【问题描述】：

我在运行 ./manage.py runserver 或 migrate 命令时遇到一些奇怪的错误。我检查了引发异常的文件，但不知道

【问题讨论】：

这是生成的 SQL 中的错误。可以加SQL日志吗？
另外，尝试运行./manage.py sqlmigrate 并查看输出。
DEFAULT_DB_ALIAS 很可能是您的问题。在此处检查语法错误/错字。
我使用 sqlite，如何获取日志？
我可以在不同的主机上运行相同的代码，而且效果很好

【解决方案1】：

问题是用 ucs-2 构建 python，所以用 ucs-4 重建应该可以工作。

Python 2.7.6

wget http://python.org/ftp/python/2.7.6/Python-2.7.6.tar.xz
tar xf Python-2.7.6.tar.xz
cd Python-2.7.6
./configure --prefix=/usr/local --enable-unicode=ucs4 --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
make && make altinstall
