Question

我正在一台我没有管理员权限的服务器上工作，因此我已经在本地安装了软件包pip --user。为了让python看到这条路径，我将其添加到我的.profile：

export PYTHONPATH=$PYTHONPATH:/Users/delavega/Library/Python/2.7/lib/python/site-packages

这可以成功地将本地安装的软件包添加到python的路径中，这可以通过调用sys.path（）来证明。但是，IPython 不使用本地安装中的软件包，而是使用全局安装的软件包：/usr/local/lib/python2.7/site-packages

打印python和IPython的路径，我的本地站点包文件夹位于不同的位置但路径总体上有所不同：

的Python：

IPython的：

如您所见，路径不同。使用sys追加或预先添加IPython的路径不会改变加载的包

为什么这些路径不同，如何从本地安装加载IPython？

Answer 1

确保ipython是virtualenv-aware的最可靠方法是将pip安装到你的virtualenv中。

肯定有ipython_config.py hacks（http://rodesia.org/2012/09/04/making-ipython-virtualenv-aware/）试图给它一些意识，但YMMV。

Python和IPython路径不同
