chrome调试时只能在打开的浏览器里进行调试，其它打开的chrome浏览器就不能调试了，怎么解决。

右键点击 Chrome 的快捷方式图标，选择属性 在目标一栏，最后加上--remote-debugging-port=9222 注意要用空格隔开

lanch.json 文件配置

{"version": "0.2.0","configurations": [{"name": "Attach to Chrome","port": 9222,"request": "attach","type": "chrome","url": "http://localhost:8056/add-system/","webRoot": "${workspaceFolder}","sourceMapPathOverrides": {"webpack:///src/*.vue": "${workspaceFolder}/src/*.vue","webpack:///./src/*.js": "${workspaceFolder}/src/*.js"},}]
}

打开浏览器，当前端页面进入 http://localhost:8056/add-system/ 后就会自动走入断点。如果多个浏览器都想走入调试可以设置多个配置，然后设置同时启动。

启动两个调试方法

{"version": "0.2.0","configurations": [{"name": "Attach","port": 9222,"request": "attach","type": "chrome","url": "http://localhost:8056/add-system/","webRoot": "${workspaceFolder}","sourceMapPathOverrides": {"webpack:///src/*.vue": "${workspaceFolder}/src/*.vue","webpack:///./src/*.js": "${workspaceFolder}/src/*.js"}},{"type": "chrome","request": "launch","name": "Chrome","url": "http://localhost:8056/add-system/","webRoot": "${workspaceFolder}","sourceMapPathOverrides": {"webpack:///src/*.vue": "${workspaceFolder}/src/*.vue","webpack:///./src/*.js": "${workspaceFolder}/src/*.js"}}],"compounds": [{"name": "启动所有","configurations": ["Chrome","Attach"],"stopAll": true}]
}
