I’m trying to update Flux to v0.10.0 but my Julia is stuck at v"0.8.3". Typing `]update Flux` does not change it.

Before that, my Flux was in v0.10.0 but I tried model zoo [https://github.com/FluxML/model-zoo](https://github.com/FluxML/model-zoo) and ran  
`using Pkg; Pkg.activate("."); Pkg.instantiate()`  
which reverted Flux to v0.8.3

I looked into my `\.julia\environments\v1.3\Manifest.toml` and sure enough, there Flux is given as v0.8.3. How do I make it update?

I solved it by first deleting the old entry in the `Manifest.toml`

```julia
using Pkg
Pkg.rm("Flux")
Pkg.rm("CUDAdrv") # otherwise it has compatibility problems

```

Then using  
`Pkg.add(Pkg.PackageSpec(name="Flux", version="0.10.0"))`
