Yarn List of Deprecated Dependencies

[lalaithan]

Upon installing dependencies with yarn, I got a list of deprecated dependencies. Should these be ignored?

Thanks for checking out my theme.

I tried to replicate your output by getting a fresh clone of the repo and install the dependencies myself.
This is the output I got: no warning or mentions of deprecated dependencies.

❯ yarn
yarn install v1.22.0
warning package-lock.json found. Your project contains lock files generated by tools other than Yarn. It is advised not to mix package managers in order to avoid resolution inconsistencies caused by unsynchronized lock files. To clear this warning, remove package-lock.json.

warning Your current version of Yarn is out of date. The latest version is "1.22.4", while you're on "1.22.0".
info To upgrade, run the following command:
$ curl --compressed -o- -L https://yarnpkg.com/install.sh | bash

Also Dependabot has not mentioned any security problems in the Security tab in Github.

I assume you can ignore it.
