Question

我已经看到了很多关于此的查询。但是这些都无法解决我的问题。我正在尝试构建一个Cordova Android应用程序。但是Cordova要求总是失败，因为它找不到JAVA_HOME。我收到的错误在下面

C:\Android-Dev\WorkSpace\myTFS>cordova requirements

Android Studio project detected

Requirements check results for android:
**Java JDK: not installed

下面是我的JAVA主页和路径变量设置。我知道很多人都要求在PATH变量中提供bin文件夹的路径。但是它仍然无法正常工作。下面是我的系统变量

C:\Android-Dev\WorkSpace\myTFS>echo %JAVA_HOME%
C:\Program Files\Java\jdk1.8.0_171

C:\Android-Dev\WorkSpace\myTFS>echo %path%
C:\Program Files\Java\jdk1.8.0_171\bin;C:\Program Files\nodejs\;C:\Android-Dev\SDK\platform-tools;C:\Android-Dev\SDK\tools;C:\Program Files\Android\Android Studio\gradle\gradle-4.4\bin;C:\User
s\SAHAA2\AppData\Roaming\npm

这与访问问题有关吗？ 无法运行“ javac -version”，请确保您已安装JDK。

任何帮助将不胜感激。我会避免像很多人以前所提出的那样再次提出这个问题，但是似乎没有任何工作对我有用。因此，再次提出相同的问题。任何需要更多详细信息的人请告诉我

这可能是由于JAVA_HOME路径中的空间不足。将C:\Program Files\Java\jdk1. 8.0_171替换为C:\Progra~1\Java\jdk1. 8.0_171

科尔多瓦无法找到JAVA_HOME
