您好，我尝试运行您的代码，npm install成功无错误，但npm start server输出如下：

> compiler@0.1.0 start /home/newcoderlife/Compiler-Principle
> node index.js "server"

根据错误信息，我运行了sudo npm install koa -g，仍旧报错。

希望能够得到您的帮助，谢谢！

请问您是在 Windows 10 环境下运行，还是在 WSL 环境下呢？

通过安装一系列的koa相关包，现在npm run server不报错，但是npm run dev报错，错误信息如下:

> compiler@0.1.0 dev /home/newcoderlife/Compiler-Principle
> cd view && npm start


> compiler@0.1.0 start /home/newcoderlife/Compiler-Principle/view
> webpack-dev-server --hot --inline --color --hot --config ./scripts/webpack.dev.js

The CLI moved into a separate package: webpack-cli
Please install 'webpack-cli' in addition to webpack itself to use the CLI
-> When using npm: npm i -D webpack-cli
-> When using yarn: yarn add -D webpack-cli

请问我是否仍然缺少一些依赖包？谢谢！

非常抱歉，从错误提示来看，你需要安装 webpack-cli
