--- Comment #4 from Osamu Matsuda <omatsuda...@gmail.com> --- In fact, these necessary "nbformat.v4*.json" files are also there in /usr/ports/devel/py-nbformat/work-py39/nbformat-5.6.1/nbformat/v4 during the build of nbformat-5.6.1. So copying these missing files to /usr/local/lib/python3.9/site-packages/nbformat/v4 would be reasonable. -- You are receiving this mail because: You are on the CC list for the bug.
