Google App Engine throws this InvalidURL("nonnumeric port: '%s'" % host[i+1:]) exception when I try to deploy. How do I fix it?

Question

When I click the Deploy button for my project, it gives me the following error: File "C:\Python27\lib\httplib.py", line 721, in _set_hostport raise InvalidURL("nonnumeric port: '%s'" % host[i+1:]) httplib.InvalidURL: nonnumeric port: 'port'.

I've successfully deployed this project before, so I tried reverting the files so that I would have the same files when it worked properly. No dice, it seems. That was just a jab in the dark, though -- the full trace shows this starting in Google App Engine's files, not mine.

Anyone know how I can deploy my project?

You can close this window now.

Answer 1

I've resolved this by completely uninstalling and reinstalling both Python 2.7 and GAE. This complete wipe should include the deletion of any environment variables that have been set since your usage of GAE.

In my case, I think it was particularly the creation of environment proxy variables. A complete wipe of Python and GAE resolved this.

I'll preface this by saying I'm not familiar with the GUI, so feel free to completely disregard :).

The error seems to indicate that you are trying to specify a particular port for deployment, and furthermore, the value of that setting is the word 'port'. When using the commnand line with the dev server, port is an argument you can use to specify a particular port to use; my best guess is that this keyword parameter is still defined (as port) when you are trying to deploy. Is there a section where you can specify command-line flags? Is it possible that port is defined there when deploying?
