Hello, I wanted to load CSV in the environment but I got this error:

```julia

```

How can I solve it?  
Thanks

PS: none of the libraries are in the path: another of the packages that I run routinely gave me:

```julia
julia> using DataFrames
ERROR: ArgumentError: Package DataFrames not found in current path:
- Run `import Pkg; Pkg.add("DataFrames")` to install the DataFrames package.

Stacktrace:
 [1] require(::Module, ::Symbol) at ./loading.jl:893

```

I reinstalled Julia core and rebuilt the packages. That fixed the error…
