系统：macOS Mojave 10.14.6
Python3：Python 3.7.4
我的 emacs 配置（根据 https://github.com/hlissner/doom-emacs/issues/212 ）；
(setq python-shell-interpreter "/usr/local/bin/python3" flycheck-python-pycompile-executable "/usr/local/bin/python3")
尝试在 emacs doom 中使用 run-python。拥有：
Python 3.7.4 (v3.7.4:e09359112e, Jul 8 2019, 14:54:52)
[Clang 6.0 (clang-600.0.57)] on darwin

>>> python.el: native completion setup failed, <class 'ModuleNotFoundError'>: No module named 'readline'
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.
import readline 在终端的 python3 中完美运行。
默认的 python 2.7.10 也不起作用（没有我的 emacs 配置）。

如何让emacs doom正确运行python3？
尝试将其设置为python3
(setq python-shell-interpreter "python3"
python-shell-interpreter-args "-i")
你可以在init.el
设置它
