When I CSV.write a dataframe with a Float64 column, I get a "writeshortest not defined" error. The problem may be with the Parsers package.

julia> df = DataFrame( :a=>rand(Float64,2))
2×1 DataFrame
Row │ a
│ Float64
─────┼──────────
1 │ 0.823397
2 │ 0.226439
julia> f = open("test.csv","w")
IOStream()
julia> CSV.write(f,df)
ERROR: UndefVarError: writeshortest not defined
