我尝试使用本地开发服务器运行我的Google App Engine应用程序 我收到此错误：DatabaseError（＆＃39;数据库磁盘映像格式错误＆＃39;）
我认为数据库文件已损坏。
我跟着这个Stackoverflow post。我尝试删除/mytemporarydir/appengine.myproject.myuser处的临时文件，但我仍然遇到问题。
我也尝试使用选项--storage_path=...运行服务器。它可以运行（使用空数据存储区）但我需要sudo访问权限，当我停止服务器时（进程被阻止），数据库不会被保存。
我想一如既往地运行dev服务器，没有数据库错误，使用默认的storage_path且没有sudo
哪个文件可能已损坏，所以我将其删除？
编辑：我也尝试使用--clear_datastore选项运行服务器。 我使用的是Mac OSX
