IconComponent: PropTypes.elementType.isRequired ( material ui )错误

Question

我曾尝试将material ui从v3迁移到v4，但遇到了此问题

​

​

​

​

我认为这个问题与Select组件的prop IconComponent有关，但在将其添加到项目中的每个@material-ui/core/Select组件后，它并没有帮助。

另外，我在material ui github存储库https://github.com/mui-org/material-ui/pull/17390/files中发现了这种变化，也许它会有所帮助

你也可以在下面找到我的所有依赖项：

Answer 1

是在prop-types 15.7.0中添加的，而您正在使用15.6.2

将prop-type升级到15.7.0或更高版本，错误应该会消失。
