Question

使用pip install时我得到了这个。

> pip install cognitive_face
Collecting cognitive_face
  Using cached cognitive_face-1.2.5.tar.gz
Collecting requests (from cognitive_face)
  Using cached requests-2.13.0-py2.py3-none-any.whl

Exception:

我可以在/usr/local/bin和/usr/local/Cellar中的文件夹“python3”中找到文件“python3”和“python3.6”。

此外，我的emacs25无法执行run-python并显示：

Warning (python): Your ‘python-shell-interpreter’ doesn’t seem to support readline, yet ‘python-shell-completion-native’ was t and "python3.6" is not part of the ‘python-shell-completion-native-disabled-interpreters’ list.  Native completions have been disabled locally.

操作系统版本：10.12.3
