<p>فشل Virtualenv - فشلت عجلة setuptools pip مع رمز الخطأ 2</p>

أنا أركض على Ubuntu-12.04:

نقطة - الإصدار
نقطة 8.0.2 من /usr/local/lib/python2.7/dist-packages (python 2.7)

Virtualenv - الإصدار
14.0.6

فشل Virtualenv في إنشاء البيئة. لا أعرف لماذا تعتقد أنه من المفترض أن تستخدم النقطة 7.0.1 ، عند تثبيت النقطة 8.0.2.
حاولت إعادة تثبيت pip (أي إزالة الحزمة المناسبة ، التثبيت عبر ez_setup) ، virtualenv - لم ينجح شيء.
على الأجهزة الأخرى ، كان 14.0.6 يعمل بشكل جيد ، وهذا فقط هو الذي يعطيني وقتًا عصيبًا.
سيكون موضع تقدير أي مساعدة!

أرفق السجل ، وأتبع بيئة النقطة:
