遵循python教程时出错

Question

我试图在任何地方的python教程中同步数据库。我删除了所有内容，并多次重新启动本教程，当我这样做时：

python ./manage.py syncdb

03:23 ~ $ cd mysite
03:23 ~/mysite $ ls
__init__.py __init__.pyc manage.py media settings.py settings.pyc static testdb urls.py urls.pyc
03:23 ~/mysite $ python ./manage.py syncdb
Traceback (most recent call last):
File "./manage.py", line 14, in <module>

Answer 1

有几件事可能导致这个问题：

1. 如果您使用的是settings.py中sqlite文件的相对路径，请尝试将其更改为绝对路径： 使用~/project/mydata.db代替/home/user/project/mydata.db。
2. 如果没有正确设置权限，则可能会出现写入文件的问题。试试这个： sudo python manage.py syncdb 如果该方法有效，则需要解决一个简单的权限错误。
3. 项目的目录文件名与数据库文件之间可能存在名称冲突。如果settings.py中的数据库名称与项目名称相同，请尝试在文件名中添加.db： 也就是。 项目名称：test 数据库名test.db
