That’s a very old version of Distributions. Grab something released within the last few years and you should be good. Something v0.25.x is preferred. I’d be curious to know why this was help back.

TuringTutorials isn’t a registered package, it’s just the tutorials repository. [GitHub - TuringLang/TuringTutorials: Educational material and tutorials for the Turing language](https://github.com/TuringLang/TuringTutorials) . Is there a reason you need it?

inatalling julia through these binaries has no error…it installed successfully, however when i run the following code  
using Turing  
using DifferentialEquations  
using OrdinaryDiffEq, DiffEqParamEstim, JuMP, NLopt, Plots

# Load StatsPlots for visualizations and diagnostics.

using StatsPlots

using LinearAlgebra  
using DiffEqParamEstim  
using DiffEqBayes  
using Optim

# Set a seed for reproducibility.

using Random  
Random.seed!(14);

following is the error
