SyntaxError：在Django上运行syncdb时语法无效

Question

I'm trying to install a django-cms variant (wagtail) and get everything working up until I am doing the './manage.py syncdb'. At that point I get the traceback as follows:

Traceback (most recent call last):

SyntaxError: invalid syntax

Seems like the for loop syntax is okay...any ideas? Or was there a massive change in syntax between python 2.6.6 and python27?

I am running PYTHON 2.6.6 and DJANGO 1.6.1 running on RHEL 6.4 (2.6.32-358.el6.x86_64), postgres 8.4.18

Any ideas or thoughts would be greatly appreciated

Answer 1

dictionary comprehensions were added in Python 2.7 . You're running 2.6. So you need to change this line:

indexed_fields = {field: dict(type="string") for field in indexed_fields}

Into this:

indexed_fields = dict((field, dict(type="string")) for field in indexed_fields)
