Installation

Default installation, the/usr/local/go directory is installed automatically

And the environment variables are set automatically.

Go env to view the current environment variables for Go

This go is going to do it.

GOPATHEnvironment variables

GOPATHEnvironment variables Specify the location of your workspace. It may be the only environment variable you need to set up when you develop the GO code.

According to the Convention, 3 directories need to be established under Gopath:

Bin stores the compiled executable file

Pkg to store package files generated after compilation

SRC Store the source code of the project

See gopath= through Go env /users/li/go is the go directory on the user's home

now I'm building Gopath in/data/web/gowork . Note that it must never be the same as your go install directory

cd/data/web/

Midir gowork

Add the Bin directory of the Gopath to the environment variable

Echo $PATH

VI ~/.bash_profile

Add two lines:

Export gopath= "/data/web/gowork"

Export path= "/data/web/gowork/bin: $PATH"

If you want to take effect immediately after confirming that there is no problem, you can execute the following command

SOURCE ~/.bash_profile

Review the following PATH environment variables again

Echo $PATH

Tip, before modifying the path variable, echo $PATH once, in case you mistake or lost the value of the $path variable can be used to re-apply the printed value.

First Program

　　

CD $GOPATH/SRC

mkdir Hellomygo

vim hellomygo/hellomygo.go

　　

" FMT " Func Main () {        fmt. Printf ("Hello, my go\n")}

Go Install Hellomygo

LS $GOPATH/bin

The resulting Hellomygo executable file is displayed

Can be entered in any other directory Hellomygo will be displayed

"Hello, My Go"

Direct input running command go run hellomygo/hellomygo.go also display

  "Hello, My Go"
