vs-code中用liveServer打开vue-cli打包后的html，模拟查看线上路径问题

首先在扩展搜索liveServer下载安装

之后右键html就会出现liveServer命令

我用的vue-cli版本是3.2，为防止路径问题，在vue.config.js中修改publicPath为

module.exports = {
     
	publicPath: "./"
}	

完成重新打包
在vscode 配置 setting.json 中配置liveServer

 {
     
 	 "liveServer.settings.port": 8080, //设置本地服务的端口号
     "liveServer.settings.root": "./dist", //设置根目录，也就是打开的文件会在该目录下找,所以vue-cli打包后路径为dist就这样写
     "liveServer.settings.CustomBrowser": "chrome", //设置默认打开的浏览器
     "liveServer.settings.AdvanceCustomBrowserCmdLine": "chrome --incognito --remote-debugging-port=9222",
     "liveServer.settings.NoBrowser": false,
     "liveServer.settings.ignoredFiles": [//设置忽略的文件
         ".vscode/**",
         "**/*.scss",
         "**/*.sass"
     ]
}

配置完成后右键dist目录下的index.html，并用liveServer打开，这样就大功告成了
但是这样往往会出现目录路径问题，搞不清来龙去脉很难解决问题，这里推荐使用git bash实现模拟线上

• 首先全局安装npm install -g live-server
• 然后就可以直接使用了：
  • 打包好自己的项目
  • 使用 git bash 进入打包好的文件夹 dist
  • 直接使用命令 live-server 便可打开项目，这里打开后的项目即使打包的项目

附：live-server 参数说明：

--port=NUMBER - select port to use, default: PORT env var or 8080
--host=ADDRESS - select host address to bind to, default: IP env var or 0.0.0.0 ("any address")
--no-browser - suppress automatic web browser launching
--browser=BROWSER - specify browser to use instead of system default
--quiet | -q - suppress logging
--verbose | -V - more logging (logs all requests, shows all listening IPv4 interfaces, etc.)
--open=PATH - launch browser to PATH instead of server root
--watch=PATH - comma-separated string of paths to exclusively watch for changes (default: watch everything)
--ignore=PATH - comma-separated string of paths to ignore (anymatch-compatible definition)
--ignorePattern=RGXP - Regular expression of files to ignore (ie .*\.jade) (DEPRECATED in favor of --ignore)
--no-css-inject - reload page on CSS change, rather than injecting changed CSS
--middleware=PATH - path to .js file exporting a middleware function to add; can be a name without path nor extension to reference bundled middlewares in middleware folder
