这些是我遵循的步骤：

1. npm install material-components-web
2. 在我的“ resources / sass / app.scss”中，我使用此代码@import '~material-components-web/material-components-web导入了它；
3. 在我的“ resources / js / app.js”中，我添加了此代码window.mdc = require("material-components-web/dist/material-components-web"); window.mdc.autoInit();
4. 然后我运行npm run watch;
5. 然后我得到这个错误：
