bundle exec rake test：模型抛出Errno :: EACCES：权限被拒绝
我正在做railsstutorial的草稿版本，当我尝试运行bundle exec rake test:models我收到此错误消息：

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。 我尝试回滚并再次向上迁移。
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，则测试工作正常。
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，这似乎解决了这个问题。
在运行rake db:migrate RAILS_ENV=test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，并解决了我的类似问题。
注意：我的操作系统是Windows 8.1
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。
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
我注意到如果我有一个终端打开运行rails服务器和另一个终端工作，就会发生这种情况。 我的工作终端是在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。
