Question

我正在使用Mac，

我尝试使用ggplot如下

import matplotlib.pyplot as plt
plt.style.use('ggplot')

但我总是收到像

这样的错误

File "/Users/Desktop/code.py", line 4, in <module>
    plt.style.use('ggplot')
AttributeError: 'module' object has no attribute 'style'

我一直在检查找到解决方案，但我不知道我在哪里弄错了。有评论吗？

如上所述，我必须升级matplotlib但是，我收到了错误我的python版本是2.7 所以我试过这个

pip2 install matplotlib

这是错误

或者我试过

sudo port install py27-pip

这是错误

或者我试过这个

python get-pip.py
#Requirement already up-to-date: pip in /Library/Python/2.7/site-packages

然后

pip install matplotlib

错误如下

pip2 install -U matplotlib

或

sudo pip2 install -U matplotlib

它给我带来了很多错误，只是在底部吹了几行

如果我使用sudo

，则相同

"[Errno 1] Operation not permitted: '/tmp/pip-5PMqIK-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pytz'")]

Answer 1

一种方法是做

sudo pip2 install -U matplotlib --ignore-installed six

你必须使用 - ignore-installed six ，因为OS安装了六个1.4.1并且如果试图卸载它（因为awscli依赖于botocore，botocore依赖于python -dateutil和python-dateutil依赖于六个＆gt; = 1.5）它没有权限这样做，因为系统完整性保护甚至不允许root修改这些目录。

此处突出显示https://github.com/pypa/pip/issues/3165

执行此操作后，您可以将matplotlib的版本检查为

python -c 'import matplotlib; print matplotlib.__version__'

如果您收到错误提及

/usr/local/lib/python2.7/dist-packages/matplotlib/font_manager.py:273: UserWarning: Matplotlib is building the font cache using fc-list. This may take a moment.
  warnings.warn('Matplotlib is building the font cache using fc-list. This may take a moment.')

，然后很容易解决它

打开终端

然后写python

然后

>>> import matplotlib as mpl
>>> mpl.get_configdir()

了解完路径后，请转到finder -----＆gt; Go 搜索文件夹并删除fontList

然后再次运行程序，您将再次收到警告并解决。更多信息，也可以在这里找到第二部分 matplotlib taking time when being imported
