[Register-PSRepository在对象上找不到值引发错误

Posted 2021-03-28

在Windows Server上全新安装Powershell Core（通过Chocolatey）之后。我无法安装模块。

Install-Module PSSlack

返回错误

找不到与指定的搜索条件和模块名称匹配的对象

确定，让我尝试注册一个存储库

Register-PSRepository -Default

引发空异常

我在服务器上安装的Powershell ISE上收到相同的错误。我曾希望全新安装的Powershell内核能够神奇地修复。任何想法如何解决？

答案

在调用Invoke-Module之前在会话中运行此代码：

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
