1.問題：

module.js:538
    throw err;
    ^

Error: Cannot find module 'webpack/bin/config-yargs'
    at Function.Module._resolveFilename (module.js:536:15)

2.原因

當webpack與webpack-dev-server版本不匹配時，會出現如上錯誤。具體版本如下：

webpack-dev-server與webpack應該成對匹配使用，webpack4.x匹配webpack-dev-server3.x，webpack5.x匹配webpack-dev-server2.x，博主用的時候是最新版本5.x，無法與webpack-dev-server3.x相容(圖中已刪除webpack-dev-server3.x)

3.解決方法

3.1 解除安裝本地舊包

cnpm uninstall webpack-dev-server --save-dev 
 

3.2 重新下載一對匹配的依賴，這裡舉個跑通了的例子

cnpm install --save-dev [email protected]
cnpm install --save-dev [email protected]

重啟webpack-dev-server，成功跑通
