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:

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

```

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

```julia
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.

Thank you 🙂 I know that most of the times the same questions are asked more than once… I try to find similar questions on Google but I’m not able to find them. You guys here are always able to point directly to similar questions 🙂 Will try your suggestions and see if I can solve the problem 🙂
