reactjs - 导入 "TypeError: Cannot read property ' 包时出现错误 "React-Magnific-Popup"object' of undefined"

Question

我正在使用 react-magnific-popup 包，但是当我从该包中导入任何内容时，出现此错误“类型错误:无法读取未定义的属性‘对象’”

./node_modules/react-magnific-popup/lib/SingleImage.js

我所做的只是将 Magnific Popup 导入某个组件，但正如我在此日志中看到的，错误出在包本身中，或者我的应用程序可能不支持此包。

我怎么解决这个问题？

Answer 1

我也面临同样的问题。我将按照以下步骤解决此问题。
1) 安装 prop-types；
2) 声明 PropTypes 'var PropTypes = require('prop-types');'进入以下文件。 i) SingleImage.js, LightBoxGallery.js, Popup.js.也更换

_react2['default'].PropTypes. into PropTypes.

适用于所有 Prop 类型。
3)重建你的项目..工作正常。
