获取未定义的方法'；反对'；Ruby dbi Gem中的错误

我已经安装了ruby dbi-0.4.3，正在尝试连接到SQL Server数据库。gem安装没有问题。deprecate方法正在作为gem一部分的Date.rb文件中使用。提前感谢您的帮助。 克里斯

这是我的密码：

require 'dbi'
$LOAD_PATH.unshift(File.dirname(__File__))

oConn = DBI.connect('DBI:ADO:Provider=SQLNCLI;Data Source="UPSTAIRS\SQLEXPRESS";
                      Integrated Security=SSPI;Initial Catalog=SQLClass')

oConn.disconnect if dbh

以下是我得到的错误：

我不知道

dbi

，但是

deprecate

-方法似乎来自

做一个

gem 'deprecated' 
require 'deprecated' 

---

在代码帮助的开头？

我认为这里的问题是ruby dbi库已经过时了。上一次接触图书馆是在3年前。您最好使用一个gem，它提供了类似的功能，并正确定义了依赖项。一个选项是

，正如knut所写的“dbi”需要“不推荐的”gem，但具体版本是-2.0.1。你可以在第38页看到这个

---

您可以使用4个空格缩进代码和输出，这样更易于阅读。（我编辑了您的代码）正如其他人所指出的，dbi库并没有得到很好的维护。github存储库中有许多挂起的拉取请求。如果您开始使用dbi，您可能会调查这些拉取请求中的一个是否能解决您的问题，然后只需构建您自己的gem版本正如其他人所说：dbi已经过时了。我也推荐使用sequel。我要试试这个-我会回来的-谢谢

begin
    require "rubygems"
    gem "deprecated", "= 2.0.1"
rescue LoadError
end
