AttributeError的：「模塊」對象有沒有屬性「風格」

Question

我使用的是Mac，

我嘗試使用ggplot如下

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

，但我總是得到一個錯誤，如

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

我一直在檢查找到一個解決方案，但我不知道我在哪裏犯了一個錯誤。任何意見 ？

如前所述的打擊，我必須然而升級matplotlib，我得到錯誤 我的Python版本是2.7 所以我想這個

​​

，這裏是錯誤

或者我試過

sudo port install py27-pip 

，這裏是錯誤

Password:

或我想這

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

然後

pip install matplotlib 

的錯誤有以下幾種

pip2 install -U matplotlib 

或

sudo pip2 install -U matplotlib 

它給了我很多的錯誤只是在底部幾行自爆

同樣的，如果我做sudo

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

Answer 1

一種方式是做

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

您必須使用--ignore-installed六因爲操作系統附帶六個1.4.1安裝，如果試圖卸載它（因爲awscli取決於botocore，botocore取決於python-dateutil和python-dateutil取決於六> = 1.5）它不有權這樣做，因爲系統完整性保護甚至不允許root修改這些目錄。

這是這裏強調https://github.com/pypa/pip/issues/3165

完成這一步之後，您可以檢查版本的matplotlib作爲

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

如果你得到你的

/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.') 

提到的錯誤，那麼很容易解決它

open terminal

然後寫python

然後

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

一旦你知道路徑，進入finder ----->Go 還有搜索文件夾，刪除fontList

然後再次運行您的程序，您將再次收到警告並解決問題。 更多信息，可以在這裏找到第二部分 matplotlib taking time when being imported
