Trying to `add` DifferentialEquations with DynamicalSystems installed results in a package requirements error in 0.6.2:

```julia
julia> Pkg.add("DifferentialEquations")
ERROR: resolve is unable to satisfy package requirements.
  The problem was detected when trying to find a feasible version
  for package DynamicalSystemsBase.
  However, this only means that package DynamicalSystemsBase is involved in an
  unsatisfiable or difficult dependency relation, and the root of
  the problem may be elsewhere.
  (you may try increasing the value of the JULIA_PKGRESOLVE_ACCURACY
   environment variable)

If I `rm` DynamicalSystems and try to `add` DifferentialEquations, Julia says that offending package is DiffEqUncertainty.

(what’s the proper etiquette for these things, first posting here or directly opening an issue in GitHub?)

The package resolver just isn’t able to find out what the problem package is, but it’s not one of those two. What’s your `Pkg.status()`? Maybe I will see something, but this can be a really hard to problem to resolve. My best guess is that something is upper bounding Optim.jl or NLsolve.jl due to its most recent changes, and those upper bounds are affecting DifferentialEquations.jl

I don’t see it. Honestly, the only way I know to debug this is to remove `.julia/v0.6` and add packages back one-by-one and see what downgrades it.

Maybe this helps: I just got a similar problem when installing `DifferentialEquations` (in my case it complained about `DiffEqDevTools`). Increasing `JULIA_PKGRESOLVE_ACCURACY` to 3 (i.e. `ENV["JULIA_PKGRESOLVE_ACCURACY"] = 3`) solved the issue.

I’m having the same problem, though the “offending” package is `DiffEqUncertainty`. This problem occurred on my personal MacOS environment and a corporate Windows machine. Strangely, @AleMorales suggestion fixed the issue on Windows but not MacOS.

Try assigning a higher value to `ENV["JULIA_PKGRESOLVE_ACCURACY"]`. Today I had to use a value of 5 to resolve `Pkg.add("Coverage")`, I am not sure what is happening with the the dependencies lately, I never had this problem until 10 days ago. I think that the problem is going to depend on which packages (and which versions) you have installed on each machine.

DiffEq added a bunch of upper bounds so that way the old syntax `(t,u,du)` would not mix with packages on the new syntax `(du,u,p,t)` since that would just be broken. However, it looks like that resolver is no able to easily find out that it can “jump up” to the next major version on all of these packages simultaneously. FWIW, fresh installations where you wipe `.julia/v0.6` seem to work, though that’s quite a nuclear option.

Silly me. On seeign this topic title I though that @amrods was desiring to add some differential equations together.

Since removing the packages and re-adding DiffEq was working for everyone, I decided that the least intrusive approach at this point was to simply remove the upper bounds.

[https://github.com/JuliaLang/METADATA.jl/pull/13385](https://github.com/JuliaLang/METADATA.jl/pull/13385)

In theory you can get incompatible versions of packages, but in practice without upper bounds the resolver updates you to the latest versions and so this tends to work (while we know that the situation with the upper bounds doesn’t).

If you have any more issues, please let me know.

I am trying to install DifferentialEquations for my fresh install of JuliaPro, but I get the following error:

ERROR: Unsatisfiable requirements detected for package NLSolversBase:  
(and many lines of info)

edit: I noticed that this error is related with NLsolve package, which is currently not listed after running Pkg.status(). Trying to add this package gives similar error.

I hope there is some easy way to work through it, as I wanted just to test the speed of Julia as compared to Matlab, but on JuliaBox solving speed was rather big…

Why not use a regular Julia installation? I think that the issue is because JuliaPro is fixing Optim.jl to an older version, which fixes NLSolversBase to an older version and makes it all incompatible.

You don’t need JuliaPro for the IDE. You just install Atom and install the uber-juno plugin.

On v0.6 we have no control over what packages they pin which can break the installation. On v0.7 this is fixed by Pkg3 environments.
