首先,我在這裏發現了許多類似的主題,但即使在提及它們之後,我仍然無法完成它的工作。我的webpack-dev-middleware設置無法獲取/錯誤
所以,我的問題只是當我在運行我的快遞服務器(使用npm run serve
)後訪問localhost:3000
時,我在Chrome中獲得Cannot GET /
。這並不是說它無法找到bundle.js文件;它根本找不到index.html。
當我在package.json文件中運行npm run serve
腳本時,我在服務器控制檯上看不到任何錯誤。 Webpack構建(從Webpack-dev-middleware調用)日誌也不會顯示錯誤。
如果我直接從終端運行webpack-dev-server並訪問相同的URL,它會正常工作。 (我在webpack.config.js
覆蓋了主機和端口,以配合我使用的Express服務器的那些,通過devServer
選項。)
我在做什麼錯?

你的'npm run serve'腳本是什麼? –
@LeeHanKyeol'nodemon server/server.js' –
你說的是'開發'(而不是'生產')環境? –
