Jinja2 is too old

[vbraun]

If you try to save ipython notebooks as pdf, you'll get the following error

$ sage -ipython nbconvert Untitled.ipynb --to pdf
[...]
  File "/home/vbraun/Code/sage.git/local/lib/python2.7/site-packages/IPython/nbconvert/exporters/../templates/latex/skeleton/null.tplx", line 34, in block "any_cell"

    ((( add_prompt(cell.source | highlight_code(strip_verbatim=True), cell, 'In ', 'incolor') )))
UndefinedError: 'add_prompt' is undefined

Workaround is sage -pip install --upgrade jinja2

New vanilla tarball is already on the Sage mirror.

Well, that will put you on par with sage-on-gentoo. Using that version since last November. +ing.

Darn I reverted to my default state of not putting my name after breakfast.

Markupsafe is a new dependency of jinja...

comment:8

Indeed I hadn't checked that. From what I can see it is the only one (apart from setuptools and sphinx if you want to build the doc). It appears that docutils is not a dependency of jinja2 anymore, I guess that's were sphinx is coming in.

Jinja depends on Sphinx instead of docutils

comment:11

sphinx depends on docutils for the record...

Replying to @vbraun:

sphinx depends on docutils for the record...

That's a good record.

No implications for sagenb, I assume?

[kiwifb]

comment:14

None that I can see. Do you have something particular you want tested since I have the stuff in sage-on-gentoo at the 6.6.beta5 level?

comment:15

As long as templating and the server actually work and you don't see any obvious errors of that type, I guess it's okay. I think flask depends on jinja2, right?
