Hi,
I think should be added CircleCI steps to check if nix is built

Local builds also seems to fail:

error: flake 'git+file:///projects/gruntwork/bash-commons' does not provide attribute 'packages.x86_64-linux.defaultPackage.x86_64-linux', 'legacyPackages.x86_64-linux.defaultPackage.x86_64-linux' or 'defaultPackage.x86_64-linux'

@denis256
may you please run

nix build -L --show-trace --verbose --no-fallback

for me it works.

as for CI, i guess until i am part of repo I cannot modify CI (at least CI will not run my files, but master). so I doubt I can help with CI.

[dzmitry-lahoda]

ho, it does not run any check from my PR, so sure not even nix build 264a1e7 .

[dzmitry-lahoda]

build works

[denis256]

$ nix --version
nix (Nix) 2.6.0

$ nix build -L --show-trace --verbose --no-fallback
error: unsupported tarball input attribute 'lastModified'

       … while updating the lock file of flake 'git+file:///projects/gruntwork/bash-commons?ref=dzmitry-lahoda-forks%2fmaster&rev=376247b36cc935ff28a6d5c55b9eaa8835ada7ac'

[dzmitry-lahoda]

@denis256 likely your nix version is tooo old nix (Nix) 2.6.0. Please try 2.17+

CI part: CircleCI can be used on own repos for free https://circleci.com/pricing/

@denis256 i did tried C CI, so it requires some commit and run and complex setup, seems overkill. idea of using PRs is also to run via existing CI, do not require me to do complex setup proc of CI setup with commit of my own pipeline...

not sure I can do anything here.

and not sure how it related at all to have CI gate. nix does not needs ci checks as nix is CI.

Hello,
In the future, how can we ensure that the flake.nix configuration is valid?
I believe the best approach would be to include a NIX build in the existing CircleCI tests. This way, any issues will be detected promptly.
