sqlite3-ruby gem在ubuntu上找不到sqlite3.h

Question

我试图在ubuntu上安装Rails，但我在安装sqlite3-ruby时遇到了问题--它显然找不到sqlite3.h。我能找到的关于这个错误的所有参考资料都表明问题在于:没有安装sqlite3头文件，或者make找不到它们。在我看来，我已经解决了这两个问题，但我仍然看到了同样的问题。

不知道这里到底发生了什么。可能是版本不匹配？这是ubuntu 10.04.1上的ruby 1.8.7，sqlite 3.6.22-1，gem 1.3.5和sqlite3-ruby 1.3.1。

david@li88-188:~$ sudo apt-get install sqlite3

请注意，/usr/include在参数列表中。

david@li88-188:~$ ls -l /usr/include/sqlite3.h

注意，这个文件就在那里。

Answer 1

不要紧。当我尝试安装另一个具有更好的错误消息的gem时，我发现并没有安装gcc本身。

Answer 2

在我的例子中，我必须安装libsqlite3-dev

sudo apt-get install libsqlite3-dev
