npm 运行服务器后的“MODULE_NOT_FOUND”

Question

我刚拿起一本新书 Fullstack React，在尝试运行示例应用程序时，出现找不到模块的错误。 有问题的模块显然是实时服务器。 这是错误消息。 我在 npm 运行服务器之前完成了 npm 安装，但没有成功

> live-server public --host=localhost --port=3000 --middleware=./disable-browser-cache.js

internal/modules/cjs/loader.js:892
  throw err;
  ^

Error: Cannot find module './disable-browser-cache.js'

删除node_modules和package-lock.json并运行以下npm commands ，它应该可以解决您的问题。

npm cache clean --force
npm install

然后

npm start
