Where is the golang package?

Golang is an efficient, concise, safe, and concurrent programming language launched by Google. Its powerful library mechanism makes it very convenient to use packages in Golang, and the storage location of Golang packages is also easy to find.

1. Setting of GOPATH

When using Golang, you first need to set GOPATH. This variable points to the root directory where all Golang codes, libraries and binary files are stored. GOPATH can be set in the terminal environment or in the editor or IDE's settings. The method to set GOPATH in the terminal is as follows:

export GOPATH=/path/to/your/gopath

In Windows systems, you can right-click "Computer" -> "Properties" -> "Advanced System Settings" -> "Environment Variables" to set GOPATH.

2. Golang package storage location

After setting GOPATH, the Golang package storage location is in the src folder under GOPATH. The src folder is the folder where Golang source code is stored. By default, all Golang packages are also in it.

For example, if GOPATH is set to ~/go, then the ~/go/src folder is where all Golang packages are stored.

3. Reference to external packages

In addition to storing the codes and packages written by ourselves in GOPATH, we can also use packages written by others. In Golang, you can use the "go get" command to download and install third-party packages.

For example, use the following command to download and install the gin framework:

go get github.com/gin-gonic/gin

This way you can import this in your own project Packaged:

import "github.com/gin-gonic/gin"

It should be noted that when referencing external packages, the installed packages will be saved in the pkg folder under GOPATH , the generated executable file will be saved in the bin folder under GOPATH.

Conclusion

Through the above introduction, we can see that the storage location of the Golang package is very easy to find. At the same time, Golang's powerful library mechanism allows us to easily reference packages written by others to implement our own needs, greatly improving development efficiency.
