Conda.add("scikit-learn") works in OS X but not in Linux during travis build

[ppalmes]

Conda.add("scikit-learn") in Linux prompts this message below during travis build: Would you like to use a personal library instead? (y/n)

OS X has no issues and just installs scikit-learn without this prompt.

Is there any option in Conda.add() to say yes in the "use personal library" prompt?

I found out this is not conda.jl issue but in rcall.jl. closing this issue.
