Have you backported libjs-codemirror? There is a big version mismatch
between jessie and stretch (2.3 vs 5.4).

Unfortunately, since the build involves reconstructing the javascript
package tree upstream expects to get from npm, and that the directory
structures in /usr/share/javascript don't necessarily match the layout
you get from npm, lots of symlinks are needed and it's probably
non-robust against different versions.

The dependency in this case isn't versioned because the version
available in stretch is any case not technically new enough for the
package (5.4 available vs 5.8 requested), but it *appears* to work.

The following required files are missing: ['notebook/static/notebook/js/main.min.js', 'notebook/static/tree/js/main.min.js', 'notebook/static/edit/js/main.min.js', 'notebook/static/terminal/js/main.min.js', 'notebook/static/auth/js/main.min.js', 'notebook/static/style/ipython.min.css', 'notebook/static/style/style.min.css']
