What does the 'error emfile too many open files' error mean in a React Native development environment on macOS?

The 'error emfile too many open files' error indicates that your system has reached the limit of the number of files it can have open simultaneously. In a React Native context, this often arises from file watchers (like those used by `chokidar` or `watchman`) attempting to monitor a large number of files, exceeding the operating system's limit. It's common when dealing with monorepos or projects with extensive file structures.
