General Usage

Hi ,
I need to install packages from a list.
I was wondering if julia has an a command to install from list.
like python’s "pip install -r requirements.txt " ?

Thanks.

Yes.

You can use Pkg to install multiple packages (https://github.com/JuliaLang/julia/issues/19591). For instance: Pkg.add(["Combinatorics", "TaylorSeries"]).

If your list sits in a text file, you can just load it and pass it to Pkg.add.

I don’t know of any built in command like this. But writing a little script for this seems simple and straightforward: read the file and use Pkg.add(pkgname) to add them one after another.

Of course, the Manifest.toml is made for this purpose or actually Project.toml depending how you will want to use the list.

@ilango3 The We can create a requirements.txt Python equivalent by creating a julia script
packages.jl

The contents of the packages.jl will be,

using Pkg

dependencies = [
    "IJulia",
    "Genie"
]

Pkg.add(dependencies)

We can add more dependencies in this list.
This can be executable with the command julia packages.jl

note for most purposes the julia equiv of a requirements.txt is a Project.toml
but you can’t write one by hand.
