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](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,

```julia
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.
