Answer 1

Simpler installation with Anaconda

An alternative to using pip is Anaconda or Miniconda . It is great for installing scientific libraries such as Jupyter.

Anaconda

Anaconda is a full distribution of about 200 libraries including Jupyter. Just install it with given instruction as user (not root) and you should be good to go.

Miniconda

Miniconda is smaller. It includes Python and a few essential libraries. If Anconda seems to big, download and install Miniconda. Again, as user not as root. Then, install Jupyter with:

conda install jupyter

Answer 2

In your case it is complaining to the log file. If you can specify it it should solve the problem, as now it is not finding it.
