Linux Mint 17.1 与本机 Python 2.7.6。

INSTALL.txt 中列出的所有先决条件： python-numpy libqt4-opengl-dev libqt4-dev cmake qt4-qmake python-sip-dev python-qt4 python-qt4-dev python-qwt5-qt4 python-sip graphviz python- networkx python-imaging python-qt4-gl build-essential python-pip python-scipy python-pyparsing ipython python-matplotlib

有没有人将橙色安装到虚拟环境中？我正在尝试使用 pip 将 Orange 安装到 virtualenv 中，如下所示：

$ cd ~/venv/
$ mkdir orange
$ cd orange
$ virtualenv venv
$ source venv/bin/activate
$ pip install --global-option="build_pyqt_ext" orange

安装开始得很好：

Collecting orange
  Using cached Orange-2.7.8.tar.gz
Requirement already satisfied (use --upgrade to upgrade): setuptools in ./venv/lib/python2.7/site-packages (from orange)
Collecting numpy (from orange)
  Using cached numpy-1.9.1.tar.gz
    Running from numpy source directory.
Collecting scipy (from orange)
  Using cached scipy-0.15.0.tar.gz

此时会出现暂停（编译），最终会出现一长串错误，我在这里发布了这些错误：http: //pastebin.com/VZWyGjfz，我在下面包含了最后几行：

这似乎是 pip 或 scipy 的设置脚本中的错误（您可以尝试单独安装 numpy、scipy ie 吗pip install numpy && pip install scipy）。

请注意，在任何情况下，您都应该使用系统提供的 numpy、scipy、... 包virtualenv --system-site-packages venv来创建虚拟环境。
