After adding the require line and run "go mod tidy", the program compiles
successfully.
Thanks for your help!
But I still have some confusions.
1. Why does "go build" still connect to go101.org even if the wording
"go101.org" doesn't appear in any source code and go.mod files?
2. "Why doesn't "go build" run "go mod tidy" automatically?
3. Now, each "go build" run will stil connect to go101.org firstly, even of
the replace line is there.
Even if the connection fails, the build will still succeed. Then what
the meaningless to connect to
the old import paths which have been replaced.
