的virtualenv會爲蟒蛇2.7

Question

不是符號鏈接warnings.py我有上清醒創建與python2.7的virtualenv（1.5.2）中的問題。看起來，像virtualenv正在跳過爲warnings.py創建符號鏈接。

File warnings.py位於/usr/local/lib/python2.7/中。

有與python2.6的創建virtualenv中沒有問題。

Answer 1

所以我檢查virtualenv.py代碼，它有一個列表REQUIRED_MODULES，似乎有模塊的名稱中附加新的環境/ lib目錄。該列表由模塊「警告」滿足條件後延伸：

sys.version_info[:2] >= (2, 6) 

Python版本正確中標識，所以不存在與virtualenv.py沒有問題。指定我使用的是已安裝的virtualenv，而不是文件virtualenv.py。

從蟒蛇的dist-包刪除文件virtualenv.pyc後，問題消失了。所以看起來像編譯好的virtualenv文件有問題 - 看起來像pythons版本檢查的問題。
