Eclipse：找不到 Java 2 运行时环境
我刚刚安装了 Eclipse 3.5。在安装 Android 插件之前，我需要安装 Java jdk，我也这样做了。重新启动后，我无法再启动 Eclipse，因为我收到以下错误：
错误：找不到 Java 2 运行时 环境
奇怪的是，现在我什至无法打开我用于 PHP 编程的其他 Eclipse 安装。有什么建议吗？
更新：
这是我的 eclipse.ini：
<前><代码>-启动 插件/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar --launcher.library 插件/org.eclipse.equinox.launcher.win32.win32.x86_64_1.0.200.v20090519 -showsplash org.eclipse.platform --launcher.XXMaxPermSize 256米 -vmargs -Xms40米 -Xmx256米
I just installed Eclipse 3.5. Before I could install the Android Plugin I needed to install a Java jdk, which I did. After restart Im not able to start Eclipse anymore, because I receive the following error:
Error: could not finde Java 2 Runtime
Environment
The weired thing is, that now I cant even open my other Eclipse Installations, that I use for PHP Programming. Any suggestions?
Update:
This is my eclipse.ini:
-startup plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar --launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.0.200.v20090519 -showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m -vmargs -Xms40m -Xmx256m

您可以通过在 eclipse.ini 中添加以下内容来明确告诉 Eclipse 会话您希望它启动哪个 jdk/jre：
有关如何启动 Eclipse 的更多信息，请参阅此处
You can explicitely tell your eclipse session which jdk/jre you want it to start with adding the following in your eclipse.ini:

我也遇到了类似的问题，只是Java安装成功了。
将 c:/my-path-to-java/jre/bin 添加到 PATH（系统环境变量）后，Eclipse 成功启动。
I had a similar problem, with exception that Java was installed successfully.
Once I added c:/my-path-to-java/jre/bin to PATH (system environment variable), Eclipse started successfully.
将
PATH环境变量从类似更改为类似
Change the
PATHenvironment variable from something liketo something like
从计算机的系统属性环境变量 JAVA_HOME 检查路径变量以获取 jdk 安装的正确路径
Check your path variable from Computer's System Properties Environment Variables JAVA_HOME to ocorrect path to your jdk installation
想知道 Java 安装是否可能已损坏。您可以在“运行”提示符下运行以下命令并将您获得的内容粘贴到代码标签中吗：
Wonder if the Java install might be corrupt. Can you run the following on the Run prompt and paste what you get in code tags:
您的 PHP eclipse 也不会启动，这是有道理的。 Eclipse 本身在 java 上运行。可能是找不到 JRE。
所以我看到两种可能性：
It makes sense that your PHP eclipse won't start either. Eclipse runs on java itself. Probably it cannot find the JRE.
so I see two possibilities:
我有同样的问题。 Eclipse (3.7) 在 JDK 6 上工作了一段时间，然后我安装了 JRE 5（请不要问我为什么）
这个 Eclipse wiki 页面，似乎是最新的，指出：
事实上，我没有更改 JAVA_HOME 所以不可能是这样。
然而，在同一维基页面的底部，有人添加了：
所以我找到了提到的注册表项，它现在的值为“1.5”并将其更改为“1.6”，然后重新启动我的电脑（Windows 7），瞧 - Eclipse 又恢复正常了。
我同意添加“-vm”可能会解决这个问题，尽管它似乎对我不起作用（也许我没有将其添加到正确的位置/格式）。但在我看来，注册表修复对我来说是更好的修复。重新启动计算机并看到 Eclipse 恢复正常后，我卸载了 JRE 5（通过“添加或删除程序”）只是为了解决未解决的问题。
I had the same issue. Eclipse (3.7) worked just fine for a while with JDK 6, and then I installed JRE 5 (please don't ask me why)
This eclipse wiki page, which seems up to date, states that:
And indeed, I did not change JAVA_HOME so that couldn't be it.
However, at the bottom of the same wiki page, someone added:
So I found the mentioned registry entry, which now had the value of "1.5" and changed it to "1.6", then restarted my PC (windows 7), and voila - Eclipse went back alive.
I agree that adding "-vm" might fix this, although it didn't seem to work for me (maybe I didn't add it in the right place/format). But IMO, the registry fix was the better one in my case. After restarting my computer and seeing Eclipse was back to normal, I uninstalled JRE 5 (through "Add or remove programs") just to tie up loose ends.
就我而言，安装最新的 JRE 效果很好： http://www.oracle.com/javase/overview/index.html oracle.com/technetwork/java/javase/overview/index.html
In my case installing the most recent JRE worked well: http://www.oracle.com/technetwork/java/javase/overview/index.html
当我最近安装 JDK 7 Update 9 时，我遇到了同样的问题。我的 eclipse 没有打开，当我从 CMD 运行“java -version”时，它也不起作用。
我将 PATH 变量设置为正确的 bin 目录。
无论如何，最终当我将 JAVA_HOME 设置为新的安装目录时，eclipse 启动正常。不确定 JDK 7 Update 9 有什么问题。
I had the same problem when I recently installed JDK 7 Update 9. My eclipse did not open and when I run "java -version" from CMD, it did not work either.
I had PATH variable set to the correct bin directory.
Anyways, eventually when I set JAVA_HOME to the new installation directory, eclipse started fine. Not sure what is the problem with JDK 7 Update 9.
确保 Eclipse 首选项下“已安装的 JRE”下的所有设置均正确。
Make sure everything is setup correctly under "installed JREs" under the Eclipse preferences.
对我有用的简单解决方案，因为其他分辨率需要管理员权限，因此从命令提示符
eclipse -vm C:\Java\jdk1.7.0_72\bin\javaw
执行以下命令另外，要通过编辑快捷方式使 eclipse 快捷方式工作.在目标部分追加 -vm C:\Java\jdk1.7.0_72\bin\javaw
The simple solution that worked for me, since other resolution required admin privilege is executing the below command from command prompt
eclipse -vm C:\Java\jdk1.7.0_72\bin\javaw
Also, to make the eclipse shortcut work by editing the shortcut.Append -vm C:\Java\jdk1.7.0_72\bin\javaw in the target section
