webpack dev服务器错误 - 找不到模块

I have a node/npm/react project. I have a script "local": "./node_modules/webpack-dev-server/bin/webpack-dev-server.js" and run npm run local and I get the following error:

我有一个node / npm / react项目。我有一个脚本“local”：“。/ node_modules / webpack-dev-server / bin / webpack-dev-server.js”并运行npm run local，我收到以下错误：

Uncaught Error: Cannot find module "/Users/me/Dropbox/myStuff/aProject/site/node_modules/webpack-dev-server/client/index.js?http://localhost:8080"

未捕获错误：找不到模块“/Users/me/Dropbox/myStuff/aProject/site/node_modules/webpack-dev-server/client/index.js?http://localhost:8080”

index.js looks like:

index.js看起来像：

import { render } from "react-dom";
import React from "react";
import App from "./App";

render(<App />, document.getElementById("root"));

I have installed all of these npm modules. Why cannot a module be found?

我已经安装了所有这些npm模块。为什么找不到模块？

Oddly, I notice that even if I comment out index.js entirely, I get the same error message.

奇怪的是，我注意到即使我完全注释掉index.js，我也会收到相同的错误消息。

npm install --save-dev webpack is not enough.

npm install --save-dev webpack是不够的。

You have to install also the following: npm install --save-dev webpack-dev-server

您还必须安装以下内容：npm install --save-dev webpack-dev-server

And optionally, you can install also : npm install --save-dev webpack-dev-middleware webpack-hot-middleware

也可以选择安装：npm install --save-dev webpack-dev-middleware webpack-hot-middleware

And you should look your webpack file to set the good path

你应该看看你的webpack文件来设置好的路径
