Compose cannot remove

[Nicolaikimbrer]

Hi all

I tried to install a language package, but after this i get alot off issues and i do not want the language package. How can i remove these requests? 

When i enter command: composer remove fd/language-zh_hant_hk

I get: 

fd/language-zh_hant_hk is not required in your composer.json and has not been removed
Package "fd/language-zh_hant_hk" listed for update is not installed. Ignoring.
Loading composer repositories with package information

Could not fetch https://api.github.com/repos/4dhk/Magento2Language-zh_Hant_HK, please create a GitHub OAuth token to go over the API rate limit
Head to https://github.com/settings/tokens/new?scopes=repo&description=Composer+2018-03-12+2226
to retrieve a token. It will be stored in "/home/kimbrer_com/.composer/auth.json" for future use by Composer.

If you wanted to remove/uninstall this language pack - run below command :

php bin/magento i18n:uninstall fd/language-zh_hant_hk

After that clean and flush cache by running below commands

php bin/magento cache:clean

php bin/magento cache:flush
