脚本/控制台不起作用;报道“缺少Rails宝石。请`gem install -v = rails` ..."即使轨道显示为已安装 [英] script/console won't work; reports "Missing the Rails gem. Please `gem install -v= rails`..." even though rails shows as installed

问题描述

正在加载开发环境（Rails 2.3.5）
缺少对应的脚本/控制台失败Rails宝石。请 gem install -v = rails ，在config / environment.rb中更新您安装的Rails版本的RAILS_GEM_VERSION设置，或者注释掉RAILS_GEM_VERSION以使用安装的最新版本。

gem list 和 sudo gem list show导轨（2.3.5）安装。另外，脚本/服务器工作正常。我发现一些消息来源表示这个问题可能与rack（1.1.0）有关，所以我恢复到了1.0.1，但它没有帮助。

I 'd爱你们有的任何建议，因为我甚至想在我看到迄今为止的简短内容之后学习RoR。

编辑：@ zed_0xff：

好的，这是 ./ script / console --trace 的结果：

  /usr/lib/ruby/1.8/optparse.rb:1450:in`complete'：无效选项：--trace（OptionParser :: InvalidOption）$ b $ from /usr/lib/ruby/1.8/optparse.rb:1448:in`catch'$ b $ from /usr/lib/ruby/1.8/optparse.rb:1448:in`complete'

以下是 rake db：migrate的结果--trace ：

 **调用环境（first_time）
 **执行环境
 **执行db：migrate

 **调用环境
 **执行db：schema：dump 
  

这有帮助吗？

编辑＃2：@ zed_0xff：

rake gems ：

在/ home / carpdiem / Dropbox / programming / ruby​​ / rails_projects / demo_app）
$ b $ I =已安装
F =已冻结
R =框架（在rails开始之前加载）`

config / environment.rb：

`require File.join（File.dirname（ File ），'boot '）

Rails :: Initializer.run do | config |
config.time_zone ='UTC'
end`

编辑＃3：我修正了它！这听起来像是有一些复杂的依赖性问题。遵循以下建议： http://docs.heroku.com/rails236 升级到rails 2.3 .8似乎已经解决了这个问题。 脚本/控制台现在正确启动。 code> ./ script / console --trace 或 rake db：migrate --trace ，rake命令可能会失败，但 - 跟踪开关可以为您的应用失败提供有价值的信息。

I'm trying to learn RoR, and running script/console fails, returning:

Loading development environment (Rails 2.3.5) Missing the Rails gem. Please gem install -v= rails, update your RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do have installed, or comment out RAILS_GEM_VERSION to use the latest version installed.

Both gem list and sudo gem list show rails (2.3.5) as installed. Additionally, script/server works fine. I found some sources that suggested the problem might be with rack (1.1.0), so I reverted back to 1.0.1, but it didn't help.

I'd love any suggestions you guys have, because I really want to learn RoR after even the brief bits I've seen so far.

EDIT: @zed_0xff:

All right, here's the result of ./script/console --trace:

/usr/lib/ruby/1.8/optparse.rb:1450:in `complete': invalid option: --trace (OptionParser::InvalidOption)
    from /usr/lib/ruby/1.8/optparse.rb:1448:in `catch'
    from /usr/lib/ruby/1.8/optparse.rb:1448:in `complete'
    from /usr/lib/ruby/1.8/optparse.rb:1261:in `parse_in_order'
    from /usr/lib/ruby/1.8/optparse.rb:1254:in `catch'
    from /usr/lib/ruby/1.8/optparse.rb:1254:in `parse_in_order'
    from /usr/lib/ruby/1.8/optparse.rb:1248:in `order!'
    from /usr/lib/ruby/1.8/optparse.rb:1339:in `permute!'
    from /usr/lib/ruby/1.8/optparse.rb:1360:in `parse!'
    from /var/lib/gems/1.8/gems/rails-2.3.5/lib/commands/console.rb:11
    from /usr/lib/ruby/1.8/optparse.rb:791:in `initialize'
    from /var/lib/gems/1.8/gems/rails-2.3.5/lib/commands/console.rb:6:in `new'
    from /var/lib/gems/1.8/gems/rails-2.3.5/lib/commands/console.rb:6
    from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
    from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require'
    from ./script/console:3

And here's the result of rake db:migrate --trace:

(in /home/carpdiem/Dropbox/programming/ruby/rails_projects/demo_app)
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:migrate
** Invoke db:schema:dump (first_time)
** Invoke environment 
** Execute db:schema:dump

Does that help?

EDIT #2: @zed_0xff:

rake gems:

`(in /home/carpdiem/Dropbox/programming/ruby/rails_projects/demo_app)

I = Installed F = Frozen R = Framework (loaded before rails starts)`

config/environment.rb:

`require File.join(File.dirname(File), 'boot')

Rails::Initializer.run do |config| config.time_zone = 'UTC' end`

EDIT #3: I fixed it! It sounds like there was some complicated dependency issues at fault. Following the suggestion from here: http://docs.heroku.com/rails236 to upgrade to rails 2.3.8 seems to have resolved the problem. script/console starts up correctly now.

解决方案

try to run ./script/console --trace or rake db:migrate --trace, rake command will likely fail too, but --trace switch can provide you a valuable information where your app fails.
