Unsatisfiable requirement (Nemo SIUnit Images TexExtensions)

#1

I installed julia 1.1.0 (linux binary 64bits) together with a few packages (among which Images 0.17.2). I am now trying to install Nemo and I get the following error.

How can I install these packages?

It seems that the problem comes from the TexExtensions package.

That package saw no commit for two years and my julia installation is less than two months old. I hesitate to upgrade all the packages since everything is working fine at the moment. Maybe I can try to update only Images?

May I suggest making your ~/.julia/environments/v1.1 directory a git repo—that way you have version control for your installed packages and can roll back to a working state if things don’t go well. Unless you do pkg> gc the old versions will all still be there so rollback is trivial and doesn’t even involve reinstalling anything.
