无法使用Jupyter Lab或Jupyter Notebook (FileNotFoundError：[WinError 2]系统找不到指定的文件)运行任何ipynb文件
无法使用Jupyter Lab或Jupyter Notebook (FileNotFoundError：[WinError 2]系统找不到指定的文件)运行任何ipynb文件
提问于 2018-06-05 02:56:35
我在Win10上运行了JupyterLab/JupyterNotebook，同时在Windows10上运行了Python和PyCharm。我曾尝试重新安装Anaconda分发版或Python的任何其他实例，但每次启动JupyterLab/Notebook时都会出现相同的错误。我也尝试过用win7在远程服务器上运行它，但它给出了完全相同的错误。我认为我在安装Anaconda、Python和PyCharm时犯了同样的错误，现在我无法将其还原。有什么建议吗？

看起来和nb_conda有关。一旦我使用下面的命令重新安装了nb_conda，它就对我起作用了。
conda install nb_condaStack Overflow用户

这可能是因为您删除了一个env，但仍然有对该env的引用。要解决此问题，请在命令提示符下运行以下命令：
python -m ipykernel install --user希望这能有所帮助:)

我也有同样的问题。我找到了解决方案here (请点击链接进一步解释)，在我的虚拟环境中通过在cmd中键入以下命令，问题就解决了：
python -m ipykernel install --user
我希望它能有所帮助。
