thanks, fixed

From a fresh git clone + pull develop on Ubuntu 16.04 x86_64 i7-6700HQ + 16 MB RAM, parallel (-j8) build OK and make ptestlong successful.

Hi,

It seems that the three.js viewer is broken in this release: running
show(sphere(), viewer='threejs')
in a Jupyter notebook results in a blank scene, along with the following warnings:
[W 21:07:03.945 NotebookApp] 404 GET /home/eric/sage/7.6.beta5/local/share/threejs/three.min.js (127.0.0.1) 5.54ms referer=None

On the same computer, everything is all right with 7.6.beta4.

Eric.

it works for me.  Perhaps you should run

sage -f threejs

and see if it helps.

No, it does not help.
Note that the issue is with the notebook (either Jupyter or legacy); in the console mode, it works.

Eric.

[Steven Trogdon]

Similar issue here with the exception that I have no warnings. The 'sphere' briefly appears and then disappears from the cell.

[Dima Pasechnik]

oh, right, sorry, I didn't pay attention. Indeed it works for me in console mode, but in jupyter nb.

(where I don't see any warnings or images).

On js console I see

Hi,

Thanks to Paul Masson, the fix of the threejs issue is at
