Unable to compile C# code in Edge-js package npm

Question

I met a problem like this below when I try to run 'yarn start' on my server like this:

return edge.initializeClrFunc(options);
                ^

I think the problem comes from lib "Edge-js" - miss the compiler, then I have installed all the .Net from here: https://dotnet.microsoft.com/en-us/download/dotnet/6.0/runtime. But after all it still not working... My server language is Javascript,nodejs v16.15.0, and my dotnet version 6.0.202. I hope somebody can help me to resolve this problem cus it takes me 2 days for fixing it. Finally, thanks for reading until here!
