Question

我试图运行一个需要matplotlib的python程序，我已经通过pip安装了它。我在我的Mac上本地运行Python 3.6，更新了我的.bash_profile以反映这一点。有问题的进口线如下所示：

import matplotlib.pyplot as plt

以下是我看到的错误消息，您可以从主题行中找出：

ModuleNotFoundError: No module named 'matplotlib'

如果我尝试pip install matplotlib，我会看到这些：

Requirement already satisfied: matplotlib in /usr/local/lib/python3.6/site-packages
Requirement already satisfied: python-dateutil in /usr/local/lib/python3.6/site-packages (from matplotlib)
Requirement already satisfied: numpy>=1.7.1 in /usr/local/lib/python3.6/site-packages (from matplotlib)
Requirement already satisfied: pyparsing!=2.0.0,!=2.0.4,!=2.1.2,!=2.1.6,>=1.5.6 in /usr/local/lib/python3.6/site-packages (from matplotlib)
Requirement already satisfied: cycler>=0.10 in /usr/local/lib/python3.6/site-packages (from matplotlib)
Requirement already satisfied: pytz in /usr/local/lib/python3.6/site-packages (from matplotlib)
Requirement already satisfied: six>=1.10 in /usr/local/lib/python3.6/site-packages (from matplotlib)

我引用了其他一些帖子，例如this和this，但没有太多运气。我是否忽略了一个我没有完成的答案，或者它可能是其他的东西？感谢您的时间。

Answer 1

使用pip3 install matplotlib安装matlplot lib。默认情况下，pip将安装2.7的本地包，因为它是本机的。使用pip3使其特定于python 3，并确保只有一个版本的python 3

Answer 2

从文件执行此功能： -

import pip
pip.main(["install","matplotlib"])
