Default readline version installed when creating environment doesn't work with URxvt

[tomeaton17]

I am using Ubuntu 17.04 with URxvt as my terminal emulator. When I create a new environment with conda create -n myenv python=3.6 there is no errors with this command. I then try to use the python prompt I cannot use backspace or arrow keys. When I do use these keys, it just adds blank characters to the prompt. This means that the keyboard control characters are not being interpreted correctly.

To fix this I must go into envs/myenv/lib and delete all libreadline files. I then install readline with pip install readline. The version of readline is 6.2.4.1.

Please can you fix the readline that is installed by default so that it works with URxvt.

I have the same issue (Ubuntu 16.04, urxvt).

It can be also solved by downgrading to readline 6.2 using conda:

conda install readline=6.2

The described issues don't seem to be readline-related but instead terminfo-related. See my comment at #8271 for how I fixed it without downgrading.

I suggest closing this issue or #8271 as they deal with the same issue.
