okta laravel vue development getting save error from ubuntu terminal

Question

I am doing a tutorial using laravel and vuew and okta. From here but when I run the command

yarn add --save vue-router axios @okta/okta-vue

It gives me the error

Usage: yarn [options]

yarn: error: no such option: --save

UPDATE:

install

npm install --save axios vue-axios
yarn add vue-router axios @okta/okta-vue

Still did not solve the issue

Answer 1

maybe you use

npm add --save vue-router axios kta/okta-vue
npm run serve

it works！
