cmd - 无效的语法。默认选项不允许超过“2”次

Question

我无法理解为什么会收到此错误：

ERROR: Invalid syntax. Default option is not allowed more than '2' time(s).
Type "SETX /?" for usage.

执行

C:\Users>setx JAVA_HOME "C:\DOC\JDK64\1.8.0.74"

SUCCESS: Specified value was saved.

C:\Users>setx PATH "%PATH%;%JAVA_HOME%\bin"
ERROR: Invalid syntax. Default option is not allowed more than '2' time(s).
Type "SETX /?" for usage.

C:\Users>setx PATH "%PATH%;%JAVA_HOME%bin"
ERROR: Invalid syntax. Default option is not allowed more than '2' time(s).
Type "SETX /?" for usage.

Answer 1

这很简单，但很隐蔽。运行 setx /? 我想答案就在那里。您作为参数（字符串）提供的 PATH 包含空格/空格。您应该将 PTH 括在“”之间。
