Error creating new project in ionic 4.1.2

Ionic Framework
1

Suddenly … I get an error whenever creating a new project. Here is the error when i run the verbose flag:

[ERROR] An error occurred while running subprocess npm.

    npm i exited with exit code 1.
    
    Re-running this command with the --verbose flag may provide more 
    information.

ionic:cli-framework:utils:process onBeforeExit handler: process.exit received +0ms
ionic:cli-framework:utils:process onBeforeExit handler: running 1 queued functions +0ms
ionic:cli-framework:utils:process onBeforeExit handler: exiting (exit code 1) +20ms

My ionic info is:
Ionic:

ionic (Ionic CLI) : 4.1.2

System:

NodeJS : v8.11.3
npm : 6.4.1
OS : macOS High Sierra

It was all working fine a few days ago … I tried uninstalling and reinstalling ionic but nothing changes. Any help would be really appreciated

J’avais le meme genre de probleme mais avec cordova. J’ai du faire une installation global.
Essayez sudo npm install -g ionic cordova

No, don’t run npm with elevated privileges, or it will become very hard to clean up afterwards. Instead, install nvm.
