无法使用 pip 运行 jupyter notebook

Question

Just trying to run jupyter notebook with pip. What the hell is happening? I tried to run it like this "python -m notebook", because just "jupyter notebook" or just "notebook" doesn't even get recognized.

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

Your local installation of jupyter via pip is conflicting with your Anaconda installation. There are some situations where you may need more than one instance of python (eg if you need to test code with different versions of python, or some applications require a separate instance, but you seem like you might want to limit your installations to just a single instance.

Remember to use environments to keep your package list clean.
