Install go under Mac and configure the appropriate environment

This is a creation in Article, where the information may have evolved or changed.

A lot of tutorials, but not complete, so I encountered a variety of problems in the installation process. Later, a combination of several tutorials to configure. I used two methods, and later removed one of them. Here are my installation steps:

Method One: Homebrew

homebrewMac system is currently the most used management software tools, currently supported go, can be directly installed through the command go, for later convenience, it should be git mercurial installed:

1234	Brew Update && Brew upgradebrew install gitbrew install mercurialbrew install go

This will go allow you to see the relevant information after installation by using the command line input. Enter go env View environment information:

123456789101112131415

Goarch= "AMD64" gobin= "gochar=" 6 "goexe=" "gohostarch=" AMD64 "gohostos=" Darwin "goos=" Darwin "Gopath=" "gorace=" " goroot= "/usr/local/go" gotooldir= "/usr/local/go/pkg/tool/darwin_amd64" cc= "clang" gogccflags= "-fpic-m64-pthread- Fno-caret-diagnostics-qunused-arguments-fmessage-length=0-fno-common "cxx=" clang++ "CGO_ENABLED=" 1 "

Method Two: Pkg package installation

Go directly to the official download installation package, and then double-click Install, and then enter go , go env , and go version so on to see if it is installed.

Environment variable Configuration

1.0 See if Bash_profile exists

1	CD ~/.bash_profile

2.0 Create a Bash_profile Mac environment profile If it does not exist

1	Vim ~/.bash_profile

3.0 Adding GO Environment variables
If this is the first installation method, you only need to specify a second GOPATH . In order for your program to be compiled and executed directly from anywhere on the command line, add GOPATH the following bin :

12345678

#This is my personal bash_profile,when loaded at login.#===2015-08-15=== #GOPATHexport gopath= $HOME/documents/go_ Workspace#gopath binexport path= $PATH: $GOPATH/bin

However, after the second method is installed, the input go is displayed ommand not found: go , so it needs to be specified in the .bash_profile GOROOT following bin :

12345678910111213

#This is my personal bash_profile,when loaded at login.#===2015-08-15=== #GOROOTexport goroot=/usr/local/go# Gopathexport gopath= $HOME/documents/go_workspace#goroot binexport path= $PATH: $GOROOT/bin#gopath binexport PATH=$ PATH: $GOPATH/bin

After the general environment variable is changed, the restart takes effect. The file is automatically executed when the terminal is restarted .bash_profile .

If you want to take effect immediately, you can execute the following statement:

1	$ source. bash_profile

Problem:

If the open terminal does not take effect, append the above to the ~/.zshrc middle:

1	OPEN-E ~/.ZSHRC

Copy and paste save.
