简介

说明

本文用实例来介绍vue-cli4如何使用命令来创建项目。

系列文章

1. 创建工程

vue create demo_cli4

demo_cli4是文件夹名字也是项目名，若不存在会自动创建，若存在会安装到那个文件夹中。
项目名不允许含有大写字母
vue-cli2.x需要自己手动创建一个文件夹。

2.选择模板

选择：Manually select features

默认配置只有babel和eslint，其他的要自己再配置，所以选手动配置。

? Please pick a preset: (Use arrow keys)
> Default ([Vue 2] babel, eslint)
  Default (Vue 3) ([Vue 3] babel, eslint)
  Manually select features

3.选择组件

默认选项：

? Please pick a preset: Manually select features
? Check the features needed for your project: (Press <space> to select, <a> to toggle all, <i> to invert selection)
>(*) Choose Vue version
 (*) Babel
 ( ) TypeScript
 ( ) Progressive Web App (PWA) Support
 ( ) Router
 ( ) Vuex
 ( ) CSS Pre-processors
 (*) Linter / Formatter
 ( ) Unit Testing
 ( ) E2E Testing

选这几项即可：

 (*) Babel
 ( ) TypeScript
 ( ) Progressive Web App (PWA) Support
 (*) Router
 (*) Vuex
 ( ) CSS Pre-processors
>(*) Linter / Formatter
 ( ) Unit Testing
 ( ) E2E Testing

Linter / Formatter这个，若本处选中了，后边要关闭的话，有两种办法：

删除依赖及插件（本方法可运行起来，而且可以消除红色波浪线）
1. 删除package.json中的eslint依赖和插件（所有带有eslint字样的项）
2. 删除根目录下的.eslintrc.js文件
修改配置文件（本方法可运行起来，但无法消除红色波浪线）
1. 根目录下新建vue.config.js文件，添加如下内容：
  1. ```
  module.exports = {
      lintOnSave: false
  };
```

4.vue版本

上边用空格选完之后回车，会到下边界面。本处我选较为成熟的2.x

? Please pick a preset: Manually select features
? Check the features needed for your project: Choose Vue version, Babel, Router, Vuex, Linter
? Choose a version of Vue.js that you want to start the project with (Use arrow keys)
> 2.x
  3.x

5.是否使用history模式

（若选history：页面路由不使用 #）

建议选No，这样打包出来丢到服务器上可以直接使用了，后期要用的话，也可以自己再开起来。
选yes的话需要服务器那边再进行设置。

? Please pick a preset: Manually select features
? Check the features needed for your project: Choose Vue version, Babel, Router, Vuex, Linter
? Choose a version of Vue.js that you want to start the project with 2.x
? Use history mode for router? (Requires proper server setup for index fallback in production) (Y/n)

6. 语法检测级别

一般选择：ESLint + Standard config

? Please pick a preset: Manually select features
? Check the features needed for your project: Choose Vue version, Babel, Router, Vuex, Linter
? Choose a version of Vue.js that you want to start the project with 2.x
? Use history mode for router? (Requires proper server setup for index fallback in production) No
? Pick a linter / formatter config: (Use arrow keys)
> ESLint with error prevention only  //只检测错误
  ESLint + Airbnb config             //不严谨的检测
  ESLint + Standard config           //标准配置：自动纠正、自动格式化
  ESLint + Prettier                  //严格模式：使用Prettier进行风格统一

7.何时进行语法检测

一般选：Lint on save // 保存时检测。

等到commit的时候，问题可能都已经积累很多了

? Please pick a preset: Manually select features
? Check the features needed for your project: Choose Vue version, Babel, Router, Vuex, Linter
? Choose a version of Vue.js that you want to start the project with 2.x
? Use history mode for router? (Requires proper server setup for index fallback in production) No
? Pick a linter / formatter config: Standard
? Pick additional lint features: (Press <space> to select, <a> to toggle all, <i> to invert selection)
>(*) Lint on save   // 保存时检测
 ( ) Lint and fix on commit  // commit时检测和修复

8.babel,postcss,eslint等配置文件放置位置

一般选择：In dedicated config files //独立放置

这样可以让package.json干净些

? Please pick a preset: Manually select features
? Check the features needed for your project: Choose Vue version, Babel, Router, Vuex, Linter
? Choose a version of Vue.js that you want to start the project with 2.x
? Use history mode for router? (Requires proper server setup for index fallback in production) No
? Pick a linter / formatter config: Standard
? Pick additional lint features: Lint on save
? Where do you prefer placing config for Babel, ESLint, etc.? (Use arrow keys)
> In dedicated config files  // 独立文件放置
  In package.json            // 放package.json里

9.是否保存预设值

是否保存以便下次继续使用这套配置

如果选y，则会让你写一个配置的名字：Save preset as: name

? Please pick a preset: Manually select features
? Check the features needed for your project: Choose Vue version, Babel, Router, Vuex, Linter
? Choose a version of Vue.js that you want to start the project with 2.x
? Use history mode for router? (Requires proper server setup for index fallback in production) No
? Pick a linter / formatter config: Standard
? Pick additional lint features: Lint on save
? Where do you prefer placing config for Babel, ESLint, etc.? In dedicated config files
? Save this as a preset for future projects? (y/N)
