我安装了yeoman并开始了官方文档中提供的示例.我完成了建议的操作

    yo webapp 
    bower install underscore  
    grunt

在运行grunt之后,我收到了消息

    grunt-cli: The grunt command line interface. (v0.1.9)

    Fatal error: Unable to find local grunt.

    If you're seeing this message, either a Gruntfile wasn't found or grunt
    hasn't been installed locally to your project. For more information about
    installing and configuring grunt, please see the Getting Started guide:

    http://gruntjs.com/getting-started

请注意,已经安装了grunt

    npm install -g grunt-cli

和

    npm install -g grunt

你在项目根目录中生成了Gruntfile.js,我正在运行该命令.
package.json也已生成:

    "name": "testyo",
    "version": "0.0.0",
    "dependencies": {},
    "devDependencies": {
      "grunt": "~0.4.1",
      "grunt-contrib-copy": "~0.4.1", …

用sudo cabal安装leksah安装leksah --global我得到了

7 of 12]编译Text.PrinterParser(src/Text/PrinterParser.hs,dist/build/Text/PrinterParser.o)

src/Text/PrinterParser.hs:230:42:不在范围内:`catch'无法安装ltk-0.8.0.6

这使得无法继续安装.它看起来像一个错误,但我可能是错的.

我正在使用Sinatra路由,如果可能的话,我想解释一个普通的HTTP地址作为路由中的参数:

url http://somesite/blog/archives   

路线是:

/http://somesite/blog/archives 

代码是:

get '/:url' do |u|  
(some code dealing with url)

HTTP URL中的各种"/"正在产生问题.

我找到的解决方法是仅传递上面示例中"somesite"所代表的URL部分,然后使用:

get '/:url' do |u|
buildUrl = "http://#{u}/blog/archives"
(some code dealing with url)

有没有办法直接处理完整的URL？
