Question

安装并尝试在Mac OS X 10.5.8上运行Geocommons geocoder后，有没有人遇到过以下错误？这是我从终端窗口开始的确切输出，从我开始irb：

$ irb
>> require 'geocoder/us'
=> true
>> db = Geocoder::US::Database.new("/opt/tiger/orangeca.db")
=> #<Geocoder::US::Database:0x57ac10 @threadsafe=false, @db=#<SQLite3::Database:0x57ab98>, @debug=false, @st={}>
>> p db.geocode("Disneyland Anaheim, CA 92802")

from (irb):3>>

顺便提一下，“orangeca.db”是加利福尼亚州奥兰治县的TIGER / Line数据 - 我只从主要的Census数据库而不是整个美国数据集下载它，因为我只是测试Geocoder对一个软件的用处我想写，我不想花10个小时下载几GB的数据，我最终可能不会在最终产品中使用这些数据。

根据我在SQLite3 :: Database :: FunctionProxy类中找到的信息，我最好的解释这个行为的猜测如下：

我的SQLite3安装正确，但是配置错误，导致我的Geocoder没有找到所需的set_result。
我的SQLite3安装不正确，但我不确定在设置时出错了。

如果有人能提供任何帮助，我将不胜感激。提前感谢您的帮助！

Answer 1

尝试使用此版本的Sqlite Ruby Gem：http://github.com/schuyler/sqlite3-ruby

Answer 2

您需要使用sqlite3-ruby gem的1.2.5版本。

gem install sqlite3-ruby --version=1.2.5

您可以确保没有其他宝石提供sqlite3（例如sqllite3或更新版本的sqllite3-ruby）或明确要求此版本的此宝石。

在Mac OS X 10.5.8上使用irb运行Geocommons Geocoder时SQLite3中的NoMethodError（set_result）
