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home"
• java -version现在给你 java version "1.7.0_45"

That's the cleanest way I found to install the latest JRE.

这是我发现安装最新 JRE 的最干净的方法。

You can add the export JAVA_HOMEline in your .bashrcto have javapermanently in your Terminal:

您可以添加export JAVA_HOME在您的生产线.bashrc有java在终端永久：

echo export JAVA_HOME=\"/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home\" >> ~/.bashrc

I downloaded and installed the JDK 1.7 from Oracle. In the console / in TerminalJava 7 works fine.

我从Oracle下载并安装了 JDK 1.7 。在控制台中/在终端Java 7 中工作正常。

When I start a Java program (like Eclipse) via the GUI, I get:

当我通过 GUI启动 Java 程序（如Eclipse）时，我得到：

To open "Eclipse.app" you need a Java SE 6 runtime. Would you like to install one now?

要打开“Eclipse.app”，您需要一个 Java SE 6 运行时。你想现在安装一个吗？

Because I did not want to install old Java version, I used the following workaround:

因为我不想安装旧的 Java 版本，所以我使用了以下解决方法：

sudo ln -nsf /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK

sudo ln -nsf /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK

The right place to download the JDK for Java 7 is Java SE Downloads.

下载 Java 7 JDK 的正确位置是Java SE 下载。

All the other links provided above, as far as I can tell, either provide the JRE or Java 6 downloads (incidentally, if you want to run Eclipseor other IDEs, like IntelliJ IDEA, you will need the JDK, notthe JRE).

所有其他链接上面提供的，据我所知，无论是提供JRE或Java 6次的下载（顺便说一句，如果你想运行的Eclipse或其他IDE，如IntelliJ IDEA的，你需要的JDK，不是在JRE）。

Regarding IntelliJ IDEA - that will still ask you to install Java 6 as it apparently needs an older class loader or something: just follow the instructions when the dialog pop-up appears and it will install the JDK 6 in the right place.

关于 IntelliJ IDEA - 它仍然会要求您安装 Java 6，因为它显然需要一个较旧的类加载器或其他东西：只需在弹出对话框时按照说明进行操作，它就会在正确的位置安装 JDK 6。

Afterwards, you will need to do the sudo ln -snfmentioned in the answer above:

之后，您需要执行sudo ln -snf上面答案中提到的操作：

sudo ln -nsf /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents \
    /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK

(copied here as it was mentioned that "above" may eventually not make sense as answers are re-sorted).

（复制到这里，因为提到“上面”可能最终没有意义，因为答案被重新排序）。

I also set my JAVA_HOMEto point to where jdk_1.7.0_xx.jdkwas installed:

我还设置JAVA_HOME了指向jdk_1.7.0_xx.jdk安装位置：

export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home"

Then add that to your PATH:

然后将其添加到您的PATH：

export PATH=$JAVA_HOME/bin:$PATH

The alternative is to fuzz around with Apple's insane maze of hyperlinks, but honestly life is too short to bother.

This error happens because the plist file of IntelliJ IDEA requires Java version 1.6*. To solve this problem, replace the 1.6* with 1.8*.
