Hi, I am trying to use add some packages but the following error appears:

```julia
(v1.0) pkg> add Yao
 Resolving package versions...
ERROR: Unsatisfiable requirements detected for package ASTInterpreter2 [e6d88f4b]:

```

I tried adding other packages such as Flux and Makie but the same error arise. Any idea what could be the reason?

Try issuing `pkg> update` before trying to add the new package.

Had the same issue after updating Atom and Julia and updating packages worked for me.  
In Atom I ran _Pkg.update()_ and everything went back to normal.  
Thanks
