internal/modules/cjs/loader.js:888 抛出错误； 问题

Question

我正在研究一个节点快递项目。 当我输入 nodemon server.js 并且终端显示以下错误消息时。 我删除了 package-lock.json 和 node_modules 文件夹并运行 npm install 来尝试解决这个问题，但它不起作用。 有人知道我该如何解决吗？

wen-yikuo@Wen-YideMacBook-Pro Backend % nodemon server.js

乍一看，您的依赖项中似乎缺少react ，因此：

npm import react

应该做的伎俩。

如果不是这样，我怀疑这是其中之一在您的app.js丢失或拼写错误的问题：

const soldierRoutes = require('./routes/soldierRoutes');
const soldierController = require('./controllers/soldierController');

和/或其他文件中的module.exports之一。
