【问题描述】：

运行简单的命令

rails g model User

导致：

→ bundle exec rails g model User
      invoke  active_record
      create    db/migrate/20160128191020_create_users.rb
      create    app/models/user.rb
      invoke    rspec
      create      spec/models/user_spec.rb
      invoke      factory_girl
      create        /spec/factories/users.rb

省略其余部分。

我正在使用 factory girls rails。 spec 和 spec/factories folders' 权限为 drwxr-xr-x（755，更改为 777 无效）。重新安装factory_girl_rails 没有效果。 Ruby 2.2.2（已经试过不同的版本）

Tired this, no effect

【问题讨论】：

/spec/factories/users.rb 是问题所在，它试图在根目录下创建spec 目录。但是为什么会这样呢？ :)
有没有机会为“FactoryGirl.definition_file_paths”设置一个值？看起来“/spec/factories”的值已经覆盖了“spec/factories”（即根级别而不是相对于当前文件夹）。

【解决方案1】：

也许你做到了：

# config/application.rb
config.generators do |g|
  g.fixture_replacement :factory_girl, dir: "/spec/factories"
end

如果是这样，您需要将其从“/spec/factories”更改为“spec/factories”

参考：https://github.com/everydayrails/rails-4-1-rspec-3-0/blob/master/config/application.rb

【解决方案2】：

您需要授予系统根用户访问所需目录的权限

sudo chmod 777 -R your_project_directory_to_be_access

在您的情况下，您可以使用：

sudo chmod 777 -R /spec/

出于安全原因，请记住：

chmod 777 赋予每个人读、写和执行权限，这对于大多数问题来说绝对是太多了。
