In recent years, Golang has become more and more popular among developers. Due to its characteristics such as parallelism, easy deployment, and high efficiency, it is widely used in various scenarios. When developing with Golang, installing dependencies is a necessary step.
This article will share from the following aspects:
Before you start, you need to confirm that you have installed the Golang development environment. If you haven't installed it yet, you can go to the official website to download the latest version.
There are two main ways to install dependencies in Golang:
In the terminal or command line window, use the go get command to download and install the specified packages.
For example:
go get github.com/gin-gonic/gin
This command will download the source code of the gin framework and install it into the $GOPATH directory.
The steps are as follows:
For example, we will manually install a dependency package below:
// 下载源码并解压 wget https://github.com/globalsign/mgo/archive/v2.0.tar.gz tar -zxf v2.0.tar.gz // 将源码复制到 $GOPATH/src 目录下 cp -r mgo-2.0 $GOPATH/src/github.com/globalsign/mgo // 安装依赖包 cd $GOPATH/src/github.com/globalsign/mgo go install
Although using go get or manually installing dependency packages can meet the needs of installing dependencies, this method has a disadvantage: the version numbers of these dependency packages are not managed. If the dependency packages are Without updates, we cannot determine whether we need to update the version of dependent packages, and cannot effectively manage the versions and upgrades of dependent packages.
Therefore, many Golang dependency management tools have appeared in the industry, such as Dep, Glide, Go Modules, etc. This article will not introduce it further, you can choose according to your own needs.
The above are only some commonly used Golang libraries and dependencies, which are not enough to cover all scenarios. During development, you can select and integrate based on your needs.
This article introduces the methods and steps for Golang to install dependencies, as well as commonly used Golang libraries and dependencies. I hope this article can help you install dependencies during Golang development.
