使用PyCharm PygraphViz导入错误

Question

我相信我已经在我的Debian版本上安装了pygraphviz.如果我从命令行运行Python,我可以导入它:

jon@debian:~/anaconda3/bin$ ipython
Python 3.5.1 |Continuum Analytics, Inc.| (default, Dec  7 2015, 11:17:45) 
Type "copyright", "credits" or "license" for more information.

IPython 4.1.2 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object', use 'object??' for extra details.

In [1]: import pygraphviz

In [2]: 

但是,如果我从PyCharm中的Python控制台尝试相同的操作,我会收到此错误:

/home/jon/anaconda3/bin/python /home/jon/apps/pycharm-community-5.0.4/helpers/pydev/pydevconsole.py 59089 41751

    module = self._system_import(name, *args, **kwargs)
ImportError: No module named 'pygraphviz'

我注意到在第一个例子中,Python版本是

Python 3.5.1 |Continuum Analytics, Inc.| (default, Dec  7 2015, 11:17:45) 

而在第二个例子中,版本是:

Python 3.5.1 |Anaconda 2.5.0 (32-bit)| (default, Dec  7 2015, 11:17:45) 

所以失败的第二个例子似乎是32位(作为旁注,为什么它会安装32位版本？)

我的/ anaconda3/envs文件夹是空的.

据我所知,我只在Conda中安装了一个Python环境.

所以我的问题是......为什么导入在PyCharm中失败,为什么当我只安装了一个版本时,它似乎运行了32位版本的Python？

本指南应该帮助您配置所有内容，包括库的自定义路径。

解释器没问题，它已经指向 Anaconda 的发行版。但在“默认项目”设置下，有一个控制台选项：“构建、执行、部署”->“控制台”->“Python 控制台”。看看你能在那里摆弄什么。如果你不能让它工作，也许可以发布你的配置。

此外，您应该使用虚拟环境。请参阅这篇文章了解更多信息。
