我正在开发一个 React 项目，使用 Material UI React 组件。我想进口MuiThemeProvider in src/index.js像这样import MuiThemeProvider from "@material-ui/core/styles/MuiThemeProvider";
.
但我得到
找不到模块：无法解析“@material-ui/core/styles/MuiThemeProvider”
检查/node_modules/@material-ui/styles没有MuiThemeProvider。我不明白。在另一台计算机上重新安装该项目，/node_modules/@material-ui/styles包含一个MuiThemeProvider。我删除了node_modules文件夹并重新安装yarn install，但这并没有起到任何作用。
当我在另一台计算机上重新安装该项目时，它工作正常。
这些是来自的依赖项package.json

为什么它在两台机器上的安装会不同？！
