Matplotlib AttributeError:'模块'对象没有属性'popall' [英] Matplotlib AttributeError: 'module' object has no attribute 'popall'

问题描述

当尝试使用pyplot绘制图形时，我正在运行以下代码:

When trying to plot a graph with pyplot I am running the following code:

from matplotlib import pyplot as plt

x = [6, 5, 4]
y = [3, 4, 5]

plt.plot(x, y)
plt.show()

这将返回以下错误:

AttributeError: 'module' object has no attribute 'popall'

我的 matplotlib 一直运行良好，但是在我昨天使用 homebrew 和 pip 重新安装它后出现了这个错误.我正在运行以下内容:

My matplotlib has always worked fine, but this error popped up after I reinstalled it using homebrew and pip yesterday. I am running the following:

OS: Mac OS Sierra 10.12.5
Python: 2.7.13
Matplotlib: 2.0.2

此后，我再次尝试完全重新安装matplotlib和python，但仍然收到相同的错误.我还尝试了多种编辑器(Jupiter，Sublime，Terminal).

I have tried a complete reinstall of matplotlib and python again since but still getting the same error. I have also tried multiple editors (Jupiter, Sublime, Terminal).

任何帮助将不胜感激！

推荐答案

我已经解决了我的问题，尽管我不确定为什么会解决.

I have solved my problem although I am not entirely sure why this has solved it.

我使用 pip卸载matplotlib 删除了python安装，还更新了〜/.zshrc 和〜/.bash_profile 路径包含:

I used pip uninstall matplotlib, to remove the python install, and also updated my ~/.zshrc and ~/.bash_profile paths to contain:

HomeBrew:

导出PATH =/usr/local/bin:$ PATH

蟒蛇:

导出PATH =/usr/local/share/python:$ PATH

这已经解决了这个问题.我猜测问题是由两次安装matplotlib引起的，并且路径位于〜/.bash_proile 中，而不是〜/.zshrc 中.

This has solved the issue. I am guessing the issue was caused by having two install of matplotlib and having the path in ~/.bash_proile but not the ~/.zshrc.
