The error env.unpinned

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: {…} {…} is installed and nothing pins it

  • what to do: uninstall it ('pip uninstall {…}'), or pin it in the lab's requirements (--lab <file>); {…}

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