Fixed by using v1.29.2. latest version doesn't work

Error looks to come from the .env parser; https://github.com/compose-spec/compose-go/blob/7d49c99fcfd2f99332d95e3b69c0c8d07fa13422/dotenv/parser.go#L119

• Do you have a .env file present?
• What does command -v docker-compose show? (Is it possible it's an alias or script?)

I tried reproducing this issue on an Ubuntu machine, but didn't get the same issue (without a .env file);

So I run docker-compose without any additional arguments and get this error:
unexpected character "-" in variable name near "docker-compose up -d --build"

[ndeloof]

This is probably fixed by compose-spec/compose-go#336
Anyway, we should offer a better error to the user, with some details on the file we failed to parse, so keeping this issue open for this purpose

[ayzeenm]

Amazing! thank you @ndeloof , it actually got fixed
