First I know, there is also same problem in Forum. But I am totally novice at linux. So I need an answer for noobs.
I get this error when I try to turn on my laptop. It happened after installing Anaconda for Python.
I only know my desktop version is Kde. Not Gnome.
I only know typing ‘killalll’, ‘su’ and ‘mkdir’ and ‘cd’, ‘ls’.
Well, apparently the Anaconda installer breaks the system.
Open the file ~/.bashrc in a text editor and remove the line that starts with “export PATH=…” (probably somewhere at the end).
If in doubt, post the content of the file, and I’ll tell you what line to remove.
Thank you very much for your attention.
The error that I mentioned is in a window. There is only a OK button but it does not work.
So it is stucks there and I press Ctrl + Alt + F1. A terminal opens. It says so:
Welcome to openSUSE Leap 42.1 - Kernel 4.1.34-33-default (tty1)
Hint: Num Lock off
linux-0fhu login:
I press enter, I get same message. Then I type sudo, it asks me Password. I type it. Unfortunately it says Login Incorrect. I thought it is because of my keyboard (not English) But it is irrelevant. I see the chararcters before Password screen.
Therefore I am stuck.
Yes, Plasma won’t start until you make that change.
Select IceWM on the login screen instead.
If you have Auto-Login enabled, press Ctrl+Alt+Backspace twice to get back to the login screen.

You need to enter your username and then your password.
And you won’t need sudo at all for this anyway.
Thank you again. But when I login, there is only 3 options.
1 . openSUSE Leap 42.1 ( this path goes and ends where I have been stuck at)
2. Advanced options for openSUSE Leap 42.1 (Two sub-choices: opensuse leap 42.1 with linux 4.1.34.33- default and opensue leap 42.1 with linux 4.1.41 30 default)
3. Start bootloadet from a read-only snapshot (threre are lots of sub categories. Something sth… post, yast sw etc.)
I do not know how to select sth. 
Thanks again.
That’s not the login, that’s the boot menu.
Just boot normally (openSUSE Leap 42.1).
I just assume you have Auto-Login turned on, otherwise you would know about the login screen… 
So, just wait until you get that error dialog, and then press Ctrl+Alt+Backspace twice and you should get back to the login screen, as I wrote.
There’s a chooser there that says “Plasma5”, click on it and choose “IceWM”, then enter your password.
When in, you will have quite a spartanic desktop, but you should be able to start all installed applications via the start button in the bottom left corner (not unlike Plasma), the installed apps are in the “SUSE” submenu.
Choose a text editor there (Utilities->Editor->KWrite e.g.), open the file ~/.bashrc and modify it accordingly, then save it.
Plasma5 should start again afterwards.
Or click on the “terminal” button in the bar at the bottom, and type commands in.
Alternatively you can switch to text mode via Ctrl+Alt+F1, but then you have to enter your user name first (and press Enter), then your password.
And it would probably be even more difficult to explain how to edit that file in text mode…
Though actually you can also just remove or rename ~/.bashrc, if you feel lost with modifying it.
One of these commands should do:
mv ~/.bashrc ~/.bashrc.bak
(this will rename it, so it isn’t used)
or
rm ~/.bashrc
(this will delete it completely)
In the end you could also use dolphin (inside IceWM) to do that btw.
Unfortunately I formatted and reinstalled. But thank you for your help.
You’re welcome.
But for your information, I did submit a change to our Plasma5 packages that should prevent that problem with anaconda months ago, in time for the 42.2 release…

Sorry for not mentioning it here, but there were 3 threads about the same problem back then and I didn’t remember/find all of them.
