cmd - 通过cmd命令解压文件(7-zip)

Question

我尝试通过 CMD 解压缩文件。

所以我安装了 winzip(及其 cmd 插件)、winrar 和 7-zip。

但是当我尝试 execute a command通过 CMD:

7z e myzip.zip

它给出了下一个错误:

7z is not recognized as an internal or external command

另外，我将7-z的文件夹添加到环境变量中(属性-->高级-->环境变量-->用户变量-->选择路径，并添加C:\Program Files\7-Zip

可能是什么原因？

Answer 1

在命令提示符中执行以下操作对我来说很有效，添加到我的用户环境变量也很好:

set PATH=%PATH%;C:\Program Files\7-Zip\
echo %PATH%
7z

您应该看到输出(或类似的内容 - 因为这是在我运行 Windows 7 的笔记本电脑上):

C:\Users\Phillip>set PATH=%PATH%;C:\Program Files\7-Zip\

C:\Users\Phillip>echo %PATH%
