can this be true?:

MethodError: no method matching sort!(::Dict{Int64,String})

that seems to be basic thing, am I doing something wrong?

Regards,

Alar Aints,

`Dict`s are unordered, so you cannot sort them.  
[OrderedDict](https://github.com/JuliaCollections/OrderedCollections.jl)s are ordered, so you can sort them.

```julia
julia> using OrderedCollections

julia> d = OrderedDict(1 => :a, 4 => :b, 3 => :c, 2 => :d)
OrderedDict{Int64,Symbol} with 4 entries:
  1 => :a
  4 => :b
  3 => :c
  2 => :d

julia> sort!(d)
OrderedDict{Int64,Symbol} with 4 entries:
  1 => :a
  2 => :d
  3 => :c
  4 => :b

julia> d
OrderedDict{Int64,Symbol} with 4 entries:
  1 => :a
  2 => :d
  3 => :c
  4 => :b

```

Thanks, so how do I get it?  
I typed:  
using Pkg  
Pkg.add(“OrderedCollections.jl”)  
I got:  
**julia\>** Pkg.add(“OrderedCollections.jl”)

**Cloning** default registries into `~/.julia`

**Cloning** registry from “[GitHub - JuliaRegistries/General: The official registry of general Julia packages](https://github.com/JuliaRegistries/General.git)”

**Added** registry `General` to `~/.julia/registries/General`

**ERROR:** The following package names could not be resolved:

- OrderedCollections.jl (not found in project, manifest or registry)
