Error: ENOSPC: System limit for number of file watchers reached
The meaning of this error is that the number of files monitored by the system has reached the limit!!

Result: The command executed failed! Or throw a warning (such as executing a react-native start VSCode)

Solution:

Modify the number of system monitoring files

Ubuntu
```
sudo gedit /etc/sysctl.conf
```
Add a line at the bottom
```
fs.inotify.max_user_watches=524288
```
Then save and exit!
```
sudo sysctl -p
```
to check it

Then it is solved!
