One surprisingly effective option is this:

import blargle.spam # Solution: pip install blarg

Comes out looking like this:

Traceback (most recent call last):
  File "useblarg.py", line 1, in <module>
    import blargle.spam # Solution: pip install blarg
ModuleNotFoundError: No module named 'blargle'

(in older Pythons, that says "ImportError" rather than the more
specific subclass, but same diff)

You can put whatever you like onto that command line.
