virtualenv不会对python 2.7进行符号链接warnings.py

我在使用Lucid上的python2.7创建virtualenv(1.5.2)时遇到问题.看起来像virtualenv正在跳过warnings.py的symlink创建.

文件warnings.py位于/usr/local/lib/python2.7/中.

使用python2.6创建virtualenv没有问题.

最佳答案

所以我检查了virtualenv.py代码,它有一个列表required_MODULES,它似乎有新的环境的/ lib目录中附加模块的名称.在满足条件后,此列表由模块“警告”扩展：

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

正确识别了python的版本,因此virtualenv.py没有问题.要指定我使用已安装的virtualenv,而不是文件virtualenv.py.

从python dist-packages中删除文件virtualenv.pyc后,问题就消失了.所以看起来像编译的virtualenv文件有问题 – 看起来像pythons版本检查的问题.
