ruby1.9.2 install on the window xp
1:在公司上網是有windows代理的(ntlm),而rails又都是gem安裝，對于接觸rails不多的人來時真是一場災難，我是在網站上google了半天才將rails的依賴一個一個的安裝上，然后按照上了rails2.3.3；
2：安裝后，http://localhost:3000可以看到，但是click "About your application's environment"是一直提示錯誤。

安裝sqlit3-ruby后，還是一直提示錯誤。后來使用proxy，
gem install sqlite3-ruby #在線安裝，提示
Successfully installed sqlite3-1.3.3-x86-mingw32
Successfully installed sqlite3-ruby-1.3.3
2 gems installed
這樣就ok了。
==========20110420补充
在另一台windowxp上重新安装又是出错
最后终于发现原来是要安装sqlite3-1.3.3-x86-mingw32.gem才可以
