Answer 1

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.
