How to quickly and correctly configure the Vscode Golang development environment

Cover

Before starting

• This article is divided into two parts
• Installing Golang
• Configuring the Vscode Golang development environment
• Golang version 1.10.3
• Linux/macos The default installation path is/usr/local/go

Download & Install

• Download the corresponding version of Golang
• If it is MacOS can run brew install go to install

Environmental variable

The environment variable setting for this article is for Linux/macos, which is configured as follows:

$ vim ~/.profile#在文件末尾加入export GOROOT=/usr/local/goexport PATH=$PATH:GOROOT/bin

Goroot environment variable represents our go installation path, we can automatically find our go installation path when we use the IDE, to achieve the purpose of automatic configuration of the Go SDK.

/usr/local/go/bin This path is added to the environment variable path, we can directly enter the common commands such as go when using terminal.

After source ~/.profile the configuration is done to update the environment variables, enter go version Verify whether the configuration is successful

$ go versiongo version go1.10.3 darwin/amd64

Hello world!

Write your Hello world! Program
Inputvim hello.go

pakage mainimport "fmt"func main() {  fmt.println("Hello World!")}

Input go run hello.go to execute code, output:

Hello World!

Set up Vscode Go Extension

Open Vscode Search for go in the plugin bar

Go Extension

Since the wall is installed directly after the installation, you will be prompted that there are several plug-in installation failures

Failed

Workaround
Switch to%gopath%/using a terminal
Create a new missing folder according to the following directory structure

src├── github.com|      └── golang└── golang.org       └── x

We $ git clone git@github.com:golang/tools.git manually download the tools package by command, or download the extract directly, then put the Tools entire folder %GOPATH%/src/golang/x under the path, then we put the Lint folder under the Tools folder into the %GOPATH%/src/golang/x %GOPATH%/src/github.com/ following directory structure:

src├── github.com|      ├── golang|      |   └── lint|      ...└── golang.org       └── x           ├── tools           └── lint

Finally execute the go install github.com/golang/lint/golint command so that the lint installation succeeds (no return error)
Then we can continue to manually enter the command to install the failed plugin:

$ go install github.com/ramya-rao-a/go-outline$ go install github.com/acroca/go-symbols$ go install golang.org/x/tools/cmd/guru$ go install golang.org/x/tools/cmd/gorename...

Reopen Vscode If you are prompted to install the plugin, let it be installed automatically, and the result may return the following failure message:

Error message returned by terminal

For this scenario we continue to create the folder manually as above to download and install, taking the Gocode plugin as an example:

• Download the zip archive and unzip it to https://github.com/mdempsky/gocode according to the information
• Put the extracted files in%GOPATH%/src/github.com/mdempsky/gocode
• Performgo install github.com/mdempsky/gocode
