0. 问题： scoop 本身不支持安装包有解压密码的自动解压。

scoop 本身不支持安装包有解压密码的自动解压。因此在安装 MAS 时会卡在解压处，无法继续安装。

1. 7z 命令手册

7z 命令是支持的： 7z x FILENAME.7z -pPWD -oOUTDIR

2. 查 Scoop 源码的解压函数

找到 Scoop 源码里的 “~\scoop\apps\scoop\current\lib\decompress.ps1” 文件。
文件封装了 Expand-7zipArchive 函数命令， 但参数没有能将密码传入的方法。

3. 试 Scoop 的 pre_install

Scoop Wiki 里提到了 pre_install 等说法。

在 MAS.json 中加入：

1
"pre_install": "7z x $dir\\$fname -p1234 $('-o' + $dir)"，

尝试了很多次还是不起作用，Scoop的策略是遇到压缩包先执行解压、再做后续的事情。所以这一句不会被执行，安装程序依旧卡在解压处，无法继续安装。

github 也有类似问题：

Does this no longer work? I've tried multiple different things of trying to set it to install / pre_install and neither seem to actually work, looking at task manager it seems that it's not actually calling 7-zip at all with the password and instead just defaulting to trying to extract the file without the password at all.
does extract_dir or extract_to support password any? as looking at https://scoop-docs.vercel.app/docs/concepts/App-Manifests.html#a-simple-example doesn't seem to show an example with > password protect files at all.

Use Expand-7zipArchive and pass arguments, sorry the password has not been supported in manifest.

So I actually figured out the situation, whenever the url ends in either .zip/.rar or any other rared typed of extension, it'll always throw the default extraction method, no matter the pre_install or installer stuff.. solution is just to append random bit at end that isn’t .zip/.rar or other rar type of extensions and then it’ll extract the file correctly with the installer or pre_install bits.`

4. 解决办法

下载时将文件后缀改为不是压缩包的格式，将 url 后面加上 #dl.7z_ , 下载完成后缀名就变成了 .7z_。

Scoop 的安装程序就不会自动执行默认的解压程序 Expand-7zipArchive ； 这样 pre_install 命令就可以正常工作。

修改后的安装配置文件：

mas_x.json
