Warning: Unable to save CompilerPaths cache: #6330

@kant2002, thanks for reporting. It looks to me like you are using GHCup to customise Stack's installation of GHC (https://docs.haskellstack.org/en/stable/yaml_configuration/#ghc-installation-customisation), because of the line: So, this may be a GHCup bug rather than a Stack one. The basic problem seems to me to be that GHCup is promising to provide GHC 9.0.2 and is failing to do so. A work around might be to allow Stack to manage its GHC requirments. That would involve deleting the |

I forgot to mention that stack build/stack run seems tot be working fine. Also this EXE file is present and is executed seems to be correctly. |

Ok, so GHCup must be supplying GHC 9.0.2 (contrary to what I assumed above). |

Stack throws that warning in mres <-
case eres of
Left e -> do

Just cp -> cp <$ logDebug "Loaded compiler information from cache"
Nothing -> do

@kant2002, one way to test my theory is that in the #!/bin/sh

Ooh. That was lightning fast. I go to sleep and on next day before I at home this is fixed. Super cool! |

Steps to reproduce
Not sure what steps:

I would like that

After running
stack path --stack-rootwhen add
