Question

我在互联网上看到了一些关于如何使用带有expressJS的命令行为节点项目创建完整目录结构的技巧。以下是一些例子：

express express-skeleton＆lt;＆lt; http://quickleft.com/blog/getting-started-with-express-in-node

./node_modules/.bin/express -t ejs＆lt;＆lt; http://naholyr.fr/2011/08/ecrire-service-rest-nodejs-express-partie-1/

--l＆lt;＆lt; http://www.techrepublic.com/article/build-nodejs-web-applications-with-express/

但这些都不适合我。我已安装express并更新它以使用npm update express -g全局安装它，但我的终端甚至不识别命令行express。

如何使用命令行轻松构建Web应用程序框架？非常感谢

编辑：运行npm install -g express命令行时，收到以下错误消息：

Answer 1

运行npm install -g express时会得到什么输出？问题很可能是npm install -g没有安装到PATH中的某个地方。

Answer 2

npm无法在您的应用程序文件夹中创建文件夹。为您的文件夹提供足够的权限，我希望能解决您的问题。

通过终端创建完整的目录结构/骨架 - expressJS / nodeJS
