sqlite3-ruby gem在ubuntu上找不到sqlite3.h [英] sqlite3-ruby gem can't find sqlite3.h on ubuntu

问题描述

试图在Rails上安装Rails，而我在安装sqlite3-ruby时遇到了麻烦-显然找不到sqlite3.h.我可以找到的所有对该错误的引用都表明问题是:未安装sqlite3标头，还是make找不到它们.在我看来，我已经解决了这两个问题，而且仍然遇到相同的问题.

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.

不知道这是怎么回事.版本不匹配，也许吗?这是Ubuntu 1.0.04.1上的ruby 1.8.7，sqlite 3.6.22-1，gem 1.3.5和sqlite3-ruby 1.3.1.

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.

请注意，/usr/include在参数列表中.

Note that /usr/include is in the list of arguments.

请注意，文件在那里.

推荐答案

没关系.正如我在尝试安装具有更好错误消息的另一个gem时发现的那样，没有安装gcc本身.

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