“go build”不会在golang中生成文件

Question

我以前是用来go build生成文件的。但我只能 generate main，这意味着go build main.go工作而go build dao.go不会产生任何东西？我怎样才能生成dao？

Answer 1

来自go help build：

When the command line specifies a single main package,

build writes the resulting executable to output.

Otherwise build compiles the packages but discards the results,

serving only as a check that the packages can be built.
