The error load.derived-hash

environment: something the run needs is missing or different where it runs (a package, a file, a device, the network): the error names what to install, fetch or attach.

Where MIME gives it, with what its message says happened and what its action says to do ({…} is filled in from the experiment):

• in mime/saved/_folder.py:

  • what happened: in the environment the lock was written in, the rebuilt graph differs from the saved one: {…}

  • what to do: an entry builds something other than what its version built: report it to the package that registers it; 'mime registry' lists each entry's version

Reading an error and reaching its full traceback: reading an error. Every code: the index.
