I'm trying to change my Jupyter notebook starting directory by changing c.NotebookApp.notebook_dir 

c.NotebookApp.notebook_dir = ‘/Users/kai/Box Sync/Python’

as per https://github.com/ioos/conda-recipes/wiki/Customizing-the-notebook-settings

kaichens-MacBook-Air:~ kai$ jupyter notebook

Any help is appreciated!

This has nothing to do with jupyter: that character, and the one on the other end of your string, is not an ASCII apostrophe:

In [1]: str("‘")
Out[1]: '\xe2\x80\x98'

In [2]: str("'")
Out[2]: "'"

You'll need to replace both of those with apostrophes for your code to parse.
