好的，经过多次讨论：将解释器更改为不同的版本（到Python 3.5.x）使这项工作成为可能。这让我想知道IPython是否是问题..它肯定是!!

问题是Python 3.3.5的IPython不能与PyCharm一起使用。 IPython版本5由PyCharm安装，但不适用于Python 3.3.5。

我使用'Conda uninstall'删除了IPython，然后'Conda clean'并重新启动了控制台，然后它就像魅力一样......

实质上： 1.退出Pycharm 2.删除IPython - 使用'Conda删除/卸载'然后'conda clean'完全摆脱它。 3.重新启动Pycharm并允许它重新导入所有'骷髅' 4.重新启动控制台。

Answer 2

我在Fedora 24上遇到了类似的问题。出于某种原因，Fedora仍然提供IPython 3.x：/我只是使用安装了IPython 6.0.0的pip3 install ipython --upgrade升级它并且它可以工作：D

Python 3.3.5控制台无法在PyCharm 2016.3.1中启动
