Question

我正在执行railstutorial的草稿版本，当我尝试运行bundle exec rake test:models时收到此错误消息：

我已经尝试检查我的db文件夹的权限，并尝试重新启动所有内容。我在Windows上使用rails版本4.2.0beta1。当我制作“用户”模型时，问题就出现了。我尝试回滚并再次迁移。

编辑：似乎我的测试数据库在某种程度上被破坏了。如果我将/config/database.yml测试更改为/db/development.sqlite，则测试可以正常工作。

Answer 1

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

Answer 2

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

我不是专家，所以我不知道在迁移开发数据库时是否应该自动迁移测试数据库，但这会迁移它，并解决了我类似的问题。

注意：我的操作系统是Windows 8.1

Answer 3

是的，问题出在Windows上。当您读取railsinstaller目录中找到的fileutils.rb的代码时。它希望取消链接并希望授予权限700（在unix / linux中找到）但不在Windows中。所以不行。

以下是fileutil.rb文件的片段。

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

Answer 4

我注意到如果我有一个终端打开运行rails服务器而另一个终端要工作，就会发生这种情况。我的工作终端是我尝试删除或重置数据库时给我的问题。我关闭服务器并再次尝试，它工作正常。

bundle exec rake test：模型抛出Errno :: EACCES：权限被拒绝
