GOPATH Overview

In Go language, GOPATH is an environment variable used to set the working directory of Go language code. In fact, GOPATH is a directory list that can contain multiple paths where our own Go code and dependency packages pulled from remote repositories are stored. These dependency packages are automatically maintained and updated by Go's tool programs.

The advantage of setting GOPATH is that we can modify and debug the code in our own working directory, and at the same time, we can freely reference and use third parties of the Go language. Library.

Now, let’s learn how to set GOPATH.

The first step is to enter the following command in the command line tool:

export GOPATH=/go/path

Among them, /go/path can be replaced with what you want The actual directory to set.

Of course, if you want to set it to the default directory, you can use the following command:

export GOPATH=$HOME/go

The second step, download the dependencies

After setting the GOPATH, we can use go Get command to download the required dependency packages, for example:

go get github.com/gin-gonic/gin

This command will download the gin library and all its dependency packages from GitHub to the $GOPATH/src directory.

We can use the go env command to check whether the GOPATH setting is complete

go env | grep GOPATH

The system will output the value of the GOPATH variable.
