将Orange安装到虚拟环境中

Question

带有原生Python 2.7.6的Linux Mint 17.1。

INSTALL.txt中列出的所有pre-reqs : 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- ipython qt4-gl build-essential python-pip python-scipy python-pyparsing ipython python-matplotlib

有没有人在virtualenv中安装了orange？我正在尝试使用pip将Orange安装到一个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

安装开始时已经足够好了：

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

在这一点上，有一个暂停(编译)，最后是一个很长的错误列表，我已经在这里发布了：http://pastebin.com/VZWyGjfz和我已经包括了下面的最后几行：

Answer 1

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，即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、...通过使用virtualenv --system-site-packages venv创建虚拟环境。
