在Anaconda环境中安装pydot和graphviz软件包 [英] Installing pydot and graphviz packages in Anaconda environment

问题描述

我希望能够在Python中创建图形决策树，并且当前正在尝试同时安装pydot和graphviz.

I want to be able to create graphical decision trees in Python, and I am currently trying to install both pydot and graphviz.

我正在将Anaconda作为我的环境(以及Spyder)，并尝试运行以下代码行

I am using Anaconda as my environment (along with Spyder), and have tried to run the following lines of code

conda install -c https://conda.binstar.org/t/TOKEN/j14r pydot

结果

Error: unknown host: http://repo.continuum.io/pkgs/pro/win-32/
Error: unknown host: http://repo.continuum.io/pkgs/free/win-32/
Error: unknown host: https://conda.binstar.org/t/TOKEN/j14r/win-32/
Error: No packages found matching: pydot

我也尝试过使用pip install pydot和pip install graphviz来获得类似的结果:

I have also tried using pip install pydot and pip install graphviz with similar results:

Downloading/unpacking pydot
  Cannot fetch index base URL https://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement pydot
Cleaning up...
No distributions at all found for pydot
Storing complete log in [...]

试图弄清楚如何解决这个问题我感到很无聊，所以我希望在那里的任何人都可以给我一些提示.

I am getting pretty bored at trying to figure out how to go about this, so I was hoping anyone out there could give me some tips perhaps.

谢谢

This answer is overdue but this post helped me (together with this one that mentions the installation order), so hopefully this answer will help someone else. I'm using Ubuntu 14.04 and Python 2.7.
