Cant install in julia version 1.6.0

[ravitejapavuluri]

When I tried to install with these set of lines:
using Pkg
Pkg.add(PackageSpec(url="https://github.com/plotly/DashBase.jl.git"))
Pkg.add(PackageSpec(url="https://github.com/plotly/dash-html-components.git", rev="master"))
Pkg.add(PackageSpec(url="https://github.com/plotly/dash-core-components.git", rev="master"))
Pkg.add(PackageSpec(url="https://github.com/plotly/dash-table.git", rev="master"))
Pkg.add(PackageSpec(url="https://github.com/plotly/Dash.jl.git", rev="dev"))

it gives an error:
Unsatisfiable requirements detected for package DashHtmlComponents [1b08a953]:
DashHtmlComponents [1b08a953] log:

Hi!
It can be done much easier - Pkg.add("Dash")

What you wrote is installing a development version. This description is outdated, thanks for the reminder - I will rewrite it. In any case, at the moment the development version corresponds to the latest release
