由于执行政策，面临小而繁忙的问题。

编写了一个 Powershell 脚本来使用“sharepointclientcomponents”下载 SharePoint 文件。

但是每次我们执行它时，都会抛出一个错误，说“未进行数字签名”。为此，每次都必须首先运行“Set -ExecutionPolicy RemoteSigned”。

有没有办法永久设置这个执行策略，以便我们可以安排代码？

您的想法将对我们有很大的帮助！

提前感谢一吨！！！！

这是我们尝试过的

请尝试将代码第一行中的“Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass”替换为“Set-ExecutionPolicy Bypass -Scope Process -Force”，它将帮助您永久设置此执行策略。

以下是修改后的代码：
