的virtualenv会为蟒蛇2.7

Question

不是符号链接warnings.py我有上清醒创建与python2.7的virtualenv（1.5.2）中的问题。看起来，像virtualenv正在跳过为warnings.py创建符号链接。

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

有与python2.6的创建virtualenv中没有问题。

Answer 1

所以我检查virtualenv.py代码，它有一个列表REQUIRED_MODULES，似乎有模块的名称中附加新的环境/ lib目录。该列表由模块“警告”满足条件后延伸：

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

Python版本正确中标识，所以不存在与virtualenv.py没有问题。指定我使用的是已安装的virtualenv，而不是文件virtualenv.py。

从蟒蛇的dist-包删除文件virtualenv.pyc后，问题消失了。所以看起来像编译好的virtualenv文件有问题 - 看起来像pythons版本检查的问题。
