Npm run serve Error - node.js

Question

I have a problem with running the command : npm run serve
to fix it i need to logout or reboot my Ubuntu 16.04
I have checked the running tasks and node is not running.
I have also uninstalled node and npm and installed again with NVM but i still have the problem .

The project is based on Vuejs (typescript)
The thing is that i can run "npm run dev" without problem on other projects that are normal Vuejs (not typescript)

Thanks for your time .

Answer 1

Running this code have solved my problem on ubuntu 16.04
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

Answer 2

Honestly, I don't know why this Error occurred!
But, once I tested it with sudo in terminal, it worked:
sudo npm run serve
or, for development:
sudo npm run dev

Answer 3

if you are getting problem to run command npm run serve than just delete your "node_modules" folder from your project and run command npm i or npm install which just run anyone command. This command will install your "node_modules" folder
again and with new and good dependencies now you are ready to use command
npm run serve
Thanks
