Having a problem installing dash through pip

Hey everyone, I’ve got a small problem when installing dash-related packages through pip install command, it tells me that package werkzeug and package nbformat are not capable to upgrade.

Any suggestions?

enviroment : Anaconda Python 3.5

As you are using anaconda could you create a new environment that would not have the werkseug already installed. Then attempt the same install?

Thank your for the advice, it did work. I establish a new environment in py 3.6, which solves the problem perfectly.:grinning:
