在新的 vue 项目上运行 npm run serve 时出错

Question

I made this:

vue create myfirstapp 
atom (for open my editor)
cd myfirst app
npm run serve 

and I get this

> myfirstapp@0.1.0 serve /home/paolinsky/Documentos/vueBasico/fazt/myfirstapp
> vue-cli-service serve

This always happen in all my vue projects, included the new ones.

My versions are: npm: 6.13.4 node: v13.3.0

I ran into this same problem recently. I solved it like this:

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

cat /proc/sys/fs/inotify/max_user_watches

fs.inotify.max_user_watches=524288
