【我的学习】: Vue项目环境搭建
最近入坑vue. ，发现不知如何运行GitHub上的开源项目，很尴尬。经过查阅资料，成功搭建好项目环境，所以将环境搭建过程分享给你们。
1、相关环境
- VSCode(开发环境)
- node.js环境（npm包管理器）
- vue-cli 脚手架构建工具
- cnpm npm的淘宝镜像（因为有些npm有些资源被屏蔽或者是国外资源的缘由，常常会致使用npm安装依赖包的时候失败，全部可能须要npm的国内镜像---cnpm）我没装
2、环境安装
- 安装VSCode：https://code.visualstudio.com/下载并安装VSCode，安装过程很简单，一路“下一步”就能够了（傻瓜式安装）汉化步骤：EXTENSIONS搜索Chinese (Simplified) Language Pack for Visual Studio Code并安装 ---> shift+ctrl+p 搜索Configure Display Language并点击选择zh-cn
- 安装Node.js ： https://nodejs.org/en/下载并安装node，安装过程很简单，一路“下一步”就能够了（傻瓜式安装），安装完成以后输入node -v查看版本，node自带npm能够经过npm -v 查看，以下，说明安装成功：
3.安装vue-cli脚手架构建工具 ： css
在命令行中运行命令 npm install -g vue-cli ，而后等待安装完成。(注意，这里建议使用cnpm来替代npm，否则速度超级慢，会致使卡在那)，我没卡vue
4.新建vue项目（依赖包会自动安装）：打开vscode，ctrl+` 打开终端，切到要新建项目的目录，cd d:\vs2019Project\Study.Vue\study.vuejs 以后运行vue init webpack study.vuejs（这个命令的意思是初始化一个项目，其中webpack是构建工具，也就是整个项目是基于webpack的。其中study.vuejs是整个项目文件夹的名称，这个文件夹会自动生成在你指定的目录中），运行初始化命令的时候会让用户输入几个基本的选项，如项目名称，描述，做者等信息，若是不想填直接回车默认就好。node
D:\vs2019Project\Study.Vue>vue init webpack study.vuejs

5.项目配置：打开launch.json，配置以下：webpack
{
// 使用 IntelliSense 了解相关属性。
// 悬停以查看现有属性的描述。
// 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"type": "firefox",
"request": "launch",
"name": "vuejs: firefox",
"url": "http://localhost:8080",
"webRoot": "${workspaceFolder}/src",
"breakOnLoad": true,
"sourceMapPathOverrides": {
"webpack:///src/*": "${webRoot}/*"
}
}
]
}
6.运行项目：，运行命令 npm run dev（其中的“run”对应的是package.json文件中，scripts字段中的dev，也就是 node build/dev-server.js命令的一个快捷方式）项目运行成功后，浏览器会自动打开localhost:8080（若是浏览器没有自动打开，能够手动输入）。运行成功！git
