Question

在安装django_extensions后尝试启动shell_plus时出现以下错误。以下是我遵循的步骤使用

安装了1个django_extensions

pip install django_extensions

2 - 为已安装的应用添加django_extensions

然后我收到以下错误

$ ./manage.py shell_plus           
Traceback (most recent call last):
  File "./manage.py", line 15, in <module>
    execute_from_command_line(sys.argv)

有关可能出现的问题的任何建议？

Answer 1

Python 3.5附带了自己的输入模块版本。最有可能发生的事情是你的需求中指定了另一个输入模块（不包含Type类的模块），并且它被django_extensions而不是本机Python获取。检查已安装的模块，或尝试运行：

pip uninstall typing

用Django安装的shell_plus给出错误 - ImportError：无法导入名称＆＃39;类型
