'USE=-doc MAKEOPTS=-j1 emerge -v1 notebook' works. The same error occurs when just trying to view a notebook with "jupyter notebook". It seems to be an incompatibility with www-servers/tornado-5 which has just been unmasked. Downgrading to www-servers/tornado-4.5.3 fixes the problem. So the dev-python/notebook ebuild should either require tornado<5 for now or include a compatibility fix. Confirming this issue. Was able to install dev-python/notebook successfully, but encountered the error when running "juptyer notebook". Downgrading to www-servers/tornado-4.5.3 (from version 5.0.2) solved the problem. Compatibility with Tornado 5 was added to Jupyter Notebook 5.3: https://github.com/jupyter/notebook/pull/3034/. From the setup.py of notebook in the current master: install_requires = [ .. # pyzmq>=17 is not technically necessary, # but hopefully avoids incompatibilities with Tornado 5. April 2018 'pyzmq>=17', .. ], Thus a possible notebook version bump might depend on https://bugs.gentoo.org/648088. Closing bugs reported for old versions, no longer in ::gentoo. Please reopen if you can still reproduce. |
