In short: Install sage from conda-forge.
To install sage on your machine (without the need for root permissions):
Install Miniconda for Python 3 (Python 2 version fails to copy "Hängematte" which comes with rw)
export your PATH (and hash -r or rehash)
- Make sure your locale is UTF-8.
Add the conda-forge channel: conda config --add channels conda-forge
Update all packages: conda update --all (otherwise you get weird errors due to inconsistencies later)
create an environment for sage: conda create -n sage sage
enter your environment: source activate sage
The packages necessary to run sage are developed on the github pages of conda-forge. The actual sage package and many of its dependencies are maintained by Isuru Fernando (and a few volunteers).
There are still some issues with Conda. Not all tests pass and some things don't work:
There is likely not going to be a working package in the near future, see https://groups.google.com/d/msg/sage-devel/wyaV8x5qolI/jVS4DKBvCAAJ.
