typesafe安裝：未安裝或找到JDK，即使它們是

Question

我安裝了JDK（1.7.0.3和1.8.0）。 我已經C:\\Program Files\\Java\\jdk1.7.0_03\\bin添加了路徑C:\\Program Files\\Java\\jdk1.7.0_03\\bin或C:\\Program Files\\Java\\jdk1.8.0並且還添加了系統變量JAVA_HOME和C:\\Program Files\\Java\\jdk1.7.0_03或C:\\Program Files\\Java\\jdk1.8.0 。

我已經下載了類型安全激活器，並在我的C:\\驅動器中提取它。 然后當我嘗試通過activator.bat或來自CMD的命令activator ui運行它時，會顯示以下錯誤：

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MS Windows 7。

附加信息：

Answer 1

我在Windows上遇到了類似的問題......“C：\\ Program”未被識別為內部或外部命令

將Java安裝到沒有空格的路徑並使用它作為我的JAVA_HOME解決了我的問題。
