How to create julia projects

Create a Julia Project (with its own environment) From your project folder (in WSL or anywhere):

mkdir MyProject
cd MyProject
julia --project=.

Then inside the Julia REPL:

import Pkg
Pkg.activate(".")     # Activate this folder as a project
Pkg.add("JuMP")
Pkg.add("SDDP")
Pkg.add("Plots")

This will create two files in your folder:

Project.toml – lists dependencies

Manifest.toml – pins exact versions (optional to commit)

  1. Always Run Code Using the Project Environment In your Julia script (main.jl), start with:

# main.jl
using Pkg
Pkg.activate(@__DIR__)     # Activates the environment in this folder
Pkg.instantiate()          # Installs all packages if not already installed

using JuMP, SDDP, Plots

println("Everything is ready!")

  • This ensures your script can be run from anywhere and still use the local project environment.

  1. Run Your Script (Anywhere, Any Time) From WSL or terminal:

julia main.jl

Or, open VS Code in the folder and just hit Run – it’ll use the local environment.

  1. How to run current code:

julia --project=. any_file.jl
