如何使用conda安装pydot? [英] How can I use conda to install pydot?

问题描述

通过遵循一些sklearn文档，尝试生成决策树的一些PDF，但是无法在我的机器上安装Pydot.有什么方法可以使用conda安装程序来安装pydot软件包吗?根据我看到的命令行错误，可能是64位问题.我使用binstar搜索来找到打包频道:

Trying to generate some PDF's of decision trees by following some of the sklearn documentation, but can't get Pydot on my machine. Is there any way to use the conda installer to install the pydot package? Based on the command line errors I'm seeing, it may be a 64bit issue. I use binstar search to find the package channel:

C:\binstar search -t conda 

建议使用以下方法详细查看软件包

Which gives the recommendation of looking at the packages in detail using

binstar show j14r/pydot

然后告诉我

conda install --channel https://conda.binstar.org/j14r pydot

但是，当我运行conda install命令时，出现以下错误(列出的所有pydot软件包都存在相同的错误):

But when I run the conda install command, I get the following error (same error for all the pydot packages listed):

Fetching package metadata: ...
Error: No Packages found in current win-64 channels matching: pydot
You can search for this package with 

binstar search t conda pydot

这使我回到了这一切的开头.有任何想法吗?谢谢大家.

which sends me back to the beginning of this all. Any ideas? Thanks all.
