尝试在代码更改时使用看门狗自动重启 docker 容器中的 celery worker/beat，并得到错误：
# watchmedo auto-restart -d . -R -- celery -A main_app_name beat -l info
Traceback (most recent call last):

从 requirements.txt 安装的所有依赖项：
***
pyyaml~=6.0
watchdog~=2.1.6
auto-restart~=2.2

在容器中搜索“auro-restart”文件时，得到：
# find / -type f -name '*auto*restart*'
/root/.cache/pip/wheels/40/11/c1/9e570f5aac7910cf701243cda8b5fc58e56b329a3d73b4840b/auto_restart-2.2-py3-none-any.whl

有人知道这个问题的原因吗？
