无法在rails入门指南中创建数据库

Question

通过标准Rails“开始”，我发现当我尝试执行“rake db：create”时，我总是得到错误

Could not find i18n-0.6.0 in any of the sources
Run `bundle install` to install missing gems.

这是我的database.yml：

development:
  adapter: mysql
  database: attitude
  username: attitude
  password: ***
  host: localhost

# 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: mysql
  database: attitude
  username: attitude
  password: ***
  host: localhost

production:
  adapter: mysql
  database: attitude
  username: attitude
  password: ***
  host: localhost

i18n出现在宝石列表i18n中。 Bundle show在/usr/lib/ruby/gems/1.9.1/gems/i18n-0.6.0上安装了i18n我看到了一些关于stackoverflow的相关问题，这些问题似乎是使用sudo bundle install的结果。我尝试创建一个新的rails项目并小心不使用该命令，但无济于事。我需要完全重新安装rails，还是我的Ubuntu安装毁了，或者是什么？

Answer 1

运行sudo gem uninstall i18n。然后再次bundle install（没有sudo）。
