Rails 3.0.3-Oracle_enhanced不起作用 [英] Rails 3.0.3 - Oracle_enhanced doesn't work
问题描述
我一直在使用带有oracle_enhanced的Ruby 1.8 + Rails 2.3.5，并且运行良好.
I have been using Ruby 1.8 + Rails 2.3.5 with oracle_enhanced and it works fine.
现在，我最近在另一个文件夹上安装了Ruby 1.9.2和Rails 3.0.3，但我无法使其正常工作.
Now I recently installed Ruby 1.9.2 and Rails 3.0.3 on another folder, and I can't get it to work.
当我创建一个简单的应用程序并访问它时，页面返回以下错误:
When I create a simple application and access it, the page returns the following error:
请安装oracle_enhanced 适配器:
gem install activerecord-oracle_enhanced-adapter(没有要加载的文件- active_record/connection_adapters/oracle_enhanced_adapter)
Please install the oracle_enhanced adapter:
gem install activerecord-oracle_enhanced-adapter(no such file to load -- active_record/connection_adapters/oracle_enhanced_adapter)
我试图调查问题，发现Ruby使用的文件夹为C:\ Ruby192 \ lib \ ruby \ gems \ 1.9.1 \ gems \ activerecord-3.0.3 \ lib \ active_record \ connection_adapters.该文件夹中没有oracle_enhanced_adapter.br文件.
I tried to investigate the problem and found the folder Ruby is using, which is C:\Ruby192\lib\ruby\gems\1.9.1\gems\activerecord-3.0.3\lib\active_record\connection_adapters. In that folder there is no oracle_enhanced_adapter.br file.
该文件位于另一个文件夹C:\ Ruby192 \ lib \ ruby \ gems \ 1.9.1 \ gems \ activerecord-oracle_enhanced-adapter-1.3.1 \ lib \ active_record \ connection_adapters中.我尝试将所有rb文件从该文件夹复制到另一个文件夹，但仍然出现错误，但更改了:
The file is in another folder, C:\Ruby192\lib\ruby\gems\1.9.1\gems\activerecord-oracle_enhanced-adapter-1.3.1\lib\active_record\connection_adapters. I tried to copy all rb files from this folder to the other one, I still got an error but it changed:
请安装oracle_enhanced 适配器:
gem install activerecord-oracle_enhanced-adapter(错误:ActiveRecord oracle_enhanced 适配器无法加载ruby-oci8 图书馆.请安装ruby-oci8 宝石.)
Please install the oracle_enhanced adapter:
gem install activerecord-oracle_enhanced-adapter(ERROR: ActiveRecord oracle_enhanced adapter could not load ruby-oci8 library. Please install ruby-oci8 gem.)
我注意到我以前的Ruby安装(1.8)具有相同的文件/文件夹结构，并且oracle_enhanced可以工作.
I noticed that my old Ruby install (1.8) has the same file/folder structure, and oracle_enhanced works.
如果我在IRB上手动测试连接可以正常工作，则问题仅在于Rails.
If I test the connection manually on IRB it works fine, the problem is only with Rails.

推荐答案
在Rails 3中，您必须在Gemfile中指定所有gem依赖项.请参阅带有ruby-oci8和oracle_enhanced适配器的Gemfile示例: https://github.com/rsim /rails3_oracle_sample/blob/master/Gemfile
In Rails 3 you have to specify all your gem dependencies in Gemfile. See example of Gemfile with ruby-oci8 and oracle_enhanced adapter: https://github.com/rsim/rails3_oracle_sample/blob/master/Gemfile
在Gemfile中指定了gem依赖关系后，您需要运行bundle install以确保已安装所有必需的gem.之后，您应该可以使用oracle_enhanced适配器.
After specifying your gem dependencies in Gemfile you need to run bundle install to ensure that all necessary gems are installed. After that you should be able to use oracle_enhanced adapter.
