尝试在ubuntu上获取Rails,我在安装sqlite3-ruby时遇到问题 - 显然找不到sqlite3.h
。我可以找到错误的所有引用都表明问题是:未安装sqlite3头文件,或者make无法找到它们。在我看来,我已经解决了这两个问题,我仍然看到了同样的问题。
不知道这里发生了什么。版本不匹配,也许?这是在ubuntu 10.04.1上使用ruby 1.8.7,sqlite 3.6.22-1,gem 1.3.5和sqlite3-ruby 1.3.1。

在我的情况下,我必须安装libsqlite3-dev

没关系。 gcc本身没有安装,正如我在尝试使用更好的错误消息安装另一个gem时发现的那样。
