Python 没有名为_multiprocessing/的模块需要pyzmq>；=2.1.11

为了解决这个问题，我一直在仔细查看不同的错误消息，并且我已经运行了大量python 2.7和ipython的重新安装，但是我无法启动ipython笔记本

application.py

中的

catch\u config\u错误

会提示“trait”设置不正确，这超出了我的知识范围

我还对

“IPython.html要求pyzmq>=2.1.11”

感到非常困惑，因为

pip列表显示的是版本14

我有一种感觉，我可能有一些路径变量设置不正确，并且有一个文件夹
csvn中有python25文件夹吗

请参阅下面的错误消息和pip日志

好的，
原来我的C:\CSVN上安装了一个Python2.5的旧版本

我删除了它

使用卸载工具卸载了所有其他版本的python

然后我安装了Anaconda，现在一切正常

虽然Python25文件夹可能是主要问题，但我建议使用有效的卸载工具，因为windows控制面板中的工具可能不符合要求。
是的，您路径中的默认python解释器似乎不是刚刚安装的，而是安装到“C:\csvn\Python25”的某个旧版本。Pip为您的2.7 Python解释器安装软件包，但在您的Python25安装中当然看不到这些软件包。你实际上没有问特定的问题，因此很难给出答案。我想知道如何修复路径。如果我的csvn文件夹中有python27，请启动Ipython笔记本？我不是Windows用户，因此我可能不应该在这里给你提建议。在windows上设置python似乎并不简单。但是，如果搜索stackoverflow，您将找到许多常见问题的指南：如何编辑PATH变量：如何安装pip：这不是Windows特有的问题。我在Mac上也遇到了同样的错误。
