Question

我刚刚安装了新版本的Ubuntu 10.04，并希望让我的rails项目正常运行。我检查了rails项目2.3.3并使用典型的sqlite设置填写databasye.yml文件：

# SQLite version 3.x
#   gem install sqlite3-ruby (not necessary on OS X Leopard)
development:
  adapter: sqlite3
  database: db/pictrs_development.sqlite3
  pool: 5
  timeout: 5000

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: sqlite3
  database: db/pictrs_test.sqlite3
  pool: 5
  timeout: 5000

production:
  adapter: sqlite3
  database: db/pictrs_production.sqlite3
  pool: 5
  timeout: 5000

当我跑步时：

rake db:create

我收到以下错误：

helex@mg:~/Downloads/pictrs_on_rails$ rake db:migrate
(in /home/helex/Downloads/pictrs_on_rails)
rake aborted!
no such file to load -- initializer
/home/helex/Downloads/pictrs_on_rails/Rakefile:4:in `require'
(See full trace by running task with --trace)

rake db：create --trace的输出是：

rake aborted!
no such file to load -- initializer
/usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
/usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'

/usr/lib/ruby/1.8/rake.rb:1998:in `run'
/usr/bin/rake:28

rake似乎在加载Rakefile的以下行时出现问题：

require(File.join(File.dirname(__FILE__), 'config', 'boot'))

我在ubuntu 9.10下设置了同一个项目，并且在执行rake任务时收到了错误消息，该任务告诉我为项目安装特定的gem，因此很容易修复。我创建其他新项目，他们都工作。其实我不知道在哪里寻找错误。我使用了不同的rubygems版本并尝试了google-search中的各种内容。

这是我的宝石列表：

您已安装Rails 3.0，但您正在尝试运行Rails 2.3.3项目。尝试安装与您的项目匹配的Rails版本，您可能会没事的。
