Error while using Julia code : type - had no field -

Question

I am using Julia for my research. And this is what I am using : https://augustinas1.github.io/MomentClosure.jl/dev/tutorials/using_momentclosure/

I am going to run exactly same example code in the above website. But then, I got a error message like this :

using DiffEqBase.EnsembleAnalysis

means_SSA = timeseries_steps_mean(sol_SSA)
plot!(means_SSA, lw=2, labels=["SSA μ₁₀(t)" "SSA μ₀₁(t)"], linestyle=:dash,
      linecolor=[1 2], background_color_legend=nothing, legend=:bottomright)

type DiffEqArray has no field indepsym

I am using exactly same code, but this error occurs...How can I fix it???

I just copy and pasted the original code, but it does not work. I want to know how to run this example code.
