但是安装指定版本的RUBY呢？

留个尾巴。

sqlite3的安装

sudo gem update --system

sudo gem install rails

sudo gem update rake

sudo gem install sqlite3-ruby

检查sqlite3安装后的版本

The followingstepis rarelynecessary, butitcan behelpfulif thingscontinueto

go wrong. You can verify which version of SQLite 3 your sqlite3-ruby interface

is bound to by running the following as a stand-alone program, from within

irb, or from within ruby script/console.

require 'rubygems'

require 'sqlite3'

tempname = "test.sqlite#{3+rand}"

db = SQLite3::Database.new(tempname)

puts db.execute('select sqlite_version()')

db.close

File.unlink(tempname)
