Probleme mit der Installation von Cython in Windows 7

Question

Ich bin ein neuer Anfänger in Python und versuchen, Cython in Windows 7 zu installieren (ich verwende Anaconda mit Python zu kodieren). Ich erlebe ein Problem bei der Installation von Cython in meinem Computer:

Wie kann ich es lösen und Cython erfolgreich installieren? Vielen Dank !

Answer 1

Wenn Sie Anaconda die erste Anlaufstelle verwenden, wenn sollten neue Module zu installieren sein Conda zu verwenden:

conda install cython

Dies wird ein Binärpaket die Notwendigkeit einer Zusammenstellung installieren, zu vermeiden (was bedeutet, Sie benötigen keinen C/C++ - Compiler installiert).

Gelegentlich werden Sie über ein Modul kommen, dass nicht vorgesehen ist, in welchem ​​Fall es OK ist, zu tun:

pip install nameofmissingmodule
