[TerminalIPythonApp] WARNING | Unrecognized alias: 'im', it will have no effect.

I’m used to write ipython -im <modulename> to do interactive Python hacking. However, on one installation it doesn’t work.

Working machine:

(env) brahe$ ipython -im os
Python 3.8.2 (default, Jul 16 2020, 14:00:26) 
Type 'copyright', 'credits' or 'license' for more information

Non-working machine:

(env) arvid-m12$ ipython -im os

Both machines have the same versions, only from pip and no system installation:

$ dpkg --list | grep ipyth
$ pip list | grep ipyth
ipython            7.18.1
ipython-genutils   0.2.0

Using python -i -m os works on both machines.

Looks related to #12711, try to split options:

ipython -i m os

@kalvdans Hey Pal, I finally figured it out, Obtain package compatibility: I got rid of the spyder application with the help of a friend from discord and it was not showing the errors for such stuff on the new M1 macs. I ran this directly from the terminal and this displayed outdated packages that required upgrades. I AM not sure what cause spyder to not be able to recognize such an issue. Maybe a professional can explain further.

I have the same code running fully on the terminal as spyder was experiencing all sorts of glitches, sadly I had to part way with it after using such for so long.

I am really hoping they fix this and as of just now the anaconda navigator is still problematic when downloading such from the website, it’s not running even when deploying the bash file approach still the same. What a shame!!
