如何在Powershell和7zip中正确设置路径？ [英] How to properly set path in Powershell and 7zip?

问题描述

我有一个Powershell脚本，可以通过7zip创建自解压存档。但它收到此错误：

I have a Powershell script to create a self-extracting archive via 7zip. But it's receiving this error:

找不到指定的SFX模块

cannot find specified SFX module

Powershell代码为：

The Powershell code is:

set-alias sz "$env:ProgramFiles\7-Zip\7z.exe
sz a -t7z -sfx -ppassword $fullpath $filetostore

两者变量有效。我试过 -sfx 和 -sfx7z.sfx ，同样的错误。7z.sfx文件确实位于使用7zip的正确文件夹中。我还可以验证别名是否正常运行，因为在运行代码时会出现7zip版权（因此正在启动7zip命令行）。此命令在Powershell外部有效。

Both variables are valid. I've tried -sfx and -sfx7z.sfx, same error. The 7z.sfx file is indeed in the correct folder with 7zip. I can also verify the alias is working, as the 7zip copyright appears when running the code (so 7zip commandline is being initiated). This command works outside Powershell.

我也尝试过 Set-Location 到7zip文件夹中，但还是出现同样的错误。我想念什么？

I'm also tried Set-Location into the 7zip folder, but same error. What am I missing?

推荐答案

似乎您应该将7-zip文件夹添加到 PATH 环境变量中，以使事情变得容易：

It seems you should add the 7-zip folder to your PATH environment variable to make things easier :

#find the 7-zip folder path
$7zPath = (Get-ChildItem "C:\Program Files","C:\Program Files (x86)" -Include "7-zip" -Recurse -ErrorAction SilentlyContinue).FullName

#add it to PATH environment variable
$env:Path += ";$7zPath;"

然后您可以运行 7z -sfx ，关于 SFX 模块没有错误。

Then you can run 7z -sfx with no errors about the SFX module.
