I’m trying to find out what is holding back `DataStructures` package.  
Installed version is `v0.17.20`, latest version is `0.18.4`.

Attempting to explicitly add the latest version of `DataStructures` reveals a seemingly weird incompatibility with `ReverseDiffSparse`, `JuMP` and `Compat`.

It seems `ReverseDiffSparse` is used by older versions of `JuMP`, but is not a dependency of the current and installed version (`JuMP` `0.21.3`), and `ReverseDiffSparse` does not appear in my `Project.toml` or `Manifest.toml` files.

```julia
(v1.5) pkg> add DataStructures@0.18.4

I may be missing something here, but which `Project.toml` or `Manifest.toml` are you talking about, the `(v1.5) pkg>` give me the impression you are not inside a specific environment, is it correct?

Unfortunately the log seems specially hard to understand (I often can pinpoint the source of the problem by it). It seems kinda of cyclical? You cannot update `DataStructures` because `JuMP` and `JuMP` cannot update because `DataStructures`. I would recommend `rm`ing all packages involved and installing them again starting by `DataStructures@0.18.4` this will either work or give a better understanding of where the problem pops up.

Yeah, I just meant the `Project.toml` and `Manifest.toml` in the default environment at `~.julia/environments/v1.5`

Here’s what happens after removing `DataStructures` and `JuMP`.

After `up`, `DataStructures` (as a dependency) is upgraded to `0.18.4`:

```julia
(v1.5) pkg> up
   Updating registry at `...\.julia\registries\General`
No Changes to `...\.julia\environments\v1.5\Project.toml`
Updating `...\.julia\environments\v1.5\Manifest.toml`
  [864edb3b] ↑ DataStructures v0.17.20 ⇒ v0.18.4

```

Now `add` back `DataStructures` and `JuMP`:

```julia
(v1.5) pkg> add DataStructures
  Resolving package versions...
No Changes to `...\.julia\environments\v1.5\Project.toml`
No Changes to `...\.julia\environments\v1.5\Manifest.toml`

(v1.5) pkg> add JuMP
  Resolving package versions...
Updating `...\.julia\environments\v1.5\Project.toml`
  [864edb3b] ↓ DataStructures v0.18.4 ⇒ v0.17.20
  [4076af6c] + JuMP v0.21.3
Updating `...\.julia\environments\v1.5\Manifest.toml`
  [49dc2e85] + Calculus v0.5.1
  [864edb3b] ↓ DataStructures v0.18.4 ⇒ v0.17.20
  [4076af6c] + JuMP v0.21.3

```

Adding `JuMP` seems to downgrade `DataStructures`.

[Yes, it seems right.](https://github.com/jump-dev/JuMP.jl/blob/e2fd3ebd9e3f5e6913ba461c0bc54e5cc92f061e/Project.toml#L20)

Maybe you should ping JuMP developers about it? Open an issue, or maybe ask if it will be changed in the next update using [this chat](https://gitter.im/JuliaOpt/JuMP-dev).

What happens if you do this:

```julia

```

And then, can you also try this?

```julia

This should be fixed by making a new release of JuMP. I’ve opened an issue here: [https://github.com/jump-dev/JuMP.jl/issues/2326](https://github.com/jump-dev/JuMP.jl/issues/2326)

Yes upgrading to `JuMP#master` fixes the issue.

This is what confused me.  
I looked at `Project.toml` of `JuMP` online (which is of course master), and allows `DataStructures@0.18`  
I should have been looking at `Project.toml` from `JuMP@0.21.3`.

Thanks all for your help!

You could also do `] add JuMP DataStructures@0.17` while we sort out a new release.
