I just started using julia-1.5.3 on my Linux machine (Pop!\_OS 20.10). I cloned [https://github.com/mcreel/Econometrics](https://github.com/mcreel/Econometrics) in order to add the package to Julia. Afterwards I did “using Econometrics” to use the package. I got three errors. this is the code.

```julia
julia> using Printf

julia> using Econometrics

Thanks for the interest. Please try this:

1. go to the directory where you cloned Econometrics, and start Julia
2. do `using Pkg; Pkg.activate(".")`
3. do `Pkg.instantiate()`
4. now do `using Econometrics`  
step 3 will take a while, as there are a number of packages that Econometrics relies upon.
