typesafe安装: JDK没有安装或找到，即使它们是

Question

我安装了JDK ( 1.7.0.3和1.8.0)。我交替地添加了路径C:\Program Files\Java\jdk1.7.0_03\bin或C:\Program Files\Java\jdk1.8.0，并分别用C:\Program Files\Java\jdk1.7.0_03或C:\Program Files\Java\jdk1.8.0添加了系统变量JAVA_HOME。

我用play下载了typesafe激活器，并在我的C:\驱动器中提取它。然后，当我试图通过activator.bat或命令activator ui从CMD运行它时，会显示以下错误：

C:\activator-1.0.13>activator ui
'"C:\Program Files\Java\jdk1.8.0\bin\java.exe" -version 2>&1' is not recognized
as an internal or external command,
operable program or batch file.
'"C:\Program Files\Java\jdk1.8.0\bin\javac.exe" -version 2>&1' is not recognized
 as an internal or external command,
operable program or batch file.

A Java JDK is not installed or can't be found.
JAVA_HOME = "C:\Program Files\Java\jdk1.8.0"

Please go to
  http://www.oracle.com/technetwork/java/javase/downloads/index.html
and download a valid Java JDK and install before running Activator.

If you think this message is in error, please check
your environment variables to see if "java.exe" and "javac.exe" are
available via JAVA_HOME or PATH.

我正在使用微软的Windows 7。

Answer 1

我在Windows上也有类似的问题..。'C:\Program‘不被识别为内部或外部命令

将Java安装到没有空格的路径上，并使用它，因为我的JAVA_HOME为我解决了这个问题。

Answer 2

这对我有用: 1.以管理员身份打开命令提示符3。使用activator.bat 4导航到文件夹。键入‘激活者ui’而不是‘5。按回车。
