我怀疑它与“-I / Users / joshcrews / .rvm / rubies / ruby-1.8.7-p174 / lib / ruby / 1.8 / i686-darwin9.8.0”有关，因为i686-darwin9。该文件中不存在8.0

我从一个（？）sqlite3-ruby gem维护者，Aaron Patterson那里得到了Railsconf的帮助
选项：
登上Snow Leopard
sqlite3-ruby＆gt; = 1.3.0未针对OSX 10.5进行测试。雪豹应该工作
安装sqlite3-ruby 1.2.5
gem install sqlite3-ruby -v 1.2.5
然后设置每个Rails3 Gemfile来说明这个
gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'
首先通过macports安装sqlite3
sudo port install sqlite3
gem install sqlite3-ruby
答案 1 :(得分：3)
我不是百分之百确定是什么导致了这个问题，但我通过自制软件安装sqlite3来实现它：http://github.com/mxcl/homebrew
之后，宝石安装就好了。 Leopard的sqlite3版本必须与新版本的sqlite3-ruby不兼容。
答案 2 :(得分：2)
如果您已经安装了sqlite3 macport或brew，但仍然存在问题，则可能必须在安装gem时指定构建选项。
示例：
gem install sqlite3 -v 1.3.5 -- --with-sqlite3-include=/opt/local/include --with-sqlite3-lib=/opt/local/lib
如果您使用的是自制软件，请使用/ usr / local代替/ opt / local。
配置bundler以记住sqlite3的构建选项（运行“bundle help config”了解更多信息）：
bundle config build.sqlite3 --with-sqlite3-include=/opt/local/include --with-sqlite3-lib=/opt/local/lib
答案 3 :(得分：1)
我在Linux上遇到同样的问题，并运行两个命令。效果很好。
sudo aptitude install sqlite3 libsqlite3-dev
sudo gem install sqlite3-ruby
