[SOLVED] Getting an "invalid syntax" error from __init_

Getting an "invalid syntax" error from __init__.py

I'm following this example for using Flask-JWT:

And I get this error when I start uwsgi:


Traceback (most recent call last):
  File "./wsgi.py", line 1, in 
    from main import app as application
  File "./main.py", line 5, in 
    from auth import api_auth
  File "./auth.py", line 3, in 
    from flask_jwt import JWT
  File "/opt/mist_base/env/lib/python2.6/site-packages/flask_jwt/__init__.py", line 83
    for claim in verify_claims
      ^
SyntaxError: invalid syntax

I've been only using Python v2.6.6 (for Centos 6.x per customer specification) for only a week so I'm still very green at it. As a result, earlier today I discovered I had multiple variations of JWT-something in my virtualenv so I removed all instances and only reinstalled Flask-JWT. I had thought the issue was library conflicts (and it may have been earlier), but I'm still getting this error and other people have used it with no issues. Am I doing something wrong or is this library simply not designed to be used with Python v2.6.x?

[UPDATE] I've gone ahead and compiled v2.7.12 from source in CentOS 6 and so far it works nicely for my needs. I found these directions:

and was able to install in an alternate directory.

Solution

This library just doesn't work on Python 2.6. The source code relies on features like dict comprehensions that only exist in 2.7 and up.
