emacsのelpyで「Your ‘python-shell-interpreter’ doesn’t seem to support readline・・・」のエラー

emacsのelpyで下記のエラーが発生。

Warning (python): Your ‘python-shell-interpreter’ doesn’t seem to support readline, yet ‘python-shell-completion-native-enable’ was t and "python3" is not part of the ‘python-shell-completion-native-disabled-interpreters’ list. Native completions have been disabled locally.

python3が「python-shell-completion-native-disabled-interpreters」に含まれていないのが原因。

と、いうことで、「M-x elpy-config」で設定。
下の方にある「Option」→「Python」→「python-shell-completion-native-disabled-interpreters」を選択。


「INS」にenterで「python3」を追加。
