What is the correct way to use `PackageCompiler` in 1.1?
I naively tried:
```julia
using PackageCompiler
compile_incremental(:Plots, force=false)
```
And it keeps throwing dependency errors, like: “LoadError: … Package … is required, but does not seem to be installed”. First about `VisualRegressionTests`, then about `UnicodePlots` and `StatsPlots` and then, having installed these, about `Images`. Knowing that the dependency tree can be arbitrarily deep, I gave up at this point.
Am I doing anything wrong? Any idea why it doesn’t find these dependencies?
There is an [issue](https://github.com/JuliaLang/PackageCompiler.jl/issues/239) in `PackageCompiler` about this, which recommends using the now-defunct `notoml` branch, but that’s basically it.
I also tried it with the `GR` package and there I get some error about “Task cannot be serialized”. Might `PackageCompiler` be defunct in 1.1?
I’m on Windows.

Try the master branch with `pkg> dev`:

Better to use/recommend `add PackageCompiler#master`.

No, there’s a bug in PackageCompiler which means that you get that serialization error unless you `dev` (yes, this is very weird, and no, I don’t know why it happens).

Thanks a lot! This fixes the serialization errors!
I’m still getting the various dependency errors precompiling `Plots`, though. Anyone else here seeing these?

1. Yes, same dependencies errors using Julia v1.1.1 ([julialang.org](http://julialang.org) official binaries) on Linux. Also tried `pkg> instantiate`, but it didn’t find any missing dependencies.
2. Also, if somebody is using Julia binaries installed from Linux distribution’s repositories (in this case Arch Linux), there is error building Arpack while doing `compile_incremental(:Plots, force=false)`, also when tried to build manually, but still:
```julia
(v1.1) pkg> build Arpack
Building Arpack → `~/.julia/packages/Arpack/cu5By/deps/build.log`
┌ Error: Error building `Arpack`:

```
But error is not occurring using official Julia binaries from [julialang.org](http://julialang.org)! Maybe different GCC versions used to compile Julia caused that (could be related: [Installation error when Julia is built from source · Issue #5 · JuliaLinearAlgebra/Arpack.jl · GitHub](https://github.com/JuliaLinearAlgebra/Arpack.jl/issues/5)).

@pfitzseb, I am using `add PackageCompiler@master` and no serialization errors, maybe this could be the cause:
“The package `dev` command works similar to `add` but instead of locking the package to the state it was when you added it, the environment using the package will continuously use the latests changes to the package.” [My New Workflow with Julia 1.0.
