Hello, I recently installed PowerShell 7.0.1 using the package installer found in the Git repo ([https://github.com/PowerShell/PowerShell](https://github.com/PowerShell/PowerShell)). The install completed fine and with no errors but, I’m getting an error related to NuGet when I try to do things like installing a module. Here’s an example of what I’m referring to: ``` PS /Users/cartersheehan\> Install-Module-Name AWSLambdaPSCoreNuGet provider is required to continuePowerShellGet requires NuGet provider version '2.8.5.201' or newer to interact with NuGet-based repositories.

Please don’t post just to “bump” - it typically gets you the reverse of what you want. I’m not sure if the TLS setting is only applicable to windows or not, but you may try this. ``` [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 Install-Module PowerShellGet -RequiredVersion 2.2.4 -SkipPublisherCheck ``` > **[PowerShell Gallery TLS Support](https://devblogs.microsoft.com/powershell/powershell-gallery-tls-support/)** > > Summary To provide the best-in-class encryption to our customers, the PowerShell Gallery has deprecated Transport Layer Security (TLS) versions 1.0 and 1.1 as of April 2020.

Doug, My apologies. I tried your suggestion to adjust the tls security setting but I still get the same prompt to install NuGet before the install of PowerShellGet can even happen. During the NuGet install I get the same error messages. ---

Carter, I’ll see if it’s consistent on my Mac. Have you tried any other version? ---

Doug, I have not tested any other version right now, I went right for the LTS version available in the Git repo. I’ve swapped over to the Windows side of my Mac (bootcamp), so I’m able to get around this problem for now. I’ve installed the same version on the Windows side of my machine and did not run into the same issue. ---
