python - Python 3.3.5控制台无法在PyCharm 2016.3.1中启动

拜托，你能帮忙吗？我无法在PyCharm中启动python控制台。尝试了所有可用选项并浏览了文档，但无法弄清楚这一点。任何帮助，将不胜感激。请在下面找到我在控制台中看到的错误...

操作系统：Win 10

最佳答案

好吧，经过很多讨论之后：
将解释器更改为其他版本（至Python 3.5.x）可以完成此工作。这让我想知道IPython是否是问题所在。

问题在于，适用于Python 3.3.5的IPython不适用于PyCharm。 IPython版本5由PyCharm安装，但不适用于Python 3.3.5。

我先使用“ Conda卸载”删除了IPython，然后使用“ Conda clean”删除了IPython，然后重新启动了控制台，然后它像一个魅力一样工作了。

在本质上：
1.退出皮查姆
2.删除IPython-使用“ Conda删除/卸载”，然后使用“ conda clean”完全删除它。
3.重新启动Pycharm，并允许其重新导入所有“骨骼”
4.重新启动控制台。
