[email protected] requires a peer of webpack@^4.x.x but none is installed. You must install peer dependencies yourself.
回答by Tholle
webpack-dev-serverhas Webpack as a peer dependency, which means that you are responsible for installing that yourself.
webpack-dev-server将 Webpack 作为对等依赖项，这意味着您有责任自己安装它。
You could install the latest version of Webpack and add it to your devDependencieswith the following command:
您可以安装最新版本的 Webpack 并将其添加到您devDependencies的以下命令中：
npm i -D webpack@latest
By writing webpack-dev-serveryou are also trying to use the globally installed version of that package. You can use the locally installed one instead by adding it to a script in your package.json:
通过编写，webpack-dev-server您还尝试使用该软件包的全局安装版本。您可以使用本地安装的，而是将其添加到您的脚本中package.json：
{
"scripts" : {
"start": "webpack-dev-server"
}
}
