其实当ruby安装成功后,然后在gem install --no-ri --no-rdoc rails的时候,报出了下面的错误:

Building Nokogiri with a packaged version of libxml2-2.9.2 |

with the following patches applied: |

Team Nokogiri will keep on doing their best to provide security |
|
34 |
updates in a timely manner, but if this is a concern for you and want |
|
35 |
to use the system library instead; abort this installation process and |
|
36 |
reinstall nokogiri as follows: |
|
38 |
gem install nokogiri -- --use-system-libraries |
|
39 |
[--with-xml2-config=/path/to/xml2-config] |
|
40 |
[--with-xslt-config=/path/to/xslt-config] |
|
42 |
If you are using Bundler, tell it to use the option: |
|
44 |
bundle config build.nokogiri --use-system-libraries |
|
47 |
Note, however, that nokogiri is not fully compatible with arbitrary |
|
48 |
versions of libxml2 provided by OS/package vendors. |

解决办法如下:
yum -y install libxml2 libxslt libxml2-devel libxslt-devel
gem install nokogiri -- --use-system-libraries
gem install rails
执行上面的步骤,就可以正常安装rails了.
