在修改PATH變量以使某些庫安裝正常工作後，我發現使用％matplotlib魔術命令時，我的IPython Notebook（Ubuntu 14.04上的Enthought Canopy）會引發以下錯誤：GFORTRAN_1.4未找到
ImportError: /home/joe/Enthought/Canopy_64bit/User/bin/../lib/libgfortran.so.3: version `GFORTRAN_1.4' not found (required by /usr/lib/liblapack.so.3)
我在嘗試安裝python-bio-formats，pims和pylibtiff時也遇到這個錯誤。
同樣，任何想法讚賞。
編輯：完整的錯誤回溯：
