Not able to install package "string-extra" for elm version 0.18

[Srinivasan Ragothaman]

Hi,
I am getting below error while installing the package "string-extra" in elm version: 0.18.0

D:\MyWS\ElmWS\myelm>elm-package install elm-community/string-extra
To install elm-community/string-extra I would like to add the following
dependency to elm-package.json:

"elm-community/string-extra": "1.3.1 <= v < 2.0.0"

May I add that to elm-package.json for you? [Y/n] y

Error: I cannot find a set of packages that works with your constraints.

--> There are no versions of NoRedInk/elm-string-extra that work with Elm
0.18.0. Maybe the maintainer has not updated it yet.

after couple of times tried with same command. Installed successfully.
