Ошибка: не удалось найти '@ ionic / angular / css / display. css'

Question

Я переношу свой проект ioni c с версии 4 на версию 5. Для этого я изначально установил последнюю версию ioni c 4 с этой командой

npm install @ionic/angular@^4.0.0

Но теперь это так. выдаёт мне эту ошибку

ERROR in ./src/global.scss (./node_modules/@angular-devkit/build-angular/src/angular-cli-files/plugins/raw-css-loader.js!./node_modules/postcss-loader/src??embedded!./node_modules/sass-loader/lib/loader.js??ref--15-3!./src/global.scss)
[ng] Module build failed (from ./node_modules/postcss-loader/src/index.js):

Вот мой глобал.s css
