问题描述

当我尝试运行bundle exec rake test:models时，我正在使用railstutorial的草稿版本，但出现以下错误消息： 

rake aborted!
Errno::EACCES: Permission denied - C:/Users/Alex/Desktop/Workspace/Rails/sample_
app/db/test.sqlite3

Tasks: TOP => test:run => test:units
(See full trace by running task with --trace)

使用--trace：

我尝试检查db文件夹上的权限，还尝试重新启动所有内容。 我在Windows上使用的是Rails版本4.2.0beta1。 当我制作“用户”模型时，问题开始了。 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已损坏。 如果我将/config/database.yml测试更改为/db/development.sqlite，则测试正常。

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，这似乎已经解决了问题。

在运行rake db:migrate RAILS_ENV=test之前，运行rake db:migrate RAILS_ENV=test 。

我不是Rails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，但这将对其进行迁移，它解决了我的类似问题。

注意：我的操作系统是Windows 8.1

是的，问题出在Windows。 当您阅读railsinstaller目录中的fileutils.rb代码时。 它想取消链接并要授予权限700（在unix / linux中可以找到），但不能在Windows中。 因此将无法正常工作。

这是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

我注意到如果我打开了一个运行Rails服务器的终端而另一个要运行的终端，则会发生这种情况。 我的工作终端是在尝试删除或重置数据库时出现问题的原因。 我关闭服务器并再次尝试，它工作正常。
