Migrating to Python 2.7

[Kim Jae]

I found an interesting tutorial here and followed it.


http://eixerits.wordpress.com/2013/07/20/python-2-7-migration-demystified/

however, I have encountered some problems.

I tried to deploy the my app and I got an error message:

2013-08-29 21:29:28 Running command: “['C:\\Python27\\pythonw.exe', '-u', 'C:\\Program Files\\Google\\google_appengine\\appcfg.py', '--no_cookies', u'--email=bus...@gmail.com', '--passin', 'update', u'C:\\Users\\xplore\\Documents\\shitty shit\\cs']”
09:29 PM Host: appengine.google.com
Error parsing yaml file:
while scanning a simple key
in “C:\Users\xplore\Documents\shitty shit\cs\app.yaml”, line 10, column 1
could not found expected ‘:’
in “C:\Users\xplore\Documents\shitty shit\cs\app.yaml”, line 11, column 1
2013-08-29 21:29:44 (Process exited with code 1)

You can close this window now.

I tried to check my .yaml file and this is what it says: 

application: yourapp

version: 2
runtime: python27
api_version: 1
threadsafe:true
handlers:
- url: /images
static_dir: images
- url: /
script: main.app
login: admin
- url: /getvalue
script: main.app
login: optional
- url: /setvalue
script: main.app
login: optional
- url: /sendemail
script: main.app
login: optional
builtins:
- datastore_admin: on

I have no idea what went wrong with the code. I'm kinda new to Python so it's impossible for me to figure out what I need to change in lines 10 and 11 based on the yaml file. Please enlighten me on the possible solutions.

Your response is appreciated.

Are you indenting your YAML lines correctly? Based on the file you pasted, I don't see any indentation.

YAML is similar to Python in that it requires developers to indent lists/properties. Use spaces when indenting, not tabs. See http://yaml.org/spec/1.2/2009-07-21/spec.html#id2576668

Hello! thank you for your response. I don't think spacing is the problem because I was able to successfully deploy the previous yaml file. I just added a few words and changed some.  attached is the original notepad for your reference.

The errors you reported are pretty specific. It's a problem with you app.yaml

I would look at the line immediately preceeding line 10.

OK, I think I have it. Add a space between threadsafe: and true so it looks like this: threadsafe: true (space is after the colon ":" )

I tested your app.yaml file on a PHP application I had, and it worked when I added a space (and edited the script names, of course!). Just to explain what happened, here is a picture of your app.yaml that I annotated: http://imgur.com/Y79j1XX There are extra blank lines, so the 10th and 11th lines are actually the 6th line of text.

For future reference, see this page of the YAML spec: http://www.yaml.org/spec/1.2/spec.html#id2759963

TLDR: Keys and values must be separated by a colon and space (i.e. Key: Value)

Thanks for the info! would you mind taking a look at the revised yaml file I made? I tried to deploy it but am still getting Process exited with code 1 error. attached is the file for your reference.

Great, I see you removed all the blank lines. It looks much neater now!

Also, did the error message change? Does it cite a different line number where it encountered the error? If not, try this: remove all the handler statements except for the root handler (url: /), and try re-uploading the application. If it succeeds, then add in another handler statement, then re-upload. Rinse and repeat until you hit the handler that's causing the error.

Thank you for your suggestion! I tried it and it works! :)
