This package was deprecated like 3 years ago. The readme starts with:

```julia
This Package is in the Process of being Deprecated
Alternatives:
For automated finite difference discretization of symbolically-defined PDEs, see MethodOfLines.jl.
For MatrixFreeOperators, and other non-derivative operators, see SciMLOperators.jl.
For VecJacOperators and JacVecOperators, see SparseDiffTools.jl.

```

I would be very surprised if you could install it on the lastest Julia.
