TypeError：无法读取未定义（材料ui）的属性“ isRequired”

Question

我尝试从@material-ui/core@3.9.3切换到材料v4.4.3的最新版本，但出现此错误

对于我来说，尚不清楚此问题发生在哪个代码段中以及如何解决。也许有人对此有想法？另外，您可以在package.json文件中检查我所有的依赖项。请让我知道您需要哪些信息（如果不清楚），我会附上它。

Answer 1

我只是遇到了同样的问题。更新道具类型包对我有用。我使用的是版本prop-types@15.6.0，但是材料v4将prop-types@^15.7.2声明为依赖项。因此，请尝试在您的应用程序中全新安装prop-types。这对我有用。

  npm uninstall prop-types;
  npm install --save-exact prop-types@15.7.2;

我如何知道的： 如果您单击SelectInput.js：361，它将带您进入这一行

哪个解析为prop-types包。

希望这会有所帮助

尝试一下

import {PropTypes} from "prop-types";
