我正在尝试使用pip在本地安装软件包.它曾经使用--user但现在当我尝试它时,它找到包的版本,/usr/local/lib/然后不在本地安装它.通常情况下,将安装在的东西~/.local,但现在它只是检查包装上的系统级目录,如果它的存在,它不安装它(这是不是我想要的),如果它不存在,它会尝试安装它在/usr/local/lib其中我没有写权限.例如:

$ pip install --user rpy2
Requirement already satisfied (use --upgrade to upgrade): rpy2 in /usr/local/lib/python2.7/dist-packages/

如何使pip install --user总是转到~/.local而不是系统范围的目录？

pip识别全局安装包..？!:-(

我用virtualenvwrapper preactivate钩来清洁PYTHONPATH,

export PYTHONPATH="" 

然后echo $ PYTHONPATH返回空字符串,但这没有帮助.

怎么了？
