Error installing sage, with R 3.4.3

[James Barry]

Hello,

today I tried installing sage, I am running Ubuntu 17.10 and already have anaconda installed, though I have not installed R before.

The sage installation worked well except for the R part, see attached log file. I have tried opening sage and it works.

What to do?

Best regards,

James

If you don't specifically need R functionality,

just use the version of SageMath you obtained,

you should be fine.

It might be anaconda that breaks the installation somehow. Namely, Ubuntu 17 does not come with libiconv at all.

Or perhaps it's some other stale stuff.

Could you try temporarily uninstall anaconda and try making Sage again?

That could work. Dumb question, but should I be able to launch sage from anywhere, ie on the command line? It seems like I have to navigate to the sage folder first...

Thanks for the tip. Yes I have actually had this problem before with libiconv and anaconda.

Would you recommend removing anaconda completely and not installing it again?

You could once and for all navigate to the sage folder and run

the following in a  terminal:

    sudo ln -sf `pwd`/sage /usr/local/bin

after which you should be able to start Sage from anywhere by

just running

    sage
