I was starting a React Native project on my MacBook Air but when running the command:
npx react-native start
I got an error that contained this line:
Error: EMFILE: too many open files, watch
I tried various ways to solve, until I found the suggestion to install the watchman utility using Homebrew.
I ran
brew install watchman
and that fixed the problem, because React Native internally was able to use watchman to watch files changes (used to provide hot reloading in the app to refresh it when a file is changed).
watchman looks like it’s more efficient than the built-in files watch system, since I got rid of that error.
One more thing! ⚠️ ✋
At the end of January I will organize the Web
Development
Bootcamp.
It's a 10-weeks long cohort online course where I will guide you to becoming a Web Developer.
It's not "just a course". It's a big event I organize once a year.
We'll start from zero, learn the fundamentals of Web Development, HTML CSS, JavaScript, Tailwind, Git, using the command line, VS Code, GitHub, Node.js, we'll then learn React, JSX, how to use PostgreSQL, Astro, Next.js, Prisma, deploying on Netlify/DigitalOcean/Fly/Vercel and much more!
At the end of the first 10 weeks you'll know how to create web sites and web applications and I'll unlock you the 2nd phase of the Bootcamp: you will get access to a large number of projects exclusive to the Bootcamp graduates, so you can follow my instructions to build things like private areas with authentication, clones of popular sites like Twitter YouTube Reddit, create e-commerce sites, and much much more.
Because once you got the fundamentals, you only learn by working on real, exciting projects.
