Proxy Issues with Install Module
A per Keith Hill's suggestion, adding the PowerShellGallery repo manually worked:
Register-PSRepository -Name PSGallery -SourceLocation https://www.powershellgallery.com/api/v2I had trouble getting this working with the -proxy switch, so I set the proxy via netsh which did the trick:
netsh winhttp set proxy proxy-server="http=myproxy:8080"
Proxy can be set via -Proxy parameter of many network cmdlets or $PSDefaultParameterValues = @{ "*:Proxy"="http://proxy:port" }
