material-ui - Uncaught TypeError : Object(. ..) 在导入@material-ui/pickers 时不是函数

Question

我正在使用 "@material-ui/core": "^3.9.3"与 "@material-ui/pickers": "^3.0.0-beta.1"
当我从 @material-ui/pickers 导入任何东西时我得到:

Uncaught TypeError: Object(...) is not a function

确保 @material-ui/pickers是新的 npm 包，为下一个版本提供服务。它是必需的 @material-ui/core 至少 v4.0.0-beta.0

对于material-ui的旧v3版本，使用material-ui-pickers包和版本 v2.2.4
