Sanal ortamım (Python) PYTHONPATH'ımın bozulmasına neden oluyor mu?

Question

/etc/profilimde PYTHONPATH öğesini bir şey olarak ayarladım.

Ama source myvirtual-env

Ve sonra python bunu yaparken:

>>> import sys 
>>> print sys.path 

benim yolları yerde göremiyorum.

Answer 1

Bu, virtualenv'nin noktasıdır. Kurulumun geri kalanından miras kalmaz. Bir PYTHONPATH istiyorsanız, açıkça bir tane ayarlamanız gerekir.

Bu djangousers post muhtemelen yararlıdır, virtualenvwrapper bu sorunu çözmek için kullanmak istersiniz.

Answer 2

Windows XP'de Python 2.7, virtualenv 1.7.1.2 ile ilgili problemi görmüyorum ve Paul McMillan'ın cevabının yanlış olduğundan şüpheleniyorum.
