First, install the Golang SDK
Method One: Download the installation package SDK
installation package Download Address: https://golang.org/dl/
Download the two in the diagram
1. Double-click the. tar file, it will be automatically extracted into a folder named "Go", dragged to your user name, remember the path;
My path is:/users/haodaibao/go
2, double-click the PKG package, follow the guidelines, you can install the success.
3. Verify that the SDK installation is successful
Enter go version at the command line and get to version of Go, which means the installation was successful. The results of my verification are as follows:
Go version go1.10.3 darwin/amd64
Second, configure environment variables
1, open the terminal input CD ~ Enter the user home directory;
2. Enter the Ls-all command to see if there is a. bash_profile;
3, the existence of both using VIM. Bash_profile Open file;
4 input I into VIM editing mode;
5, enter the following code,
which
-Gopath: The root directory for daily development.
-GOBIN: Is the bin directory under Gopath.
Use method one installation, configurable
Gopath=/users/haodaibao/go
exportgobin= $GOPATH/binexport
Path= $PATH: $GOBIN
6. Click ESC and enter: Wq Save and exit the edit. You can enter Vim. Bash_profile to see if the save was successful.
7, the input source ~/.bash_profile completes the configuration to the Golang environment variable, the configuration succeeds does not have the prompt.
8. Enter go env to view the configuration results, my results are as follows:
➜~ Go env
Goarch= "AMD64"
Gobin= ""
Gocache= "/users/haodaibao/library/caches/go-build"
Goexe= ""
Gohostarch= "AMD64"
Gohostos= "Darwin"
Goos= "Darwin"
Gopath= "/users/haodaibao/go"
Gorace= ""
goroot= "/usr/local/cellar/go/1.10.3/libexec"
Gotmpdir= ""
Gotooldir= "/usr/local/cellar/go/1.10.3/libexec/pkg/tool/darwin_amd64"
gccgo= "Gccgo"
Cc= "Clang"
cxx= "clang++"
cgo_enabled= "1"
Cgo_cflags= "-g-o2"
Cgo_cppflags= ""
Cgo_cxxflags= "-g-o2"
Cgo_fflags= "-g-o2"
Cgo_ldflags= "-g-o2"
Pkg_config= "Pkg-config"
Gogccflags= "-fpic-m64-pthread-fno-caret-diagnostics-qunused-arguments-fmessage-length=0-fdebug-prefix-map=/var /folders/bp/sfrhrzls4q14mg9_wfj6q6j40000gn/t/go-build046962637=/tmp/go-build-gno-record-gcc-switches- Fno-common "
➜
Third, use command line debugging
1, create the project in the SRC directory of Go, such as my go directory for/users/haodaibao/go, I create folder MSTest path for/users/haodaibao/go/src/testgo;
2, create the file Main.go, enter the following code, and save.
Package Main
Import (
"FMT"
)
Func Main () {
Fmt. Println ("Hello");
}
3. Enter go build test.go on the command line to generate the exec file;
4, click this exec file, will pop up the command line to display the following running results:
Installation is successful!
