node.js - Node 。并且 npm start 不起作用

Question

标题说明了大部分问题。当我尝试运行 node . 我得到:

    module.js:340
    throw err;
          ^
Error: Cannot find module 'static-favicon'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)
    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:902:3

实际上似乎没有模块文件夹。我只是在一个空目录中运行 express

npm 但是工作正常。如果重要的话，这是一个全新的快速安装。任何帮助都会很棒，谢谢!

Answer 1

使用express-generator生成 Node 应用程序后，需要为项目安装依赖。这是通过:

$ npm install

完成后，您可以使用 npm 启动应用程序:

$ npm start

默认情况下，快速生成的应用程序将此声明为 npm 的 start 命令(您可以在 package.json 文件中查看):

"start": "node ./bin/www"

所以要通过命令行执行相同的操作，您需要运行:

$ node ./bin/www
