vue2企业级项目（一）

创建项目，并创建项目编译规范

1、node 版本

由于是vue2项目，所以 node 版本比较低。使用 12.18.3 左右即可

2、安装vue

安装指定版本的vue2

npm i -g vue@2.7.10
npm i -g @vue/cli@4.4.6

3、编辑器规范

1. vscode安装 EditorConfig for VS Code插件

2. 项目根目录创建 .editorconfig文件

3. 填写一下示例内容

   # 表示是最顶层的配置文件，发现值为true时，才会停止查找.editorconfig文件
   root = true# 表示配置所有的文件
   [*]
   # utf-8格式
   charset = utf-8
   # 缩进为2个空格
   indent_style = space
   indent_size = 2
   # 结尾都是用crlf格式, 并且文件保存是结尾换行
   end_of_lint = crlf
   insert_final_newline = true
   # 移除无效空格
   trim_trailing_whitespace = true# 表示配置所有的md文件
   [*.md]
   insert_final_newline = true
   trim_trailing_whitespace = true
