Cannot find module 'typescript' | Ionic 4

I pull the ionic 4 code from git to my pc and tried to run it and it shows "Cannot find module 'typescript'" even I installed it already by using

npm install typescript

and also installed globally by

npm install -g typescript

Error log:

[ng] Cannot find module 'typescript'

[ERROR] ng has unexpectedly closed (exit code 1).

Additionally, i also tried

npm install @ionic/app-scripts@latest --save-dev

this command, but it doesn't work.

Can anyone help me with this issue?
