在Ubuntu 12.04上通過pip安裝matplotlib 12.04

Question

我想在Ubuntu 12.04上使用matplotlib。所以我建立與PIP輪：

蟒蛇。本地/斌/ PIP輪--wheel-DIR =輪/ --build =編譯/ matplotlib

然後安裝成功：

蟒蛇。本地/斌/ PIP安裝--user --no指數--find鏈接=輪/ --build =編譯/ matplotlib

但是，當我試圖將其導入IPython中導入錯誤occures ：

In [1]: import matplotlib

In [2]: matplotlib.get_backend()
Out[2]: u'agg'

In [3]: import matplotlib.pyplot

ImportError

ImportError: /home/yefremat/.local/lib/python2.7/site-packages/matplotlib/_tri.so: undefined symbol: _ZNSt8__detail15_List_node_base9_M_unhookEv

可能是我在做一些錯誤嗎？或者可能有一種方法可以關閉對matplotlib的gui支持？

在此先感謝。

好的，問題出現在gcc版本中。在構建和創建包pip的輪子期間使用系統gcc（其版本是4.7.2）。我從virtualenv使用python，它是用gcc 4.4.3構建的。所以libstdC++庫的版本在IPython和pip使用的版本中是不同的。

與往常一樣，有兩種解決方案（甚至更多）：在輸入IPython之前將LD_PRELOAD環境變量與正確的libstdC++一起傳遞，或者在創建wheel和構建virtualenv時使用相同版本的gcc。我預備了最後一個。

謝謝大家。
