GAE: Another transaction by user acct is already in progress
GAE经常遇到这样的状况:Another transaction by user acct is already in progress for this app and major version. That user can undo the transaction with appcfg.py’s “rollback” command.
解决方法:
CD进入APP文件夹,命令”appcfg.py -verbose —no_cookies —email=email@gmail.com —passin rollback ./”
