After downloading Pkg again, there is no change

```julia
using LPVSpectral, Plots
a=convert(Vector{Float64},rand(20))
λ = 0.02 # Regularization parameter
λs = 1 # Regularization parameter group-lasso
normal = true # Use normalized basis functions
Nv = 50 # Number of basis functions
 x = sort(10rand(20))
 v = range(0, stop=1, length=20) 
se = ls_spectral_lpv(a,X,V,w_test,Nv; λ = λ, normalize = normal)

```

It’s still reporting an error.  
Why?thanks!

first you should [make it easier to help you](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you/14757).  
Its hard to get what the actual issue is:

How do you “download” the package:

- `]pkg up` ?
- `cd $PATH_TO_REPO ;git pull` and then doing a `]dev "PATH_TO_REPO"` in julia?
