golang+dep+installation

Golang is an open source programming language that has gradually become popular in recent years and is adopted by more and more developers. Relying on the efficiency and simplicity of the Go language, many developers are using it to develop high-performance applications. In addition, in the Go language running environment, you can also use package management tools such as dep to complete dependency management tasks. Next, we will focus on the installation process of golang and dep.

1. Install Golang

Before introducing dep, let’s first understand the installation method of Golang. Below we will introduce the installation methods of Golang on three platforms: MAC, Linux and Window.

1. MacOS

MacOS users can download the latest version of Golang on the official website https://golang.org/dl/. Installation through source code is more complicated under MacOS, so we recommend MacOS users to directly download the binary file and install it.

After the download is completed, open the terminal and decompress the downloaded file, and then copy the decompressed folder to the /usr/local directory:

$ sudo tar -C /usr/local -xzf go1.14.1.darwin-amd64.tar.gz

Then edit the user's bash profile file, add the /usr/local/go/bin directory to the PATH environment variable to ensure that the go command can be run directly from any location:

$ export PATH=$PATH:/usr/local/go/bin

2. Linux

Linux users can also download the Golang installation package from the official website. The download address is https://golang.org/dl/. However, there is generally a software repository under Linux, and we can simply install it through tools such as apt-get or yum.

Taking the Ubuntu system as an example, users can install it through the following command:

$ sudo apt-get update
$ sudo apt-get install golang

3. Windows

Windows users can go to the Golang official website https:/ Download the installation package from /golang.org/dl/. After downloading the exe file, double-click to install it. When installing, you need to pay attention to setting environment variables to ensure that the go command can be run anywhere.

2. Install Dep

1. MacOS, Linux

Both macOS and Linux operating systems provide the third-party package management tool Homebrew, we can use it to install dep.

First, we need to install Homebrew, which can be installed through the command line:

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then install dep through Homebrew:

$ brew install dep

2. Windows

Dep can be installed through the Chocolatey package manager under Windows. We need to install Chocolatey first, open the command prompt as an administrator, and then execute the following command:

$ Set-ExecutionPolicy Bypass -Scope Process -Force
$ iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

Then, run the following command in the command prompt to install dep:

$ choco install dep

At this point, The installation process of Golang and dep has been fully introduced. However, it should be noted that when using dep to manage dependencies, we need to first enter the project root directory and create a file named Gopkg.toml there. Then, we can initialize this file through the dep init command and fill in the dependency information we need. After filling it out, use the dep ensure command to download the dependencies. By using Golang and dep, we can more conveniently manage dependencies and avoid version conflicts and installation problems.
