Except for the weird GAP workspace test in assigned_names.py (which
*always* fails in ptestlong, passes when rerun separately), now all
tests pass for me on Linux x86_64 (Haswell-EP; with Sage's GCC 4.9.3).

Thanks!

Any idea?

[Vincent Delecroix]

Hi Eric,

I guess it comes from #19213 (that assumes that pip is installed).
#21291 is likely to solve the issue.

Vincent

[leif]

Again, this one is probably https://trac.sagemath.org/ticket/15585 .

Hi Eric,

Thank you Vincent! I've installed the Ubuntu package python-pip and run make again: the build was successfull. I've got some message though:

[sagelib-7.4.beta1] make[3] : on entre dans le répertoire « /home/eric/sage/beta1/src »

[sagelib-7.4.beta1] python -u setup.py install

[sagelib-7.4.beta1]     from pip import main
[sagelib-7.4.beta1] ImportError: No module named pip

but it did not halt the compilation and the built sage seems to work fine.

Should python-pip be added to the prerequisites list
http://doc.sagemath.org/html/en/installation/source.html#prerequisites
?

Best regards,

Eric.

**********************************************************************

[Dima Pasechnik]

yes, I have already seen and reported the latter.

For me, installing said module using "sage --pip   service_identity" helped.

So this seems that sagenb package should take care of installing this, although I'm not 100% sure.
