SyntaxError：在Django上運行syncdb時無效的語法

我試圖安裝一個django-cms變體（w）），並讓所有的東西都運行起來，直到我做'./manage.py syncdb'。在那一點，我得到的回溯如下：SyntaxError：在Django上運行syncdb時無效的語法

似乎for循環語法是好的...任何想法？或者是Python 2.6.6和python27之間的語法發生了巨大的變化？

我正在PYTHON 2.6.6和1.6.1 DJANGO在RHEL 6.4（2.6.32-358.el6.x86_64）運行，Postgres的8.4.18

任何意見或想法，將不勝感激

dictionary comprehensions were added in Python 2.7。你正在運行2.6。所以，你需要改變這一行：

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

進入這個：

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

感謝您的回覆迅速...我想它有一些東西做的版本。不幸的是，RHEL僅附帶Python 2.6（除了新的軟件集合），但我對語法進行了更改，並且所有工作都完美無瑕。請注意，在prod中部署Python27。 – djfidelio

是的，我出於完全相同的原因在2.6環境中停留在我的環境中 – mhlester
