Have you tried running the example from the documentation here?

Are you sure you are on the latest version? You might be using an old version of the package which had a different API? (Indeed looking at the 1.0 documentation it includes the `RadialBasis(::Any, ::Any, ::Any, ::Function, ::Int64)` signature given in your error message)

Hallo  
I am using the Julia 1.0.5 ![image](https://global.discourse-cdn.com/julialang/original/3X/e/a/ea074c5fc3d6914261725b66451c3e16a9c5b93c.png)  
guess this is the latest version.

Sorry I meant version of the `Surrogates` package, not version of Julia - but this is a good point, Julia 1.0.5 is very much not the latest, the current Julia release is 1.6, and many packages do not support v1.0.5 any longer. You should be using 1.6
