node.js - 无法在 Ubuntu 中使用 Express.js

Question

我安装了 node 和 npm，然后我安装了 express gobally 和本地。我正在关注本教程。

但是当我输入命令 express 或 express -c stylus 时，它会询问 Destination is not empty？然后它说正在中止。

但是，该包已创建。

abhishek@TiltedLines:~/blog$ express mytestapp

   create : mytestapp
   create : mytestapp/package.json
   create : mytestapp/app.js
   create : mytestapp/public
   create : mytestapp/public/images
   create : mytestapp/public/stylesheets
   create : mytestapp/public/stylesheets/style.css
   create : mytestapp/routes
   create : mytestapp/routes/index.js
   create : mytestapp/views
   create : mytestapp/views/layout.jade
   create : mytestapp/views/index.jade
   create : mytestapp/public/javascripts

   dont forget to install dependencies:
   $ cd mytestapp && npm install

abhishek@TiltedLines:~/blog$ express -c stylus

Answer 1

您希望将选项作为您运行的单个快速生成器的一部分运行，而不是作为单独的调用。从您的示例输出中，您将在 mytestapp 下生成一个应用程序。然后在运行 express -c stylus 时在上一级创建的 css 样式来自生成的 mytestapp 外部的命令目录。

尝试在空目录中运行以下命令:

express -c stylus mytestapp

这将使用手写笔 css 引擎创建您的应用程序。
