Unable to build site locally

[rossbar]

I've attempted to build the site locally through various methods, including via the Makefile and with jupyter-book. So far, I haven't been successful with either approach. When I try to build with the Makefile (after manually installing the dependencies to work around #63) I see the following:

make[1]: *** book: No such file or directory.  Stop.
make: *** [Makefile:37: html] Error 2

I tried working through some of the other steps in the Makefile manually, but haven't been able to progress to getting the site built.

When I try with jupyter-book (e.g. jb build .) I see the following:

jb build output

You may need to migrate from the old format, using:
    jupyter-book toc migrate /home/ross/repos/skimage-tutorials/_toc.yml -o /home/ross/repos/skimage-tutorials/_toc.yml
