在OS X Lion上与sqlite3 gem苦苦挣扎 [英] Struggling with sqlite3 gem on OS X Lion

问题描述

我是Mac和Ruby on Rails的新手，我正在尝试设置我的环境.我一直在研究本教程，并且一直试图在Mac OS X Lion上安装sqlite3 gem.

I'm new to Mac and Ruby on Rails and I'm trying to set up my environment. I've been working through this tutorial and am stuck trying to get the sqlite3 gem installed on Mac OS X Lion.

• Xcode 4.2.1
• git版本1.7.5.4
• Ruby 1.9.3p0
• gem -v结果为1.8.11
• sqlite版本3.7.5

当我尝试运行 gem install sqlite3 或 gem install sqlite3---with-sqlite3-dir =/usr/bin 时，出现以下错误文本，有人有什么建议吗?

When I try to run gem install sqlite3 or gem install sqlite3 -- --with-sqlite3-dir=/usr/bin I get the error text below, does anyone have any suggestions?

推荐答案

您将需要sqlite3库文件，我想它应该和运行一样简单

You are going to need the sqlite3 library files, which I imagine should be as simple as running

 sudo brew install libsqlite3-dev
