Python中的隐式模块搜索？
我正在更全面地了解Python虚拟环境，以了解廉价托管解决方案和开发平台中的可移植性问题，并且有些内容我不明白。
我一直在构建虚拟环境，但我没有看到完整的隔离，我需要将虚拟环境复制到主机，假设主机没有安装python
问题是，我将建立，这不是完全从装置P隔离的平台P -斌/ python2.6的- LIB / python2.6的/站点包
PATH更改为仅包含P / bin /
PYTHONPATH是空白的
完美的作品。 但是，它仍然访问系统目录来解决不在虚拟环境中的内容。 为什么？？
在这种情况下P = / tmp / pinax2 /`
进口系统
打印sys.path

你在说virtualenv吗？ 创建排除所有现有网站包的虚拟环境时有一个选项。 我认为这就是你想要的。
virtualenv --no-site-packages env
