如何在Ubuntu 18.04 WSL中安装最新版本NuGet.exe CLI？

The default apt repository for Ubuntu 18.04 only ships with the outdated NuGet 2.8.x, but there are two straightforward ways to get the latest 5.x.x version:

Method 1: Install the .NET SDK (Recommended) #

NuGet 5.x+ is tightly integrated with the .NET SDK, so installing the SDK gives you access to the latest NuGet tooling along with other .NET utilities. Here's how:

1. Add Microsoft's software repository to your system:

   wget https://packages.microsoft.com/config/ubuntu/18.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
   sudo dpkg -i packages-microsoft-prod.deb
   rm packages-microsoft-prod.deb
   

2. Install the .NET SDK 5.0 (or a newer version like 6.0 if preferred):

   sudo apt-get update
   sudo apt-get install -y apt-transport-https
   sudo apt-get update
   sudo apt-get install -y dotnet-sdk-5.0
   

3. Verify the installation:
   Run dotnet nuget --version — you should see a 5.x.x version number pop up if everything worked.

4. Run your package install command:
   Use dotnet nuget install Test.Nuget.Version -OutputDirectory packages instead of the standalone nuget command. It works exactly the same way for your use case.

Method 2: Install the standalone NuGet CLI #

If you only need the NuGet tool and don't want the full .NET SDK, you can download the official NuGet CLI binary directly:

1. Grab the latest NuGet CLI executable:

   wget https://dist.nuget.org/win-x86-commandline/latest/nuget.exe
   

2. Run it using Mono (since it's a Windows executable):
   First install Mono if you don't have it:

   sudo apt install mono-complete
   

   Then execute your command with:

   mono nuget.exe install Test.Nuget.Version -OutputDirectory packages
   

3. (Optional) Make it easier to use:
   Move the executable to your system path so you can run it without typing mono every time:

   sudo mv nuget.exe /usr/local/bin/nuget
   

   Now you can just run nuget install Test.Nuget.Version -OutputDirectory packages directly.

Method 1 is the more stable and maintainable option, as it keeps your NuGet tooling in sync with the official .NET ecosystem.
