Installation

General Instructions

Two ways of using Spectra: [1] with using a cloud-computing approach and [2] with installing everything on your computer.

[1] JuliaBox (https://www.juliabox.org/) allows you to run Julia in your browser. You still need to add Spectra. To do so, run a notebook, and in the first instance, type

```
Using Pkg
Pkg.add("Spectra")
```

Everything should install without trouble. Requirements in Spectra are extensive and will provide you all the packages needed by Spectra's functions and examples.

[2] You can download the current version of Julia and follow the installation instruction here: http://julialang.org/downloads/ . Then, type ] in the Julia REPL shell. You should see Pkg> instead of julia> on the prompt. If yes, do

```julia-repl
Pkg> add Spectra
```

Notes on gcvspline for v0.4.1 and higher

Installing the gcvspline Python library is optional but gives access to the GCV algorithms in the smooth() and baseline() functions. Install as

```julia-repl
 julia> using PyCall
 julia> pyimport_conda("pip", "pip")
 julia> run(`$(PyCall.python) -m pip install $("gcvspline")`)
 ```

Prior to v0.4.1:

Please update to version v0.4.1 :)

Error messages?

If you see various errors messages when trying to install Spectra or after a Pkg.update() command, please see the Tips section!
