Possible cause

• In pycharm installation dir./helpers/pydev/_pydev_bundle/pydev_ipython_console.py, $TERM is hard-coded
  • line6: os.environ['TERM'] = 'emacs' #to use proper page_more() for paging
  • This overwrites your $TERM setting if you use iPython console when debugging.
  • If your env doesn't have terminfo for emacs, then it fails.

Workaround

• Add terminfo for emacs

  • I just copied terminfo of dumb-terminal as emacs's terminfo, and it worked. (at least stopped showing messages)
• Or, edit `pycharm installation dir./helpers/pydev/_pydev_bundle/pydev_ipython_console.py``
