我做railstutorial的草案版本，当我尝试运行bundle exec rake test:models我收到此错误信息：束EXEC耙测试：机型抛出变量Errno :: EACCES：权限被拒绝

我已经尝试检查我的db文件夹的权限，并试图重新启动一切。我在Windows上使用rails版本4.2.0beta1。当我制作“用户”模型时，问题就开始了。我试着回滚，并再次迁移。

编辑： 看来我的测试数据库以某种方式损坏了。如果我将/config/database.yml测试更改为/db/development.sqlite，则测试工作正常。

我删除了旧的test.sqlite3，并将其替换为一个development.sqlite3的副本，并将其重命名为test.sqlite3，这似乎解决了这个问题。

嗯它也解决了我的问题，但问题是为什么它的发生 – Dexture 2014-11-27 10:15:29

是的，我也想知道这一点，它不断发生的定期和此修复似乎只是对实际问题的症状临时破解。但是我最近把我的开发从windows 8改成了kubuntu，而且我还没有再次体验过它。 @Dexture你的操作系统是什么？知道它是否真的是一个Windows问题可能有助于理解“为什么”... – madstap 2014-11-27 19:50:33

窗口，但昨晚我终于在虚拟机上安装Fedora。这就是为什么大多数开发人员更喜欢窗口的轨道。 – Dexture 2014-11-28 06:18:24

在运行测试之前运行rake db:migrate RAILS_ENV=test。

我不是一个rails专家，所以我不知道是否应该在迁移开发数据库时自动迁移测试数据库，但是这会迁移它，并且它解决了类似的问题。

注意：我的操作系统是Windows 8.1

是的，问题出在Windows上。当您阅读在railsinstaller目录中找到的fileutils.rb的代码时。它想要取消链接，并且要给予权限700（在unix/linux中），但不能在Windows中。所以不会工作。

以下是fileutil.rb文件的代码片段。

def remove_file 
    platform_support { 
    File.unlink path 
    } 
end 

def platform_support 
    return yield unless fu_windows? 
    first_time_p = true 
    begin 
    yield 
    rescue Errno::ENOENT 
    raise 
    rescue => err 
    if first_time_p 
     first_time_p = false 
     begin 
     File.chmod 0700, path() # Windows does not have symlink 
     retry 
     rescue SystemCallError 
     end 
    end 
    raise err 
    end 
end

我注意到这种情况，如果我有一个终端打开运行rails服务器和另一个终端工作。我的工作终端是什么给我这个问题，当我尝试删除或重置数据库。我关闭服务器并再次尝试，它工作正常。
