如何修复错误nodejs express cannot find module./response

Question

当我运行命令时

$ npm 开始

这出现了

> assignment3@1.0.0 start
> nodemon server.js

[nodemon] 2.0.12
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*
[nodemon] watching extensions: js,mjs,json
[nodemon] starting `node server.js app.js`
node:internal/modules/cjs/loader:936
  throw err;
  ^

我试图在 node_modules/express/lib/express.js 中搜索，发现没有文件。

./响应响应.js

不知道从哪里开始，我会重新安装 node_modules 或者你有一些想法来修复这种错误，希望你能帮助我。

Answer 1

您应该尝试重新安装 express：

rm -rf node_modules && npm i

之所以如此，是因为 Express 似乎确实在这里有响应文件： https://github.com/expressjs/express/blob/master/lib/response.js 。

PS：发帖，因为我不能评论。

Answer 2

重新安装 express 最终会解决问题。
