当我遇到这样的问题时，在我的情况下，我用x86 Eclipse安装了x64 JDK + JRE。所以安装x86 JDK + JRE解决了我的问题:)我还在eclipse文件夹中创建了JRE文件夹，并将bin文件夹从我的本地路径C:\Program Files (x86)\Java\jre7复制到..\eclipse\ JRE \。

结果证明，我所需要做的就是将“路径”更改为:

“C: \ Windows \ system32系统;C: \ Windows; C: \ Windows \ system32系统\ Wbem; C:\Program Files (x86)\ Java; C:\Program Files (x86) \ Java \ jdk1.6.0_14 \ bin”

这样就成功了:)

不要依赖windows path变量，因为它几乎在每次更新中都会更改。例如，chrome(64位机器上的32位)java更新将全系统64位JVM替换为32位JVM。还要注意的是，这个条目必须是eclipse.ini中的最后一个条目，否则它将不起作用，并且-如前所述- eclipse.exe不会计算JAVA_HOME变量。

即使你的JAVA_HOME和路径配置有效，他们可能有这个问题，所以 最简单的方法是打开eclipse安装文件夹中的eclipse.ini

虚拟机 C:\Program Files\Java\ jdk1.7.0_71 \ bin \ javaw.exe

将C:\Program Files\Java\ jdk1.7.0_71\bin\javaw.exe替换为jdk或jre的路径

在eclipse文件夹中创建一个批处理文件，并在其中写入:

eclipse -vm C:\Sun\SDK\jdk\jre\bin\javaw.exe

看到 http://wiki.eclipse.org/FAQ_How_do_I_run_Eclipse%3F

别担心，我也被这个错误和致命的破坏，当我得到它，我是如此沮丧，甚至我是给离开一个android编程，但我得到了它，简单地首先复制这段代码，并粘贴在你的系统变量下路径…

C：\程序文件;C：\Winnt;C：\Winnt\System32;C：\程序 Files\Java\jre6\bin\javaw.exe

现在从你的路径复制“jre”文件夹，就像我在这个路径下有“jre”一样

            C:\Program Files\Java

并将其粘贴到eclipse文件夹中意味着放置eclipse.exe文件的位置。比如我在这个位置设置了日食

    F:\Softwares\LANGUAGES SOFTEARE\Android Setup\eclipse

所以在eclipse文件夹中粘贴jre文件夹。如果您有“jre6”，则将其重命名为“jre”....运行你的eclipse，你会得到解决方案…

   //<<<<<<<<<<<<<<----------------------------->>>>>>>>>>>>>>>>>>>                 

其他方案:2

如果上述步骤无法解决问题，请执行以下步骤

从您的Java路径(如C:\Program Files\Java\jre6*)复制文件夹“jre” 等，并将其粘贴到您的eclipse目录(Where is your eclipse 可用) 打开eclipse。ini文件。 像这样更改javaw.exe文件的目录

-vmF:\Softwares\LANGUAGES SOFTEARE\Android Setup\eclipse Indigo version 32 Bit\jre\bin/java .exe

现在，当你启动eclipse时，它将搜索javaw.exe，所以它将搜索eclipse.ini中的路径，因为它现在在同一个文件夹中，它将启动javaw.exe，它将开始工作。

我也遇到过这个问题。我的案例如下:

在文本:

HKEY_CURRENT_USER\Environment
    Path    REG_SZ    %JAVA_HOME%\bin;C:\ProgramFiles\nodejs

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
    JAVA_HOME    REG_SZ    C:\ProgramFiles\Java\jdk

C:\Users\ssfang> echo %^JAVA_HOME% = "%^JAVA_HOME%" = %%JAVA_HOME%% %JAVA_HOME%
%JAVA_HOME% = "%^JAVA_HOME%" = %C:\ProgramFiles\Java\jdk% C:\ProgramFiles\Java\jdk

我发现他们的注册表值Path的类型是不同的，所以我用下面的命令检查路径是否有效:

C:\Users\ssfang> where node java
C:\ProgramFiles\nodejs\node.exe
INFO: Could not find "java".

因此，我通过以下命令(Setx)重置本地(当前用户)环境:

C:\Users\ssfang> setx PATH %^JAVA_HOME%\bin;"C:\ProgramFiles\nodejs"

SUCCESS: Specified value was saved.

C:\Users\ssfang> reg query HKEY_CURRENT_USER\Environment /v Path

HKEY_CURRENT_USER\Environment
    Path    REG_EXPAND_SZ    %JAVA_HOME%\bin;C:\ProgramFiles\nodejs

C:\Users\ssfang> where node java
C:\ProgramFiles\nodejs\node.exe
INFO: Could not find "java".

C:\Users\ssfang>echo %PATH%

s\010 Editor;C:\Program Files\Microsoft SQL Server\130\Tools\Binn\;C:\ProgramFiles\Git\cmd;C:\Program Files (x86)\Skype\
Phone\;%JAVA_HOME%\bin;C:\ProgramFiles\nodejs

但是，在当前流程中，它不能将这些更改传播到其他正在运行的流程。

但是，如果直接在“注册表编辑器”中修改用户环境变量，

those modifications to the environment variables do not result in immediate change. For example, if you start another Command Prompt after making the changes, the environment variables will reflect the previous (not the current) values. The changes do not take effect until you log off and then log back on. To effect these changes without having to log off, broadcast a WM_SETTINGCHANGE message to all windows in the system, so that any interested applications (such as Windows Explorer, Program Manager, Task Manager, Control Panel, and so forth) can perform an update.

详细信息请参见如何将环境变量传播到系统

在这里，我给出了一个powershell脚本来完成它:

# powershell -ExecutionPolicy ByPass -File
# Standard, inline approach: (i.e. behaviour you'd get when using & in Linux)
# START /B CMD /C CALL "foo.bat" [args [...]]
# powershell -ExecutionPolicy ByPass -WindowStyle Hidden -File myScript.ps1

    {
        System.Console.WriteLine("Hello world");
    }
}
'@
$a = 1..4;
[string[]]$b = "a","b","c","d";
[CSharp]::Method($a, $b);

I think it will be wanted when debugging.
It is much simpler to close a tab in Console and open new one in PowerShell_ISE.exe or close PowerShell.exe.

Or

Start-Job -ScriptBlock {
    param([uri]$url,$OutputDir)
    # download and save pages
    Invoke-RestMethod $url | Out-File "$OutputDir\$($url.Segments[-1])" -Force
