jupyter notebook installation issue using pip

Question

I had a problem with jupyter notebook. Every time I started a notebook, kernel died.

So, I decided to uninstall jupyter notebook using pip:

pip uninstall jupyter notebook

After successful uninstallation, I installed again, using same pip:

pip install jupyter notebook

Then, as usually, I typed in cmd:

jupyter notebook

But got this error:

'jupyter' is not recognized as an internal or external command, operable program or batch file.

So I checked the location of IPython, and found out that now the right file, which I want to call is jupyter-notebook, which different from jupyter notebook by dash sign. If I run jupyter-notebook from cmd everything works.

Can anyone explain, what happened and why the file now called jupyter-notebook?

Thank You

Solution

Because pip uses the legacy Python 2. Use pip3 to install:

pip3 install --upgrade pip
pip3 install jupyter
jupyter notebook  #to start jupyter notebook

I highly recommend installing Anaconda. Download Anaconda here.

Then use :

bash 

to install it.

Good Luck.

@SuatAtanPhD same result. I am just curious of why the syntax changed.

just an addition, if you are trying to re-install jupyter notebook, please make sure to uninstall it first pip3 uninstall jupyter notebook. Then pip3 install jupyter notebook. This worked for me for the latest versions.
