--- Comment #13 from vialav <d...@bk.ru> --- UPDATE: The cause of errors has been identified and half-successfully dealt with: https://github.com/ipython/ipython/issues/11485# IPython crashes at launch (closed, no action) https://github.com/powerline/powerline/issues/1953# powerline-status crashes with ipython>=7.0.0 https://github.com/powerline/powerline/pull/1997# Fix #1953 (pending merge) ** First, I'm using `powerline`, which was (and still is) the cause of the reported issue **, so here comes the starting point of yet to be updated RTD: https://powerline.readthedocs.io/en/master/usage/other.html#ipython-prompt #!~/.ipython/profile_default/ipython_config.py - For IPython>=5.0 (and << 7.0) follow the RTD - For IPython3>=7.0 after merging locally above referenced the pull `since_7` has to be used. OBSERVED RESULT: as in #1953 (`ipython` with `--single-prompt` crashes, `ipython3` does not) Resulting `ipython_config.py`, pass for `ipython` (python[2] under Sage): ``` python import sys if sys.version_info >= (3, 0): from powerline.bindings.ipython.since_7 import PowerlinePrompts c = get_config() c.TerminalInteractiveShell.simple_prompt = False c.TerminalInteractiveShell.prompts_class = PowerlinePrompts else: pass ``` ** Cantor is able to log in into Sage (python2) with `exec sage -i --simple-prompt` ! **: ShortcutOverride 16777220 QFlags<Qt::KeyboardModifiers>(ShiftModifier) login found version: ("8.6", "8", "6") wsStatusChange 1 evaluating: "1+2" wsStatusChange 0 out: "┌────────────────────────────────────────────────────────────────────┐\r\n│ SageMath version 8.6, Release Date: 2019-01-15 │\r\n│ Using Python 2.7.15.
