The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications? If you install everything into /usr/lib/python2....
该操作会创建 ENV/lib/pythonX.X/site-packages 目录 和 ENV/bin/python , 前者用来存放要安装的模块,后者就是隔离环境的Python解释器。 在virtualenv环境下使用此解释器(包括以 #!/path/to/ENV/bin/python 开头的脚本)时,使用的都是隔离环境下的模块。 (此外可更改setuptools、distribute的使用) S2、进入ENV,激...
Python bugfix releases 2.6.8, 2.7.3, 3.1.5 and 3.2.3 include a change that will cause "import random" to fail with "cannot import name urandom" on any virtualenv created on a Unix host with an earlier release of Python 2.6/2.7/3.1/3.2, if the underlying system Python is upgraded. ...

Now let's review the two problems I mentioned in the last section and see how they change with the power of PEP 582. For the first problem, the main cause is that the virtual environment is bound to a cloned Python interpreter on which the subsequent library searching based. It takes adv...
