Hey all,  
As in my daily routine I was about to work with dataframes but today the package Dataframes.jl is not working. I have of course installed the package some time ago, but today I had to reinstall it after I got this error:

> ERROR: ArgumentError: Package Dataframes not found in current path

So I added it with `import Pkg; Pkg.add("Dataframes")` but instead I got a second error:

> ERROR: The following package names could not be resolved:
> 
> - Dataframes (not found in project, manifest or registry)

I looked online before writing this post and several people (from 2018-2021) suggested that with the new Julia version 1.0 all packages required to have a new structure (with Project.toml etc.) and those which were not updated could not be used. However, I am not sure if this is the same problem of today.

Anybody who can help? 🙂

“Dataframes” → isn’t it DataFrames? (Capital F)
