Pkg.add("Quandl") ERROR: resolve is unable to satisfy package requirements.

[boomalgo]

Hello.

I am new user of Quandl.Ji and facing this issue.

julia> Pkg.add("Quandl")
ERROR: resolve is unable to satisfy package requirements.
The problem was detected when trying to find a feasible version
for package DataFrames.
However, this only means that package DataFrames is involved in an
unsatisfiable or difficult dependency relation, and the root of
the problem may be elsewhere.

Kindly look into issue.
