For those who still have trouble launching Chrome automatically from cmd, try replacing
# c.NotebookApp.browser =''
in the file jupyter_notebook_config.py
with
import webbrowser
webbrowser.register('chrome', None, webbrowser.GenericBrowser('C:\Program Files (x86)\Google\Chrome\Application\chrome.exe'))
c.NotebookApp.browser = 'chrome'
or the appropriate location, there shouldn't be need to install anything via pip.
