First, prepare all the compiled packages to a folder
Like this

Next, create a new text document with the suffix. nuspec Fill in content

Start packing

nuget pack grpc-1.20.0-v141.nuspec

Now, a package called Google.Grpc.1.20.0.nupkg is generated under the schedule by directory

Next, install our package locally and test the availability of the package

nuget add Google.Grpc.1.20.0.nupkg -Source E:\nuget\packages

You can see that a new package ID related folder has been created under E:\nuget\packages, which contains the package we just packed

Next try installing

nuget install Google.Grpc -Source E:\nuget\packages

Note:% appdata%\NuGet\NuGet.Config(Windows) and ~ /. nuget/NuGet/NuGet.Config(Mac/Linux). Is the default nuget source configuration path

view folders

There is no shortage of one. The installation is successful
