我正在尝试在OS X 10.6上安装“sqlite3-ruby”gem（或“sqlite3”gem）。我正在使用ruby-1.9.2，我目前得到以下内容：
$ sqlite3 --version
3.7.4
$ sudo gem install sqlite3

以下是其结果＆amp; whereis，sqlite3.h位于/ opt / local / include：
$ which sqlite3

我也试过传递以下内容：
sudo gem install sqlite3 -- --with-sqlite3-include /opt/local/include --with-sqlite3-lib /opt/local/lib
sudo gem install sqlite3 -- --with-sqlite3-dir /opt/local/bin
导致以下结果：

也在/Users/folken/.rvm/gems/ruby-1.9.2-head/gems下： sqlite的，红宝石2.2.3 sqlite3-1.3.3
在RVM下我有ruby-1.8.7并且sqlite3 gem加载得很好，但经过大量的谷歌搜索后我还没有找到适合我的解决方案。非常感谢任何帮助（即使它涉及手动安装/ hackery以便工作）。

我遇到的问题与我安装sqlite3的问题几乎相似，但sqlite3 gem无法安装。我看到如下错误消息，
user-name-rajas-macbook-pro:rails3 user-namer$ gem install sqlite3
Building native extensions. This could take a while...
ERROR: Error installing sqlite3:
ERROR: Failed to build gem native extension.

checking for sqlite3_libversion_number() in -lsqlite3... no
sqlite3 is missing. Try 'port install sqlite3 +universal'
or 'yum install sqlite3-devel' and check your shared library search path (the
location where your sqlite3 shared library is located).

这对我有用
gem install sqlite3 -- --with-sqlite3-dir=/opt/local
答案 1 :(得分：6)
我使用ruby 1.9.2.p180和使用Mac OS X 10.5.8（Leopard）的rails 3.1.0.rc6跟踪rv3的动作书中的Rails3，当我跑步时：
rake cucumber:ok
我得到了：
Please install the sqlite3 adapter: `gem install activerecord-sqlite3-adapter` (can't activate sqlite3 (~> 1.3.4, runtime), already activated sqlite3-1.3.3. Make sure all dependencies are added to Gemfile.)
gem install sqlite3 -- --with-sqlite3-dir=/opt/local
其次是：
bundle install
希望在需要sqlite 1.3.5时，我会在互联网上找到自己的答案。

听起来你还没有安装过XCode。
答案 3 :(得分：2)
对于osx，请确保已安装Xcode并且您已接受这些条款。对我来说，我没有同意这些条款（无论出于何种原因，最近Xcode最近在我的电脑上安装或更新）。
