无法使用 pip 运行 jupyter notebook

Question

只是想用 pip 运行 jupyter notebook。到底发生了什么？我尝试像“python -m notebook”一样运行它，因为“jupyter notebook”或“notebook”甚至都无法被识别。

C:\**\**>python -m notebook

您通过 pip 在本地安装的 jupyter 与您的 Anaconda 安装冲突。在某些情况下，您可能需要多个 python 实例（例如，如果您需要使用不同版本的 python 测试代码，或者某些应用程序需要单独的实例，但您似乎希望将安装限制为仅单个实例。

记得使用环境来保持你的包列表干净。
