odoo 10 blog

求助大神 我装的是odoo10社区版，安官网的教程在线安装的。打开blog报unsupported operand type(s) for -: 'datetime.datetime' and 'datetime.date' Traceback

最好能给出完整的server log，你也可以在runbot里面测试下看看是不是有同样错误。

这是报错的详细信息

I solved on CentOS Linux release 7.3.1611 by upgrading babel.
First I've upgraded pip and then babel:
pip install --upgrade pip
pip install --upgrade babel
Restart odoo server and Blog app works!
你升级一下babel。
pip install --upgrade pip
pip install --upgrade babel
