Ruby on rails 安装sqlite3 1.3.9 gem时出错

我正在升级到rails 4，但在运行bundle install时遇到以下问题

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

    /Users/user/.rvm/rubies/jruby-1.7.4/bin/jruby extconf.rb

当我运行'gem install sqlite3--version 1.3.9'时，我收到了相同的错误。有人知道为什么会这样吗？

试试这个：

$ sudo apt-get install sqlite3 libsqlite3-dev
$ bundle install

即使在删除并重新安装sqlite3之后，我也会遇到完全相同的错误。
