意外的标记 '{'。导入调用只需要一个参数

Question

“我对这一切都很陌生，这是我第一个发布的问题！我正在开发 react-native Android 应用程序。构建应用程序后，它向我显示一个错误 - 在 react-native 中出现意外令牌'{' , import call 只需要一个参数。 我已经检查了很多次我的源代码，但我没有任何与此错误相关的解决方案。我该怎么办？？

这是我的 pakage.json 文件-

虽然您没有提供任何明确的代码或环境信息来帮助我们了解导致此问题的原因，但请尝试clearing the react-native cache，如果这不起作用，您的 package.json 中的依赖树可能有问题.
