npm 开始在 node.js 中给出错误

我对 Node.js 和 mongodb 完全陌生。我正在使用以下链接：http://cwbuecheler.com/web/tutorials/2013/node-express-mongo/ http://cwbuecheler.com/web/tutorials/2013/node-express-mongo/这个过程运行得非常好并且得到了完全相同的结果。但突然间“npm start”停止工作了。 我卸载了所有东西并尝试从本教程中给出的步骤 1 重新安装。当我发出命令“npm install -g express”时，我没有得到任何 http 304 和 GETS 的列表！ 。 当我忽略并继续该过程时，我发出命令 npm start ，但它不起作用。显示的错误如下所示 C:\project\nodetest1>npm 启动

请帮忙 。提前致谢。

该错误表明未找到./bin/www 目录。用点指定的路径是相对于当前目录的，因此当前目录必须是 C:/project/nodetest1npm start在这种情况下工作。
