Visual Studio 代码中的 JavaScript NPM 错误

Question

在 Visual Studio Code 中，我希望我的 javascript 程序能够通过服务器自动运行，因为我正在通过在线学习 javascript。

我尝试执行与在安装 IDE 上观看教程相同的步骤。

所以我安装了 Git 和 Node，现在当我打开 Visual Studio 时，保存 Hello World 程序后，它应该会自动运行。

所以我在终端输入:npm install然后错误来了，然后我再次输入 npm run dev 在浏览器中启动我的服务器。

i [the error in the pic is :
C:\Users\Addie\Desktop\JS\webpack-starter-master>npm install
npm WARN saveError ENOENT: no such file or directory, open 'C:\Users\Addie\Desktop\JS\webpack-starter-master\package.json'

您需要执行 npm init 为您的目录创建 package.json
