version 1.0

[Kelvyn88]

Yeah! Same error in Windows 10 with v1.0

[mgiugliano]

Same here on macOs with 1.0 (note: I have Anaconda installed. Before adding/installing PyPlot as a package on Julia, I have typed at Julia's prompt --> ENV["PYTHON"] = "/Users/XXX/anaconda/bin/python")

I am using Mac as well, did not type at Julia's prompt --> ENV["PYTHON"] = "/Users/XXX/anaconda/bin/python"). @mgiugliano

[ghost]

issue solved.

[mzaffalon]

Despite the PyCall warnings? Should they not be errors on Julia 1.0?

[Kelvyn88]

I just add the PyCall package and another one that I not remember in this moment. Another problem appears.

using Plots #runs well pyplot() #runs well

plot(1) #shows " left not defined"

new error

[stevengj]

The mimewritable issue was solved by #366. The LaTeXStrings errors were fixed by stevengj/LaTeXStrings.jl#24. The complaints about PyCall are a PyCall problem hat should be fixed by JuliaPy/PyCall.jl#522

In general, I would strongly recommend that most users use Julia 0.7 for the next month or so. There is no advantage to using Julia 1.0 over 0.7 — 1.0 is just 0.7 minus deprecations, so it turns warnings into errors. See also https://discourse.julialang.org/t/psa-use-julia-0-7-if-you-are-upgrading
