MacOS，Python：ModuleNotFoundError：没有名为“kiwisolver”的模块

Question

我尝试在 MacOS Sierra 上的 Atom 中导入 kiwisolver，但出现未找到错误：

输入：

import kiwisolver as kiwi

输出：

Traceback (most recent call last):
File "/Users/Kev/Documents/Uvic/Python/PHYS 321B/A6Q5&6_Coupled_Oscillators_Matrix.py", line 3, in <module>
import kiwisolver as kiwi
ModuleNotFoundError: No module named 'kiwisolver'

问题是已经安装好了：

有人遇到过这个问题吗？我该如何解决这个问题？我需要它来运行 Matplotlib。

编辑：我使用的是 Python 3.6。

w134-87-183-190:~ Kev$ python -V
Python 2.7.10

w134-87-183-190:~ Kev$ python --version 
Python 2.7.10

w134-87-183-190:~ Kev$ python3 --version 
Python 3.6.4

在 atom 中，我的 config.cson 中有这个。所有三个路径都给出相同的错误：

runner:
    scopes:
      # python: "/usr/local/bin/python3"
      # python: "/Library/Frameworks/Python.framework/Versions/3.6/Python"
      python: "/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6"

Answer 1

如果您使用的是 Mac，请尝试运行它，因为您可能会遇到一些权限问题：

pip3 install kiwisolver --user

Answer 2

经过 3 个多小时的痛苦，结果证明解决方案非常简单。

卸载 Kiwisolver：

pip3 uninstall kiwisolver 

然后重新安装 Kiwisolver：

pip3 install kiwisolver
