stack keeps trying to use docker

[turion]

General summary/comments (optional)

Although I try to disable it, stack keeps trying to use docker, which fails. I don't have docker, I don't want docker.

Steps to reproduce

$ stack init
Cannot determine project root directory for Docker sandbox.
$ stack --no-docker init
Cannot determine project root directory for Docker sandbox.
$ stack --no-docker init --verbose
2.1.1.1 x86_64 hpack-0.31.2
2019-07-23 16:26:52.584287: [debug] No project config file found, using defaults.
2019-07-23 16:26:52.589052: [debug] SELECT COUNT(*) FROM "last_performed" WHERE ("action"=?) AND ("timestamp">=?); [PersistInt64 1,PersistUTCTime 2019-07-22 14:26:52.589021511 UTC]
2019-07-23 16:26:52.589441: [error] Cannot determine project root directory for Docker sandbox.

This used to work in version 1.9.

Stack version

$ $ stack --version
2.1.1.1 x86_64 hpack-0.31.2

Method of installation

NixOS unstable

This is actually a red herring, where an error message referencing Docker was used in the Nix support even though Docker isn't actually involved. I believe stack-2.1.3 has fixed this issue, please try it out. See also #4864
