我是NodeJS的新手,我正在尝试使用快速和快速生成器。我已经使用命令安装了express:
C:\project>npm install -g express
然后我安装了快速发电机模块:
C:\project>npm install -g express-generator
然后我为项目创建一个文件夹并安装de dependencies:
C:\project\express> nodetest1
C:\project\nodetest1>npm install
那里的一切正常,但是当我尝试使用以下命令启动服务器时出现问题:
C:\project\nodetest1>npm start
似乎服务启动但是一旦启动它就会关闭,结果:
> nodetest1@0.0.0 start C:\project\nodetest1
> node ./bin/www
C:\project\nodetest1>
当我尝试打开 localhost:3000 时,它不起作用。我在网上搜索,我还没有找到解决方案,有人可以指导我如何解决这个问题吗?
谢谢。

你需要检查你的package.json npm start
正在做什么。它应该有启动你的应用程序的命令,它应该有一个看起来像这样的部分:
"scripts": {
"start": "node app.js"
},
app.js应该由生成器创建,但是根据您描述的步骤,您似乎忘记生成应用程序。试试这个:
express mynewapp
cd mynewapp
npm install
npm start

您可以轻松解决此问题。转到" packages.json"文件然后更改开始:
"scripts": {
"start": "node ./bin/www"
}
并使其"开始":"节点app.js" 。然后运行命令 npm start ,项目无法运行。现在返回并再次将开始更改为" start":" node ./bin/www" 这是默认值快速并运行命令, npm start。它对我有用。

尝试http://www.npmjs.com/package/gennode,这是用于Node.js项目的非常简单的代码生成器模块。杂物控制器,路线,测试和文档将自动为您生成。因此,您只需要专注于使服务器独特的功能即可。
