.env 文件被忽略，而不是由`docker-compose`“來源”

Question

案例：我在docker-compose啟動了一個服務。 .env文件中的所有變量.env被忽略，不會被動態替換，如下所示：

PS C:\workarea\jonathan\myProject> docker-compose up -d myService
time="2021-07-23T15:20:50-04:00" level=warning msg="The XXXXX_URL variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The XXXXX_USER variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The XXXXX_PASSWORD variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The YYYY_URL variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The ZZZ_URL variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The XXXXX_URL variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The XXXXX_USER variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The XXXXX_PASSWORD variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The YYYY_URL variable is not set. Defaulting to a blank string."

time="2021-07-23T15:20:50-04:00" level=warning msg="The DDDDD_ROOT_PASSWORD variable is not set. Defaulting to a blank string."

解決方案包括在設置 > 實驗功能中禁用Use Docker Compose V2 ，然后“應用並重新啟動”：

警告：盡管未選中此選項，但 Docker 會在沒有任何用戶操作的情況下重新啟用它。 我在兩台不同的筆記本電腦上多次出現這種情況。
