如何处理scoop安装时总是出现 “iex : 使用“1”个参数调用“DownloadString”时发生异常:“基础连接已经关闭: 连接被意外关闭。””
如题，如果你在安装scoop时总是遇上
iex : 使用“1”个参数调用“DownloadString”时发生异常:“基础连接已经关闭: 连接被意外关闭。”
总结起来是因为网络问题，导致DownloadString一直异常。
后来我看了一下源码，发现所有的DownloadString指向的是后缀为.ps1的文件的网址，于是就用下面的代码可以直接安装，当然还是要网络，挂个梯子效果更好。
新建两个*.ps1文件
新建两个txt文件，然后一个命名为install.ps1，一个命名为core.ps1，然后将install.ps1中的!!!更换为core.ps1的文件位置（带文件名）
- install.ps1
# install.ps1
