Julia does not update its packages

I installed DifferentialEquations by using:

Pkg.add("DifferentialEquations")

Then I used the below line to check the version:

Pkg.status("DifferentialEquations")

It returns 1.0.0 while, it must be 4.0.0.

I tried Pkg.update() or Pkg.update("DifferentialEquations). However, the version is still 1.0.0 and re-installing Julia did not help neither.

What can be done to update the DifferentialEqautions package?

The version of Julia is 0.6.2.

Edit

This time I not only uninstalled Julia, but I also deleted its folder in appdata. After installing Julia again and adding the package, now it is up to date.

What version julia are you running? This could be limiting the version of DifferentialEquations. - Colin T Bowers
The version of Julia is 0.62. - MOON
When you run Pkg.status, does it say that any of your package versions are pinned (on any package?)? - Chris Rackauckas

Have you tried :

Pkg.pin("DifferentialEquations",v"4.0.0")

You can force Pkg to find a solution by giving an explicit version.

For example, going from version 5 to version 6 of the DifferentialEquations package:

(TestProject) pkg> status
    Status `/tmp/TestProject/Project.toml`
  [0c46a032] DifferentialEquations v5.0.0

(TestProject) pkg> add [email protected]
 Resolving package versions...
  Updating `/tmp/TestProject/Project.toml`
  [0c46a032] ↑ DifferentialEquations v5.0.0 ⇒ v6.0.0
  Updating `/tmp/TestProject/Manifest.toml`
  [1520ce14] - AbstractTrees v0.2.1
  [79e6a3ab] - Adapt v1.0.0
  [4fba245c] ↓ ArrayInterface v2.3.1 ⇒ v0.1.1
  [9e28174c] - BinDeps v1.0.0
...

(TestProject) pkg> status
    Status `/tmp/TestProject/Project.toml`
  [0c46a032] DifferentialEquations v6.0.0

The equivalent API syntax:

julia> import Pkg
julia> Pkg.add(Pkg.PackageSpec(; name="DifferentialEquations", version=v"6.0.0"))
