Question

我使用Ruby22-x64只是为了让您知道，但我在命令提示符下使用gem install RedCloth成功安装了RedCloth-4.2.9。当我尝试require 'rubygems'时，我得到=>false这是正常的，因为它已经加载了，但是当我尝试require 'RedCloth时，我得到以下错误代码：

irb(main):001:0> require 'RedCloth'
LoadError: cannot load such file -- 2.2/redcloth_scan

Couldn't load 2.2/redcloth_scan

The $LOAD_PATH was:

我不知道RedCloth的版本是否可以这样做？还是某种路径错误？我真的在寻找一些帮助！请！

我必须通过创建一个@RequestMapping(value="/hadoop" , method = RequestMethod.GET) public String hadoop(ModelMap model) throws URISyntaxException, IOException { String result = null; Configuration conf = new Configuration(); FileSystem fs = FileSystem.get( new URI("hdfs://myhost:9000"), conf); Path file = new Path("/user/michael/input/input1.txt"); FSDataInputStream getIt = fs.open(file); BufferedReader d = new BufferedReader(new InputStreamReader(getIt)); String s = ""; while ((s = d.readLine()) != null) { result += s; } d.close(); fs.close(); model.addAttribute("result", result); return "hello"; }文件夹来包含2.2来改变路径，然后我才能使用它！
