我正在尝试运行this project。当我在db和root中启动docker-compose时，出现以下错误：
backend_1 | File "/usr/local/lib/python3.8/site-packages/django/db/backends/base/base.py", line 220, in ensure_connection
backend_1 | self.connect()

从postgres docker我获得以下信息：
postgres_1 | 2020-03-21 09:49:56.090 UTC [1] LOG: listening on IPv4 address "0.0.0.0", port 5432
postgres_1 | 2020-03-21 09:49:56.090 UTC [1] LOG: listening on IPv6 address "::", port 5432
所以，看来我的postgres运行在0.0.0.0上，后端正在尝试访问192.168.1.107。
我尝试将DB_HOST=192.168.1.107中的DB_HOST=localhost更改为.env.dev，但不知怎么也不起作用。
我如何使其工作？
