通过cmd命令解压缩文件(7-zip)

Question

我尝试通过CMD解压缩文件.

所以我安装了winzip(及其插件到cmd),winrar和7-zip.

但是当我尝试通过CMD 执行命令时:

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,我在环境变量中添加了7-z的文件夹(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

在命令提示符下执行以下操作对我来说,也添加到我的用户环境变量工作正常:

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

您应该看到输出(或类似的东西 - 因为这是在我的笔记本电脑上运行Windows 7):

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

C:\Users\Phillip>echo %PATH%

关于Phil Street的职位：

如果运行的是64位操作系统，则它实际上可能安装在32位程序文件夹中，而不是默认的x64中。检查7-zip安装位置，如果安装在其中，Program Files (x86)则尝试使用以下方法：

PATH=%PATH%;C:\Program Files (x86)\7-Zip
