Stack: Starting a new project fails to build

[gregberns]

When following the directions in (start-your-new-project)[https://docs.haskellstack.org/en/stable/README/#start-your-new-project] there are some errors I cannot decipher and can't find any helpful resolutions.

During stack build the following error occurs, but I don't know what it means:

Error parsing targets: The specified targets matched no packages.

Any help getting past this would be much appreciated. I can re-open on stack overflow if that would be better.

I've run stack update and stack upgrade, and should be on the latest everything.

Am I missing something??

cd to project directory

cd state-machine-testing/

Run stack setup

$ stack setup
stack will use a sandboxed GHC it installed
For more information on paths, see 'stack path' and 'stack exec env'
To use this GHC and packages outside of a project, consider using:
stack ghc, stack ghci, stack runghc, or stack exec

Running stack build shows the following error

$ stack build
Error parsing targets: The specified targets matched no packages.
Perhaps you need to run 'stack init'?

Running stack exec

$ stack exec state-machine-testing-exe
Executable named state-machine-testing-exe not found on path: .....<PATH INFO>

Stack version

$ stack --version
Version 1.9.3, Git revision 40cf7b37526b86d1676da82167ea8758a854953b (6211 commits) x86_64 hpack-0.31.1

Can you post the output of

stack new state-machine-testing --resolver=nightly

[gregberns]

@mihaimaruseac

I just ran stack new again without the nightly flag, and instead of the
No updates to your package index were found message, I got Downloading snapshot with a couple other messages.

I then tried the same with a new project name and included the nightly flag, then ran stack setup and its now downloading GHC 8.6.3.

So it looks like something changed, or running nightly helped.

EDIT: Once the new GHC was installed, I ran setup and build on both the non-nightly and nightly and they BOTH ran and built correctly.

Here's the output of the two stack new tests.

So it seems that now you can build the new projects. Can you verify that this is the case?

I think you were in an inconsistent snapshot state before and a package has not been updated to the version in the snapshot. By the time you ran the new commands this got self-fixed.

[gregberns]

Yes, I can now build new projects consistently (3 successful attempts).

Thank you very much for the help.

I'm getting this same issue when trying to build a dockerfile.

Dockerfile is:

```FROM ubuntu:bionic

Hi @AndyWatt83. This looks like a separate issue, would you like to open a new issue please? Posting the error message too and any other details that might help us in debugging this fast? Thanks
