Ruby on rails Can'；t安装sqlite

我用mac

Gem版本：2.4.5.1 Ruby版本：Ruby 2.2.3p173（2015-08-18修订版51636）[x86_64-darwin15] 档案：

我花了大约3个小时寻找解决方案，但运气不佳

我读了迈克尔·哈特尔的《RubyonRails教程》，第46页

第一个错误导致另一个错误，导致另一个错误

它以以下命令开始：

bundle install --without production

这将导致此错误：

An error occurred while installing sqlite3 (1.3.5), and Bundler cannot
continue.
Make sure that `gem install sqlite3 -v '1.3.5'` succeeds before bundling.

得到这个错误，我不知道该怎么办：

系统中是否安装了SQLite3

如果您正在使用MacPorts：

sudo端口安装sqlite3

或Brew：

brew安装sqlite3
请按如下方式尝试安装：

gem安装sqlite3-v'1.3.5'--srcdir=/usr/local/mysql/include
