Hi,

[Edit: It seems that I just needed to do a `pkg> update` prior to adding the package. Now off to read about why …]

I’m new to Julia and am having trouble installing Gadfly, specifically this happens when I try to add the package:

```julia
(v1.1) pkg> add Gadfly

P.S. I tried under Ubuntu in a VMWare session and I get a different compatibility issue:

@klaff even after doing `update` when in `Pkg` I can’t add `Gadfly`. Do you know what is the issue?

This is the output I get

I have `DataArrays` installed already.

Despite my comment above I didn’t do much more research, so I don’t know how to figure out where the conflicting requirements are coming from.

[DataArrays.jl](https://github.com/JuliaStats/DataArrays.jl) is a deprecated package, and isn’t a requirement of the current version of Gadfly: [https://github.com/GiovineItalia/Gadfly.jl/blob/master/Project.toml](https://github.com/GiovineItalia/Gadfly.jl/blob/master/Project.toml).  
So try removing DataArrays.

Thanks, I’ve removed `DataArrays` but still I cannot add `Gadfly`. I did `update` after removing `DataArrays`, but I still get the same error.

Does `add Gadfly#master` work?  
If not, can you list your Pkg status.

I had a similar problem installing StatsBase and it was due to Distributions v0.19 package.

Can you try uninstalling Distributions and then install Gadfly? If this does not work then also uninstall StatsBase and try.

</div>

or `add StatsBase@0.29`

The explanation (as I understand it) is that if you have a package B (e.g. `StatsBase`) installed independently in your environment that package A (e.g. `Gadfly`) depends on, then package B in your environment needs to match package A’s [Project.toml](https://github.com/GiovineItalia/Gadfly.jl/blob/master/Project.toml). @kristoffer.carlsson might want to elaborate.

Reading the posts above, you need to downgrade 2 packages in your environment (Distributions and StatsBase) to the same versions as in Gadfly’s [Project.toml](https://github.com/GiovineItalia/Gadfly.jl/blob/master/Project.toml). Try `add Distributions@0.18` first.

If that doesn’t work, maybe edit the Project.toml file in your v1.1 environment, so that it contains the needed [compats] for Distributions and StatsBase, and then `instantiate` the Project.toml in a (clean) v1.1 folder. See [Pkg docs](https://julialang.github.io/Pkg.jl/v1/compatibility/) for more info.

@Mattriks Perfect! Installing `Distributions@0.18` and `add StatsBase@0.29` works like a charm. Now `add Gadfly` runs ok. Thanks!

I tried all of the above recommendations and Gadfly still has unsatisfiable requirements detected. What changed since 2019? Thanks.

Gadfly is my favorite 2D plotting package however, there is something odd about Gadfly’s interaction with the package manager. I haven’t been able to figure out why. However, some of the other comments sound familiar to me. The interaction with DataArrays being one.

If I don’t pin my version of Gadfly to the latest (v1.2.1) then Gadfly is sometimes (~30% of the time) downgraded by the package manager to a 2 year old version (0.8 ish) which installs a non-compiling version of DataArrays. Everything goes downhill from there. Before I started pinning Gadfly to the latest revision, I’d dread `] update` as I’d never know what was going to happen once the cascade of downgrades started.
