無法在IPython中導入sympy，scipy

我無法使用Ipython從Mac終端導入scipy，sympy。我的蟒蛇分佈是樹冠，這也是我的默認Python環境（IPython的化名爲/庫/ Enthought/Canopy_64bit /用戶/箱/ IPython中）。無法在IPython中導入sympy，scipy

的抗工系統是OS X 10.9。

的錯誤都嘗試是：

重新安裝模塊。升級小牛後發生了很多問題。 – moenad

我應該使用Canopy Package Manager還是通過終端和Mac端口重新安裝它？ – bergercookie

如果您想修復Canopy，請使用Canopy的包管理器或enpkg命令行。 – jonathanrocher

我建議你刪除：

~/Library/Enthought/Canopy_64bit/User/

，並重新啓動篷。標準軟件包將被重新安裝。您將需要重新安裝/更新您之前添加或更新的任何軟件包。

不要在Canopy上使用mac端口。它們不兼容。
