Comment:
```
Looking for .cabal or package.yaml files to use to init the project.
Using cabal packages:
- ./

Selected resolver: lts-12.26
Initialising configuration using resolver: lts-12.26
Total number of user packages considered: 1
Overwriting existing configuration file: stack.yaml
All done.
WARNING: Ignoring Cabal's bounds on containers (>=0.4.2.1 && <0.6); using containers-0.6.0.1.
Reason: trusting snapshot over cabal file dependency information.

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for language-python-0.5.6:
    containers-0.6.0.1 from stack configuration does not match ==0.5.*  (latest matching version
                       is 0.5.11.0)
needed since language-python is a build target.

Some different approaches to resolving this:

  * Set 'allow-newer: true'
    in /builddir/language-python-0.5.6/.stack/config.yaml to ignore all version constraints and build anyway.

  * Recommended action: try adding the following to your extra-deps
    in /builddir/language-python-0.5.6/stack.yaml:

- containers-0.5.11.0@sha256:28ad7337057442f75bc689315ab4ec7bdf5e6b2c39668f306672cecd82c02798,16685
