Next, we will introduce how to install Golang packages through the command line.

• Use go get command

go get is a very powerful command. It can not only obtain source code, but also automatically install dependencies. item. Before installing the package, you need to set the GOPATH environment variable. This variable represents the root directory of the Golang project. You can enter the following command in the terminal to set it up:

export GOPATH=$HOME/go

Next, run the following command to install the corresponding Golang package:

go get github.com/user/repo

Among them, github.com/user/repo represents the path of the package you want to install, which can be modified according to your needs. After the installation is complete, you can find this package in the $GOPATH/src/github.com/user/repo path.

go install github.com/user/repo

After the installation is completed, the corresponding binary file will be generated in the $GOPATH/bin path.

2. Install Golang source code

When developing Golang applications, it is necessary to use the complete Golang source code. The following are the steps on how to install the Golang source code:

• Download the source code

You can find the Golang source code on the official website, or use the following command to download it from the command line:

hg clone -u release https://go.googlesource.com/go

Among them, release represents the Golang version number you want to download. After the download is complete, you can find a folder named go in the current directory.

• Compile source code

After downloading the source code, you need to compile it. Use the following command to compile:

cd go/src
./all.bash

After executing the above command, compilation and testing will be automatically performed. This process may take some time, depending on your machine capabilities and environment.

• Configure environment variables

After the compilation is completed, you need to add the go/bin directory to the PATH environment variable, which allows you to Call Golang binaries directly from the command line.

export PATH=$PATH:/path/to/go/bin
