Understanding the Issue
Before we begin, it’s essential to grasp the fundamental concepts behind npm and Expo. npm (Node Package Manager) is the package installer for Node.js, responsible for managing dependencies and installing packages. Expo, on the other hand, is a popular framework for building cross-platform React Native applications.
The “npm install failed” error can occur due to various reasons, including:
- Corrupted or outdated package versions
- Incompatible dependencies
- Permission issues
- Node.js or npm version conflicts
- System configuration problems
Step 1: Verify Node.js and npm Versions
Let’s start by ensuring you’re running the latest versions of Node.js and npm. Open your terminal and run the following commands:
node -v npm -v
Take note of the versions displayed. If you’re not running the latest versions, update Node.js and npm using the following command:
npm install -g n n latest
Step 2: Check Expo CLI Version
Next, verify the Expo CLI version by running:
expo --version
If you’re not running the latest version, update Expo CLI using:
npm install -g expo-cli
Step 3: Delete `node_modules` and `package-lock.json`
A classic troubleshooting technique is to remove the `node_modules` directory and `package-lock.json` file. This will force npm to reinstall dependencies from scratch. Run the following commands:
rm -rf node_modules rm package-lock.json
Step 4: Run `npm install` with Flags
Now, let’s try reinstalling dependencies using npm with some additional flags to help diagnose the issue:
npm install --legacy-peer-deps --force --verbose
The `–legacy-peer-deps` flag tells npm to ignore peer dependency conflicts, while `–force` forces the installation of dependencies. The `–verbose` flag provides more detailed output to help us identify the issue.
Step 5: Check for Permission Issues
If you’re still encountering issues, it’s possible that permission problems are at play. Try running the following command to change the ownership of the `node_modules` directory:
sudo chown -R $USER:staff node_modules
Replace `$USER` with your actual username.
Step 6: Disable Apple M1 Chipset Optimization
Newer MacOs M1 chipsets can sometimes cause issues with npm. Let’s try disabling the optimization by setting an environment variable:
export Rosetta_SIMD_OPTIONS=1
Then, retry running `npm install`:
npm install
Step 7: Try a Clean npm Cache
Sometimes, a corrupted npm cache can cause issues. Try clearing the cache using:
npm cache clean --force
Followed by:
npm install
Step 8: Reinstall Expo and React Native
If all else fails, let’s try reinstalling Expo and React Native:
npm uninstall -g expo-cli npm uninstall react-native
Then, reinstall Expo and React Native:
npm install -g expo-cli npm install react-native
Troubleshooting Common Errors
While following the steps above, you might encounter some common errors. Here are some solutions to help you overcome them:
Error | Solution |
---|---|
Error: EACCES: permission denied | Run `npm install` with sudo: `sudo npm install` |
Error: npm ERR! code ELIFECYCLE | Delete `node_modules` and `package-lock.json`, then run `npm install` |
Error: npm ERR! code ENOENT | Verify Node.js and npm versions, then try reinstalling Expo and React Native |
Conclusion
By following these steps, you should be able to resolve the “npm install failed” error in your Expo React Native project on MacOs M1. Remember to be patient and methodical in your troubleshooting approach, as each step builds upon the previous one.
If you’re still encountering issues, don’t hesitate to reach out to the Expo community or seek help from a fellow developer. Happy coding, and may the npm be with you!
Bonus Tip: Optimizing Your System for npm and Expo
To avoid future npm install failures, consider optimizing your system by:
- Updating your Node.js and npm versions regularly
- Using a package manager like nvm to manage multiple Node.js versions
- Configuring your system to use a faster npm registry like Verdaccio
- Regularly cleaning your npm cache
By taking these proactive measures, you’ll be well-equipped to tackle any npm install issues that come your way!

Frequently Asked Questions
Stuck with an npm install failure in your Expo React Native project on MacOs M1? Don’t worry, we’ve got you covered! Check out these frequently asked questions to troubleshoot and get back to building your app.
Why does npm install fail with an error message about a missing Xcode installation?
This issue often occurs because Expo requires Xcode to build iOS projects, and your MacOs M1 might not have it installed. Simply download and install Xcode from the App Store, then try running `npm install` again.
How do I fix the error “node-gyp rebuild failed” during npm install?
This error usually stems from compatibility issues with Node.js and Python. Try reinstalling Node.js using Homebrew by running `brew uninstall node` and then `brew install node`. Afterward, run `npm install –build-from-source` to rebuild the dependencies.
Why do I get a “ENOENT: no such file or directory” error during npm install?
This error typically occurs due to a missing directory or file in your project. Ensure that your project directory is correct and has the necessary files. You can also try deleting the `node_modules` directory and running `npm install` again to reinstall the dependencies.
How do I resolve the error “npm ERR! code EGPUUnsupported” during npm install?
This error is specific to Expo and MacOs M1. Try setting the `ENABLE_EXPERIMENTAL_GL_RENDERER` environment variable to `false` by running `export ENABLE_EXPERIMENTAL_GL_RENDERER=false` before running `npm install`. This should resolve the issue.
What if I’ve tried all the above solutions and npm install still fails?
If none of the above solutions work, try resetting your npm cache by running `npm cache clean –force`, then delete the `node_modules` directory and run `npm install` again. You can also try updating your Expo CLI to the latest version using `npx expo-cli@latest`.
If the issue persists, you may want to seek help from the Expo community or create a new issue on GitHub with detailed error logs for further assistance.
