问题描述

我刚升级到雪豹.以前，我一切运行正常，但是现在从终端启动服务器时，我得到:

I just upgraded to snow leopard. Before, I had everything running fine, but now when I start the server from the terminal I get:

=> Booting WEBrick
=> Rails 2.3.3 application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
[2009-08-28 23:18:19] INFO  WEBrick 1.3.1
[2009-08-28 23:18:19] INFO  ruby 1.8.7 (2008-08-11) [universal-darwin10.0]
[2009-08-28 23:18:19] INFO  WEBrick::HTTPServer#start: pid=845 port=3000

然后，当我进入生成的页面时，它似乎无法与sqlite3一起使用.我该如何解决?这是我进入脚本视图页面时服务器输出的内容:

Then when I got to generated page, it seems like it isn't working with sqlite3. How do I fix? Here's what the server prints out when I go to a scripted view page:
