Ionic4 4.2.1 : Linux can't run "ionic serve" without an error

I am struggling in this error when I try the first run on an Ionic4 project. when I try “ionic serve” I’m getting this error:

ng run app:serve --host=0.0.0.0 --port=8100
 [ERROR] ng has unexpectedly closed (exit code 1).
 The Ionic CLI will exit. Please check any output above for error details.

I didn’t change anything in the project, just created and tried to run. I tried in Windows and it works like a charm, but I can’t make it run on Linux. I tried other computers and I am getting the same error, what makes me believe there is a bug in ionic cli when running it in linux OR I should make some changes in linux to make it run.

When I run “ionic serve --verbose” I get this error “detail”:

This my Ionic Info:

Ionic:

   ionic (Ionic CLI)             : 4.2.1 (/usr/local/lib/node_modules/ionic)
   Ionic Framework               : @ionic/angular 4.0.0-beta.13
   @angular-devkit/build-angular : 0.8.5
   @angular-devkit/schematics    : 0.8.5
   @angular/cli                  : 6.2.5
   @ionic/angular-toolkit        : 1.0.0

Cordova:

   cordova (Cordova CLI) : not installed
   Cordova Platforms     : none
   Cordova Plugins       : no whitelisted plugins (0 plugins total)

System:

   NodeJS : v10.12.0 (/snap/node/1149/bin/node)
   npm    : not installed
   OS     : Linux 4.15

Although it is saying that npm and Cordova are not installed, they are installed, at least if I run “npm --version” it returns to me with “6.4.1” and cordova “8.1.2 (cordova-lib@8.1.1)”.

Ionic3 projects is running smoothly.

@davidrock What happens if you run npx ng serve?
