>>> import MySQLdb

命令行上的一切顺利，但我仍然在appengine日志中得到以下内容

Answer 1

您是否尝试使用CloudSQL？如果没有，不要担心rdbms API警告，该行是无害的。 PIL警告也是如此。

您不应该收到有关无法读取数据存储文件的警告。它可能是文件权限的问题，或者文件可能以某种方式被破坏。如果他们没有必要的数据，请尝试清除数据存储文件并再次尝试。

Answer 2

请将此行import MySQLdb添加到dev_appserver.py文件中，如果您尚未这样做的话。

Mountain Lion上没有Google AppEngine'rdbms API'
