محاولة استخدام مكتبة Gevent في Python: "المستورد: لا يمكن استيراد Core Core"

Question

أنا أحاول استخدام جيفنت مكتبة في تطبيق Python أنا أكتب. ومع ذلك ، يبدو أن كل من Easy_install وتثبيته يدويًا يفشل. أي اقتراحات؟

Python 2.6.2 (r262:71600, Aug  5 2009, 10:31:21) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] on linux2

Answer 1

حدث الخطأ ببساطة من خلال محاولة تشغيل برنامج نصي من دليل مصدر المشروع. التغيير إلى أي دليل آخر والقيام بـ "الاستيراد" يعمل بشكل جيد. مزيد من المعلومات هنا على قائمة البريد Gevent.

Answer 2

لقد أجبت على سؤالك على القائمة البريدية.

راجع للشغل ، هل تستخدم الإصدار 0.10.0 من جيفنت؟ إنه قديم! الأخير هو 0.12.0.
