I followed the installation instructions for conda
<http://doc.sagemath.org/html/en/installation/conda.html> with both
python=3.6 (the most recent version that could install sage without
conflicts) and then python=2.7 (the one specifically cited in the
instructions) on macOS 10.13.6, using miniconda3.7. Both complete
installation happily, but sage immediately dies in both environment.s
I have never used Sage before, so I have no Sage configuration, and I had
no input history during the session because I literally just typed `sage`
on the command line and it failed. I use conda frequently, and don't
usually
have problems, so I doubt that it's anything very specific to my setup.
Both 3.6 and 2.7 fail in the same way: there's a missing symbol from some
dylib. The symbol is
__ZNSt3__16vectorIN5GiNaC2exENS_9allocatorIS2_EEE10deallocateEv
which demangles to
std::__1::vector<GiNaC::ex, std::__1::allocator<GiNaC::ex>
>::deallocate()
So I guess that's not getting included in lib, somehow. The full report
for 2.7 is attached — though the 3.6 report is essentially identical.
I've searched through every dylib that conda installs in envs/sage/lib, and
the only similar symbol I find is
__ZNSt3__16vectorIN5GiNaC2exENS_9allocatorIS2_EEE13__vdeallocateEv
which is in libpynac.dylib -> libpynac.18.dylib, and demangles to
std::__1::vector<GiNaC::ex, std::__1::allocator<GiNaC::ex>
>::__vdeallocate()
I wonder if it's related to https://github.com/pynac/pynac/issues/239.
I appreciate any help you can give me. Thanks!
