QuantLib builds out of the box. For PyQL, I need Cython >0.18; installed version is 0.15. If I try a local install:
pip install --user --upgrade --ignore-installed cython
pip tries to uninstall the system version, which of course fails. Any idea how to proceed?Sat, 01 Feb 2014 13:01:43 -0600https://ask.sagemath.org/question/10978/how-to-upgrade-a-python-package-with-pip/Answer by John Palmieri for <p>I'm trying to set up QuantLib and PyQL on cloud.sagemath.

https://ask.sagemath.org/question/10978/how-to-upgrade-a-python-package-with-pip/?answer=25629#post-id-25629Hello,
Soon we will have pip as a standard package. So in sage version greater or equal to 6.5 just do
sage -pip install ...
In Sage version 6.4 you can already do the above command but first you need to install pip through
sage -i pip
For more information about the integration of pip see:
- [trac ticket #16479](http://trac.sagemath.org/ticket/16479): package for pip the Python installer
- [trac ticket #17155](http://trac.sagemath.org/ticket/17155): add "sage -installed" and "sage -pip" commands
- [trac ticket #17368](http://trac.sagemath.org/ticket/17368): Make pip a standard package
