Cannot start jupyter notebook

When I try to start (any) jupyter notebook directly, I get the following error:

 Traceback (most recent call last):
  File "/usr/bin/jupyter-notebook", line 11, in <module>
    sys.exit(main())
  File "/usr/lib/python2.7/site-packages/jupyter_core/application.py",     line 266, in launch_instance
    return super(JupyterApp, cls).launch_instance(argv=argv, **kwargs)
  File "/usr/lib/python2.7/site-    packages/traitlets/config/application.py", line 658, in launch_instance
    app.start()
  File "/usr/lib/python2.7/site-packages/notebook/notebookapp.py",     line 1784, in start
    self.launch_browser()
  File "/usr/lib/python2.7/site-packages/notebook/notebookapp.py",     line 1742, in launch_browser
    with open(fd, 'w', encoding='utf-8') as fh:
TypeError: coercing to Unicode: need string or buffer, int found

However, if I only start jupyter on some directory, I can open notebooks through browser just fine.

jupyter version: 4.4.0

python version: 2.7.15

OS: Fedora 29

It was a problem introduced in notebook=5.7.3. Running with 5.7.2 works.

The problem was introduced in #4260 and backported to the 5.7.x branch in #4265.

Fix at #4340.

Fix should be part of notebook 5.7.5 when it is released.

Assuming you are using the Anaconda for Jupyter Notebook, try using the update option. Use the following code "conda update anaconda" in the Terminal.
