Question

我一直在使用MaterialUI进行React项目。最初，我使用的是react-materialize软件包，它可以正常工作。

我安装@material-ui/core软件包以使用MaterialUI组件时，出现以下错误

Uncaught TypeError: __WEBPACK_IMPORTED_MODULE_0_react___default.a.createContext is not a function
    at Object.<anonymous> (index.min.js:40786)
    at __webpack_require__ (index.min.js:660)

Answer 1

material-ui/core v4.4.2 package将React 16.8.0声明为peerDependency。

它使用React 16中引入的新Context API。

您可以upgrade your React version to 16，也可以使用older context API使用material-ui/core版本的软件包。

未捕获的TypeError：__WEBPACK_IMPORTED_MODULE_0_react ___ default.a.createContext不是React项目中的函数
