Android Studio - JAVA_HOME 未指向有效的 JVM 安装

Android Studio - JAVA_HOME doesn't point to a valid JVM installation

提问by oneshotfinch

Having trouble firing up android studio. Get the following message: The environment variable JAVA_HOME (with the value of ?C:\Program Files\Java\jdk1.8.0_31) does not point to a valid JVM installation. The problem is that as far as I can tell, the environment variable I set up IS pointing to a valid install.

无法启动 android studio。获取以下消息：环境变量 JAVA_HOME（值为 ?C:\Program Files\Java\jdk1.8.0_31）未指向有效的 JVM 安装。问题是，据我所知，我设置的环境变量指向有效安装。

I've tried everything from renaming it to JDK_HOME, to pointing it to all the sub directories in the jdk folder, to uninstalling and reinstalling java and android studio about 3 time. I have triple checked that I have 64 bit JAVA installed (and that my computer is 64 bit). Pretty much at the end of my rope here. Help would be appreciated big time.

我已经尝试了一切，从将它重命名为 JDK_HOME，到将它指向 jdk 文件夹中的所有子目录，再到卸载和重新安装 java 和 android studio 大约 3 次。我已经三重检查我是否安装了 64 位 JAVA（并且我的计算机是 64 位）。几乎在我绳子的尽头。帮助将不胜感激。

Remember that you have to set the JAVA_HOME variable to C:\Program Files\Java\jdk1.8.0_31, just like you set the variable JDK_HOME. :)

请记住，您必须将 JAVA_HOME 变量设置为 C:\Program Files\Java\jdk1.8.0_31，就像设置变量 JDK_HOME 一样。:)

See this post for reference: Android Studio installation on Windows 7 fails, no JDK found

请参阅此帖子以供参考： Windows 7 上的 Android Studio 安装失败，未找到 JDK

Also, you could try installing an older version of java, as the newest ones might not be compatible with your IDE. Reference: Android Studio error: "Environment variable does not point to a valid JVM installation"

此外，您可以尝试安装旧版本的 java，因为最新版本可能与您的 IDE 不兼容。参考：Android Studio 错误：“环境变量未指向有效的 JVM 安装”

Delete your all user variable paths from Environments Variable, and keep only two (TEMP & TMP) variables, it will work.

从环境变量中删除所有用户变量路径，只保留两个（TEMP 和 TMP）变量，它会起作用。

To fix it, just remove "\bin" from my JAVA_HOME variable.

要修复它，只需从我的 JAVA_HOME 变量中删除“\bin”。

NOTE:be sure to put the JAVA_HOMEpath variable in the System variablesrather than the user variables. If the path variable is in User the Android Studio will not find the path.

注意：确保将JAVA_HOME路径变量放在.System variables而不是user variables. 如果路径变量在 User 中，Android Studio 将找不到路径。

You can try this Android Studio error: "Environment variable does not point to a valid JVM instalation"

你可以试试这个 Android Studio 错误：“环境变量没有指向有效的 JVM 安装”

this works for me. If you start 64bit Android Studio, you have to add JAVA_HOME as

这对我有用。如果您启动 64 位 Android Studio，则必须将 JAVA_HOME 添加为

"C:\Program Files\Java\jdk..."

If 32bit

如果是 32 位

"C:\Program Files(x86)\Java\jdk..."

and dont put "\bin" end of the path.

并且不要将 "\bin" 放在路径的末尾。

Ensure JAVA_HOMEis in the "System Variables" and points to the JDK short path. For example if the JDK is C:\Program Files\Java\jdk1.7.0_79set JAVA_HOMEto C:\PROGRA~1\Java\JDK17~1.0_7. I was getting the above error message initially upon install but it started working when I made this change, and it was not necessary to reboot.

确保JAVA_HOME在“系统变量”中并指向 JDK 短路径。例如，如果 JDKC:\Program Files\Java\jdk1.7.0_79设置JAVA_HOME为C:\PROGRA~1\Java\JDK17~1.0_7. 我最初在安装时收到上述错误消息，但是当我进行此更改时它开始工作，并且没有必要重新启动。

好几个星期都面临同样的问题。对我有用的是：从笔记本电脑上卸载所有 java，然后安装 jdk 7 64 位，删除 JAVA_HOME 并添加 JDK_HOME。

make JAVA_HOMEa system variable under environment variables and set it to C:\Program Files\Java\jdk1.8.0_31.

JAVA_HOME在环境变量下创建一个系统变量并将其设置为C:\Program Files\Java\jdk1.8.0_31.

After that logout and login back. This should eliminate the error message that you are getting. Then launch the Android Studio.

之后注销并重新登录。这应该消除您收到的错误消息。然后启动 Android Studio。
