学习python编程 从入门到实践第18章时,创建数据库失败
python manage.py migrate 执行失败,报错:
'%s=%s' % (k, v) for k, v in params.items(), SyntaxError: Generator expression must be parenthesized
解决方法:
找到widgets.py文件,使用vim编辑器打开
修改
'%s=%s' % (k, v) for k, v in params.items(),
为:
'%s=%s' % (k, v) for k, v in params.items()
然后再次执行 python manage.py migrate 即成功
