sqlite3-ruby gem在ubuntu上找不到sqlite3.h

Trying to get Rails up on ubuntu, and I’m having trouble installing sqlite3-ruby – it apparently can’t find sqlite3.h. All the references I can find to the error suggest the problem is either: sqlite3 headers aren’t installed, or make can’t find them. It looks to me like I’ve solved both those issues and I’m still seeing the same problem.

试图在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，我仍然看到同样的问题。

No real idea what’s going on here. Version mismatch, maybe? This is with ruby 1.8.7, sqlite 3.6.22-1, gem 1.3.5 and sqlite3-ruby 1.3.1 on ubuntu 10.04.1.

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。

#1

In my case I had to install libsqlite3-dev

在我的情况下，我不得不安装libsqlite3-dev

sudo apt-get install libsqlite3-dev

#2

Never mind. gcc itself wasn't installed, as I discovered when I tried to install another gem with better error messages.

没关系。 gcc本身没有安装，正如我在尝试安装另一个带有更好错误消息的gem时发现的那样。
