Error when loading Distributions package for parallel computing

General Usage

I’m using parallel computing for some parts of my Julia code and for that, I need to load 2 packages: LinearAlgebra and Distributions. Concerning LinearAlgebra I run the following code and it works:

using Distributed
using LinearAlgebra
using Distributions
addprocs(1)
@everywhere using LinearAlgebra

But when I try @everywhere using Distributions I have the following error:

On worker 2:
ArgumentError: Package Distributions not found in current path:
- Run `import Pkg; Pkg.add("Distributions")` to install the Distributions package.

I have the same error with LightGraphs package: @everywhere using LightGraphs doesn’t work.
What am I doing wrong? I’m using JuliaPro v. 1.1 with Julia 1.1.

This might be related to running JuliaPro alongside standard Julia.
