Hello, David. I want to add component ng2-search-filter to my application. According to documentation ‘’ I can do it with command yarn add ng2-search-filter but this command causes an error:

yarn add ng2-search-filter>

yarn add v0.27.5

Exit code: 127

Command: sh

Arguments: -c typings install

Directory: /home/my_project/node_modules/ng2-search-filter


sh: typings: command not found info Visit for documentation about this command.

in local browser it behaves correctly but I can’t push to Heroku (it raises an error):

remote: Webpacker is installed

Could you advise me how can I add to my application ng2-search-filter, please. Thank you.
