4.5.0降級到3.3.12
1.D:\CodePractice\2021\00_BoilerPlate>npm uninstall webpack-cli
2.D:\CodePractice\2021\00_BoilerPlate>npm install webpack-cli@^3.3.12
四、重新啟動
D:\CodePractice\2021\00_BoilerPlate>npm start
> 00_boilerplate@1.0.0 start D:\CodePractice\2021\00_BoilerPlate
> webpack-dev-server? --mode development --inline --hot --open

WARNING (@babel/preset-env): We noticed you're using the `useBuiltIns` option without declaring a core-js version. Currently, we assume version 2.x when no version is passed. Since this default version will likely change in future versions of Babel, we recommend explicitly setting the core-js version you are using via the `corejs` option.
You should also be sure that the version you pass to the `corejs` option matches the version specified in your `package.json`'s `dependencies` section. If it doesn't, you need to run one of the following commands:
? npm install --save core-js@2? ? npm install --save core-js@3
? yarn add core-js@2? ? ? ? ? ? ? yarn add core-js@3
