在您的rules对象中，.eslintrc将"import/extensions"设置为never或0。

您应该检查是否已安装eslint-plugin-import，Airbnb样式指南配置使用它来处理进口和导出的覆盖。如果没有它，它会导致错误Unable to resolve path to module '_module-name_'和/或Missing file extension for "_module-name_" (import/extensions)。

同样，由于您将其安装在DEV依赖性中，因此您可以在全球范围内运行诸如./node_modules/.bin/eslint .或设置ESLINT之类的东西以运行eslint .
