How can I build a project on the stack?

Question

Haskell

After the stack build command , I get:

Please tell me, who knows how to deal with this?

Answer 1

The presence of a README does not affect the build.
Such errors occur when the build was interrupted via Ctrl+C or was simultaneously launched from several places (terminal + IDE for example).
It is treated stack cleanby deleting .stack-workand starting again.
If it's really bad, then delete everything and unload the project code again.
Plus, Windows still has its own problems with the linker. Usually treated by updating to the latest GHC.
PS: A question from three years ago, since then a little protection against this has been added to the stack and it happens less often.
