vue-cli4 webpack4 report errors

还没有人认领这个 Issue。

When I installed the plugin and referenced it in vue.config.js, before using the plugin, I started the project and encountered the following error message
```package.json
"javascript-obfuscator": "2.5.0",
"webpack-obfuscator": "2.6.0"
```

```vue.config.js
const WebpackObfuscator = require('webpack-obfuscator');
```

```npm run dev
WARNING Compiled with 1 warning 10:39:31

warning in ./node_modules/.store/source-map@0.1.43/node_modules/source-map/lib/source-map/source-map-generator.js

Critical dependency: require function is used in a way in which dependencies cannot be statically extracted
```

Can anyone help me? Thank you very much

从报告的 vue.config.js 配置以及 package.json 中 webpack-obfuscator 依赖的版本开始。运行 npm run dev，并检查来自 source-map/lib/source-map/source-map-generator.js 的警告。完成的标准是确定该警告由插件还是依赖导致，并记录或修复兼容的配置。
