我有一个简单的解决这个问题的方法。我通过将eclipse.ini文件中的vm路径更改为最新的jre路径来解决这个问题。

我点击了这个链接:https://youtu.be/lU_eb5Ki1kY

64位操作系统—> 64位Java、64位Eclipse 32位操作系统—> 32位Java、32位Eclipse

如果您在64位计算机中使用默认更新更新Java版本(并且您有32位浏览器)，Java将安装32位版本。您应该找到64位java版本并安装它。

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

编辑eclipse.ini文件以更新新更新的JDK。以前我有jdk1.7.0_09，现在更新到jdk1.7.0_80, eclipse抛出了这个错误。

要运行Eclipse，必须提供Java运行时环境(JRE)或Java开发工具包(JDK)。没有 找到Java虚拟机后，搜索如下 C:/Program Files/Java/jdk1.7.0_09/bin/javaw

更新eclipse.ini之后，

-vm
C:/Program Files/Java/jdk1.7.0_09/bin/javaw

to

-vm
C:/Program Files/Java/jdk1.7.0_80/bin/javaw

Eclipse工作正常。

在eclipse.ini文件中，需要更新VM的路径，使其指向机器上安装javaw.exe的同一位置。

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
    Path    REG_EXPAND_SZ    C:\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\

m Files (x86)\Perforce;C:\ProgramFiles\010 Editor;C:\Program Files\Microsoft SQL Server\130\Tools\Binn\;C:\ProgramFiles\
Git\cmd;C:\Program Files (x86)\Skype\Phone\

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%
C:\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Fi
les\Intel\DMIX;c:\Program Files (x86)\Microsoft SQL Server\90\Tools\binn\;C:\Program Files (x86)\Perforce;C:\ProgramFile
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 


<#
Add-Type @'

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

if (-not ("MyClass" -as [type])) {

p.s. there's no Remove-Type; see this answer for more on how to best work around this limitation:

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
} -ArgumentList $link,$OutputDir
