在配置前需要下载用到的包：
在下载包之前需要设置好环境变量：
# Golang export GOROOT=$HOME/go export GOPATH=$HOME/development/go export PATH=$PATH:$GOROOT/bin export PATH=$PATH:$GOPATH/bin
如果网络良好的话使用这种方法：
godoc：
go get golang.org/x/tools/cmd/godoc
这样会将godoc二进制文件安装到$GOROOT/bin目录里。
godef：
go get github.com/rogpeppe/godef
这样会将godef二进制文件安装到$GOPATH/bin目录里。
gocode 自动完成：
go get -u github.com/nsf/gocode
这样会将gocode二进制文件安装到$GOPATH/bin目录里。
go oracle
go get golang.org/x/tools/cmd/oracle
oracle二进制文件将出现在$GOPATH/bin目录里，将它移动到$GOROOT/bin目录里。
下面是emacs的golang配置：
;;; init-go --- golang ;;; Commentary: ;; http://tleyden.github.io/blog/2014/05/22/configure-emacs-as-a-go-editor-from-scratch/ ;; https://robinxiong.gitbooks.io/golang/content/section1/emacs.html ;; http://studygolang.com/topics/583 ;;; Code: (require-package ‘go-mode) (require-package ‘company-go) (require ‘go-mode) ;; removes all unused imports (add-hook ‘go-mode-hook ‘(lambda() (local-set-key (kbd "C-c C-r")‘go-remove-unused-imports))) ;; format the current buffer (add-hook ‘go-mode-hook ‘(lambda () (local-set-key (kbd "C-c C-f") ‘gofmt))) ;; format the buffer when save (add-hook ‘before-save-hook ‘gofmt-before-save) ;; show the go documentation for a given package ;; Note: godoc depends on the godoc utility. ;; It must be installed and on your $PATH. ;; To install it run: go get code.google.com/p/go.tools/cmd/godoc.

另一种方法：
注意：从github克隆的golang.org应该放在src目录里！
~/development/go/src ? git clone https://github.com/golang/tools golang.org/x/tools 正克隆到 ‘golang.org/x/tools‘... remote: Counting objects: 15398, done. 接收对象中: 8% (1232/15398), 404.01 KiB | 69.00 KiB/s
编译godoc：
go build golang.org/x/tools/cmd/godoc
注意：编译出的godoc二进制文件应该放在 ~/development/go/bin目录里!
安装golang教程（这个是英文版的）：
git clone https://github.com/golang/tour
go build golang.org/x/tour/gotour golang.org/x/tools/playground/socket/socket.go:37:2: cannot find package "golang.org/x/net/websocket" in any of: /home/z/go/src/golang.org/x/net/websocket (from $GOROOT) /home/z/development/go/src/golang.org/x/net/websocket (from $GOPATH)
怎么办？
? git clone https://github.com/golang/net
注意：gotour和net这2个目录和tools目录是平级的，它们都在$GOPATH/src/golang.org/x 目录下。
x
├── net
├── tools
└── tour
? go build golang.org/x/tour/gotour
安装中文版的教程：
git clone https://github.com/Go-zh/tour github.com/Go-zh/tour git clone https://github.com/Go-zh/tools github.com/Go-zh/tools
注意tour和tools是同级目录。
github.com/Go-zh
├── tools
└── tour
编译中文版教程：
go build github.com/Go-zh/tour/gotour
这时会在$GOPATH/src目录中出现一个gotour二进制文件，把它剪切到$GOPATH/bin目录中并重命名为gotour-zh。
在$GOPATH/bin中执行：./gotour-zh 即可开启浏览器。
安装godef：
git clone https://github.com/rogpeppe/godef github.com/rogpeppe/godef
go build github.com/rogpeppe/godef
github.com/rogpeppe/godef/acme.go:11:2: cannot find package "9fans.net/go/acme" in any of:
/home/z/go/src/9fans.net/go/acme (from $GOROOT)
/home/z/development/go/src/9fans.net/go/acme (from $GOPATH)
解决方法：
git clone https://github.com/9fans/go 9fans.net/go
然后再编译安装godef：
go build github.com/rogpeppe/godef
