About "exports is not defined" error in Vue,webpack

Vue Project NPM Run dev Post error: Tip "Exports is not defined".

This problem is caused because of the Balbel configuration file. BABELRC problem:

{  "presets": [    ["env", {"modules": false}],    "Stage-2"  ],  "plugins": ["Transform-runtime"],  "Comments": false,  "env": {"    test": {      "presets": ["env", "stage-2"],      "plugins": ["Istanbul"]< c11/>}}}  

Remove {"Modules": false} where {"modules": false} prevents Babel from module conversion, see modules configuration for instructions, so modules to default settings, or delete the configuration.
