Yarn error "no such option" with --dev flag

ignite-ir-boilerplate was not able to be installed. Is it a valid NPM module?

Command failed: yarn add ignite-ir-boilerplate --dev
Usage: yarn [options]

yarn: error: no such option: --dev
Solution

  • You probably installed yarn using this: $ apt install cmdtest

    Use this instead: $ npm install --global yarn
