The error env.missing

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/env/_check.py:

  • what happened: {…} {…}, pinned by {…}, is not installed

  • what to do: rebuild the environment from the pinned requirements ('mime modal' writes a script that does)

• in mime/errors/_missing.py:

  • what happened: {…} is not installed, and {…} requires it (MIME could not import {…})

  • what to do: install it with MIME's requirements: '{…}'; or the package alone: pip install {…}
