On Emacs 25.2 and Python 3.5 on an Centos-like Oracle Linux I have the issue that invoking a python shell gives me no completion. To reproduce, start
$ emacs -Q --eval '(setq python-shell-interpreter "python3")'
This produces the warning
Warning (python): Your ‘python-shell-interpreter’ doesn’t seem to support readline, yet ‘python-shell-completion-native’ was t and "python3" is not part of the ‘python-shell-completion-native-disabled-interpreters’ list. Native completions have been disabled locally.
It is the same problem as Your ‘python-shell-interpreter’ doesn’t seem to support readline, but:
1) I am already on Emacs version 25.2, so the fixfrom one answer does not help (because 25.2 contains the proposed fix).
2) I am on bash 4.1 and have no ~/.inputrc file, so the fix from the other answer doesn't help either.
How can I fix this?
On my MacOS machine the initialisation works correctly. However on MacOS I use Emacs 25.3. Therefore I installed 25.3 (from source ) on the Oracle Linux system, too - the Python completion still fails, because of same above mentioned issue!
