我正在尝试更新较旧的NPM / Node代码库，以使我在运行npm run build时可以正确编译，但是我遇到了一些问题，它吐出了大量与 scss 相关的问题
错误消息：You may need an additional loader to handle the result of these loaders
完整错误消息：
ERROR in ./src/containers/App/styles/app.scss
Module build failed (from ./node_modules/mini-css-extract-plugin/dist/loader.js):
ModuleParseError: Module parse failed: Unexpected character '@' (5:0)
File was processed with these loaders:

You may need an additional loader to handle the result of these loaders.

23 error If you do, this is most likely a problem with the redux-easy-boilerplate package,
23 error not with npm itself.

23 error webpack --progress --verbose --colors --display-error-details --config webpack/common.config.js
23 error You can get information on how to open an issue for this project with:
23 error npm bugs redux-easy-boilerplate
23 error Or if that isn't available, you can get their info via:
23 error npm owner ls redux-easy-boilerplate
23 error There is likely additional logging output above.
