ubuntu14.04 python3.4無法pip3 matplotlib

Question

已搜索其他類似的問題，但沒有成功。我是否必須回到Python 2.7？

英特爾32b桌面上的ubuntu 14.04。使用Python2.7一切正常。現在使用Ubuntu軟件中心爲Python3.4安裝了Idle。它的工作原理，但

import matplotlib 

結果

matplotlib not found 

然後

pip3 install matplotlib 

導致巨大的良性尋找輸出量，但有錯誤結束。這裏是最後的PIP日誌文件：

此錯誤

error: [Errno 13] Permission denied: '/usr/local/lib/python3.4/dist-packages/pylab.py' 

表示腳本試圖在目錄/usr/local寫。

超級用戶運行以下命令：

sudo pip3 install matplotlib
