spacemacs C-c C-p 运行python 之后报错的

巨大的建筑，总是由一木一石叠起来的，我们何妨做做这一木一石呢？我时常做些零碎事，就是为此。
这是对的，但是我没有说过这句话！ —— 鲁迅

在spacemacs中用 M-x run-python 之后，报错：

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

如图：

查看一下 python-shell-completion-native-disabled-interpreters 的帮助

C-h v python-shell-completion-native-disabled-interpreters

如下：

python-shell-completion-native-disabled-interpreters is a variable defined in ‘python.el’.
Its value is ("pypy" "ipython")

Documentation:
List of disabled interpreters.
When a match is found, native completion is disabled.

You can customize this variable.

This variable was introduced, or its default value was changed, in
version 25.1 of Emacs.

[back]

写的比较清楚，或者将 python 加入到list里面，或者安装一个ipython,我选择了后者：

pip3 install ipython

再重新运行，一切正常了！，直接 C-c C-c 运行.如图：
