使用Django框架创建完models类的之后，用python manage.py migrate命令来生成数据库表的时候出错
Operations to perform: Apply all migrations: SMS, admin, auth, contenttypes, sessions Running migrations: Running migrations: Traceback (most recent call last): File "manage.py", line 22, in <module> execute_from_command_line(sys.argv) File "C:\python35\lib\site-packages\django\core\management\__init__.py", line 364, in execute_from_command_line utility.execute() File "C:\python35\lib\site-packages\django\core\management\__init__.py", line 356, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "C:\python35\lib\site-packages\django\core\management\base.py", line 283, in run_from_argv self.execute(*args, **cmd_options) self.execute(*args, **cmd_options) File "C:\python35\lib\site-packages\django\core\management\base.py", line 330, in execute output = self.handle(*args, **options) File "C:\python35\lib\site-packages\django\core\management\commands\migrate.py", line 177, in handle self.stdout.write(self.style.MIGRATE_HEADING("Running migrations:")) File "C:\python35\lib\site-packages\django\core\management\base.py", line 110, in write self._out.write(force_str(style_func(msg))) OSError: raw write() returned invalid length 42 (should have been between 0 and 21)
与win10系统、版本有关系
可能是unicode字符的返回值问题
可以使用pip install win_unicode_console安装win_unicode_console，在代码文件中添加以下两行代码解决：
import win_unicode_console win_unicode_console.enable()
【Django错误】OSError: raw write() returned invalid length 14 (should have been between 0 and 7)
