Solution for transferring the wrong user name on Google appengine;

Appcfg. py update hooyesapp

Then, the email is wrong with another Google account, and then this idiot's appcfg. PY never gives me the chance to modify it. I log on by default every time. and told me that this account has no permission ....

I cannot change my account;

Now: After you upload appcfg. py, it will write a file named ". appcfg_cookies" in "My document" to record the logon information. Next time you read this file.

So, delete it, and re-enter the email and password in appcfg. py update hooyesapp.
