Getting "Too many errors from stdin"

Hi,
I'm having trouble with a variety of scenarios where I'm getting the message "Too many errors from stdin" presumably from nano.
The issue occurs for instance when using the man command or when issuing the help function from Python but also happened in other cases that don't come up to my mind right now.

Example:

$ man ping
Too many errors from stdin
Buffer written to nano.save.7
man: command exited with status 1: sed -e '/^[[:space:]]*$/{ N; /^[[:space:]]*\n[[:space:]]*$/D; }' | (cd <fd 3> && LESS=-ix8RmPm Manual page ping(8) ?ltline %lt?L/%L.:byte %bB?s/%s..?e (END):?pB %pB\%.. (press h for help or q to quit)$PM Manual page ping(8) ?ltline %lt?L/%L.:byte %bB?s/%s..?e (END):?pB %pB\%.. (press h for help or q to quit)$-R MAN_PN=ping(8) nano)


$ python
Python 3.6.4 (default, Jan  5 2018, 02:35:40) 
[GCC 7.2.1 20171224] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> help(dict)
Too many errors from stdin
Buffer written to nano.save.6

>>> 

It appears to happen on many interactive texts from the shell (that presumably make use of nano?).
Does not occur with programs like less or more.
The files produced because of the errors (e.g. nano.save.6) do actually contain the expected text (help(dict) in the latter example).

P.S. This is my first post on the Arch Forum, please let me know if I'm doing anything wrong.

Give us you `env` output.

Makes sense. Does your issue disappear if you remove this crap?

Re: Getting "Too many errors from stdin"

While I agree that oh-my-zsh is trouble, that is not the cause here.  The cause quite clearly is that you are setting nano as your PAGER.  Nano is *not* a pager.

This is easy to replicate by sending any short file or text stream to nano's stdin.

EDIT: It might be possible to use nano as a pager with PAGER='nano -' but this still seems like a bad idea.  But just nano itself will definitely not work.
