It looks like you are having network troubles.

The error that you are getting is:
"Received an unexpected EOF or 0 bytes from the transport stream." ("从传输流收到意外的 EOF 或 0 个字节。")

The particular file that it was trying to download was "grpc_csharp_ext.x64.dll". There is nothing particularly special about that file, so it sounds like you are getting random errors that prevent you from being able to download all of the necessary files. I imagine that the other errors that you have gotten involved other files.

You might have better success with the "Unplugged" installer.

You can find instructions and link for that here:
