github - 为什么不能构建 godef.go？

Question

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

Answer 1

从多文件 Go 包或命令构建单个 Go 文件是没有意义的。构建所有文件。例如，

$ go build godef.go acme.go doc.go

或

$ go build *.go

或者，简单地构建包或命令

$ go build github.com/rogpeppe/godef

为什么要使用 go build 而不是 go install？

您为什么要“拉取源代码或 zip 文件”？使用 go get，它会为您执行 go install，例如，

$ go get -v -u github.com/rogpeppe/godef
github.com/rogpeppe/godef (download)
github.com/rogpeppe/godef/vendor/9fans.net/go/plan9
github.com/rogpeppe/godef/go/token
github.com/rogpeppe/godef/go/scanner
github.com/rogpeppe/godef/go/ast
github.com/rogpeppe/godef/vendor/9fans.net/go/plan9/client
github.com/rogpeppe/godef/vendor/9fans.net/go/acme
