Docker compose 返回的必须是一个映射。 YML看起来文件

Question

遇到映射错误并且无法弄清楚错误是什么 YML 似乎是有效的，并且 .env 文件在与撰写相同的目录中设置了正确的变量。我尝试将 env_file 行压缩为一行，但这不起作用。

services.mixpost.environment must be a mapping

这是完整的 YML，它是直接从供应商网站复制的，以尽量减少错误。我已经通过 YML 验证器传递了它，并尝试清除空格，但没有成功。

Answer 1

错误是您指定了空（因此无映射错误）

environment

部分。

您只需将其删除并重试即可。

让我知道它是否有效。
