    Error: Lock found, but no process with PID 43470 seems to be running. [ng] (If you are sure no ngcc process is running then you should delete the lock-file at yourproject/node_modules/@angular/compiler-cli/ngcc/ngcc_lock_file.)

    rm yourproject/node_modules/@angular/compiler-cli/ngcc/ngcc_lock_file

    et voila.

    I don't know why but using sudo was the only way to solve this on my ubuntu machine! I just needed to run the command using sudo:

    sudo ionic serve

    Run the below command, being in root directory of Ionic project:

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

    Then you can try Ionic serve or Ionic s.

    You must kill the NodeJs service I believe it's a bug

    Maybe there is an issue in your hosts file. Make sure your ::1 should enable or not commented.
