reactjs - 找不到模块 : Error: Can't resolve '@material-ui/core/styles' (when deploying to heroku)

Question

我有一个 react 应用程序并尝试将其部署到 Heroku 和运行时 git push heroku master

Module not found: Error: Can't resolve '@material-ui/core/styles'

我搜索了类似的问题并安装了最新版本的npm、node和metalial-ui
我也试过 npm install @material-ui/core ..没用。

这是完整的错误日志文件

问题已根据@samokasha 的回答解决，
解决方案正在使用npm install @material-ui/core --save
