英文:
why can not build godef.go?
问题
首先，我拉取源代码或压缩文件时，无论是哪种方式，当我执行go build godef.go时，都会显示相同的错误日志，如下所示：
# command-line-arguments
.\godef.go:55: undefined: acmeFile
.\godef.go:59: undefined: acmeCurrentFile
英文:
>first I pull the soure code or zipfile, They both show the same error log like this when I go build godef.go.
go build godef.go
# command-line-arguments
.\godef.go:55: undefined: acmeFile
.\godef.go:59: undefined: acmeCurrentFile

从多个Go文件构建单个Go文件包或命令是没有意义的。请构建所有文件。例如，
$ go build godef.go acme.go doc.go
或者
$ go build *.go
或者，简单地构建包或命令
$ go build github.com/rogpeppe/godef
为什么你使用go build而不是go install？
为什么你要“拉取源代码或压缩文件”？使用go get，它会为你执行go install，例如，
$ go get -v -u github.com/rogpeppe/godef

参考：
英文:
Building a single Go file from a multi-file Go package or command makes no sense. Build all the files. For example,
$ go build godef.go acme.go doc.go
or
$ go build *.go
Or, simply build the package or command
$ go build github.com/rogpeppe/godef
Why are you using go build instead of go install?
Why did you "pull the soure [sic] code or zipfile"? Use go get, which does a go install for you, for example,
$ go get -v -u github.com/rogpeppe/godef
