我看到了很多关于这个的查询。但这些都不能解决我的问题。我正在尝试构建一个CordovaAndroid应用程序。但是科尔多瓦的要求总是失败，因为它找不到JAVA_HOME。我得到的错误如下
C:Android-DevWorkSpacemyTFS>cordova requirements

Requirements check results for android:

下面是我的 JAVA 主页和路径变量设置。我知道很多人要求在 PATH 变量中提供 bin 文件夹的路径。但它仍然不起作用。下面是我的系统变量
C:Android-DevWorkSpacemyTFS>echo %JAVA_HOME%
C:Program FilesJavajdk1.8.0_171
C:Android-DevWorkSpacemyTFS>echo %path%
C:Program FilesJavajdk1.8.0_171bin;C:Program Filesnodejs;C:Android-DevSDKplatform-tools;C:Android-DevSDKtools;C:Program FilesAndroidAndroid Studiogradlegradle-4.4bin;C:User

这是否与访问问题有关，如其所说无法运行"javac 版本"，请确保您已安装 JDK。
任何帮助将不胜感激。我本来不会像许多人以前问过的那样再次提出这个问题，但似乎没有什么对我有用。因此再次提出同样的问题。任何需要更多详细信息的人请告诉我
这可能是因为路径JAVA_HOME空间。将C:Program FilesJavajdk1. 8.0_171替换为C:Progra~1Javajdk1. 8.0_171
