在Windows 10上安裝Node.js包（和npm）我無法知道如何安裝

Question

當我啓動'npm start'時它給出了以下錯誤。而localhost：8082不能正常工作。我嘗試了localhost：8080，但沒有任何工作。

$ npm start

Answer 1

請確保文件「D：\ myangular \ package.json」存在。另一種方法是，嘗試刪除node_modules文件夾並運行命令：npm install。然後重新運行你的命令：npm start。

Answer 2

請先運行npm install命令。比你跑node your main file.js
