Are you tired of encountering the dreaded “Ngrok error installing @react-navigation/native” issue while trying to set up your React Native project? You’re not alone! This error can be frustrating, especially when you’re excited to start building your app. But fear not, dear developer, for we’ve got you covered. In this article, we’ll take you by the hand and walk you through the step-by-step process of resolving this pesky error.
What is Ngrok and Why Do We Need It?
Before we dive into the solution, let’s take a quick detour to understand what Ngrok is and why it’s essential for our React Native project.
Ngrok is a reverse proxy that creates a secure tunnel from a public endpoint to a locally running development web service. In simpler terms, it allows you to expose your local development server to the outside world, making it accessible over the internet. This is particularly useful when you need to test your app on a physical device or share it with others for feedback.
Why Do We Need Ngrok for @react-navigation/native?
@react-navigation/native is a popular library for React Native that provides an easy-to-use navigation system for your app. However, during the installation process, Ngrok is required to create a secure tunnel to your local development server. This enables the library to work seamlessly with your app, allowing you to navigate between screens and test your app on a physical device.
The Error: Ngrok Error Installing @react-navigation/native
So, what happens when you encounter the “Ngrok error installing @react-navigation/native” issue? You might see an error message similar to this:
npm ERR! code E404
npm ERR! 404 Not Found: @react-navigation/native@~5.7.0
npm ERR! A complete log of this run can be found in:
npm ERR! /Users/your-username/.npm/_logs/2022-02-20T14_30_30_755Z-debug.log
This error occurs when Ngrok fails to install or configure correctly, preventing the @react-navigation/native library from installing successfully.
Step-by-Step Solution to Fix the Ngrok Error
Don’t worry, we’ve got a comprehensive solution to fix this issue. Follow these steps, and you’ll be back to building your app in no time!
Step 1: Check Your Internet Connection
Ensure you have a stable internet connection. This might seem obvious, but a weak or intermittent connection can cause the installation process to fail.
Step 2: Verify Ngrok Installation
Let’s check if Ngrok is installed correctly on your system:
npm install ngrok -g
This command will install Ngrok globally on your system. If you’ve already installed Ngrok, you can skip this step.
Step 3: Configure Ngrok
Next, let’s configure Ngrok to create a secure tunnel to your local development server:
ngrok http 8081
This command will create a secure tunnel to your local development server on port 8081. You can choose a different port if needed.
Step 4: Set the NGROK_URL Environment Variable
Now, let’s set the NGROK_URL environment variable to point to your Ngrok tunnel:
export NGROK_URL=https://your-ngrok-url.ngrok.io
Replace “your-ngrok-url” with the actual URL provided by Ngrok. You can find this URL in the Ngrok terminal output.
Step 5: Install @react-navigation/native
With Ngrok configured and the environment variable set, you’re ready to install @react-navigation/native:
npm install @react-navigation/native
This should install the library successfully. If you still encounter issues, try reinstalling the library or checking the installation logs for errors.
Troubleshooting Common Issues
Encountered an issue during the installation process? Don’t worry, we’ve got you covered! Here are some common issues and their solutions:
| Error Message | Solution |
|---|---|
| npm ERR! code E404 | Check your internet connection and try reinstalling the library. |
| Ngrok tunnel not found | Ensure Ngrok is installed and configured correctly. Restart the Ngrok tunnel and set the NGROK_URL environment variable again. |
| Permission denied error | Run the installation command with administrator privileges or try reinstalling the library using a package manager like Yarn. |
Conclusion
And that’s it! By following these steps, you should be able to resolve the “Ngrok error installing @react-navigation/native” issue and get back to building your React Native app. Remember to check your internet connection, verify Ngrok installation and configuration, set the NGROK_URL environment variable, and install @react-navigation/native.

Frequently Asked Question
Ngrok error installing @react-navigation/native? Don’t worry, we’ve got you covered!
What is the Ngrok error, and why does it occur while installing @react-navigation/native?
The Ngrok error typically occurs when there’s an issue with the Ngrok tunneling service, which is used by React Native to simulate a web server on your local machine. This error can happen due to various reasons, including conflicts with existing Ngrok instances, incorrect configurations, or even network connectivity issues.
How can I resolve the Ngrok error by stopping the existing Ngrok process?
To stop the existing Ngrok process, you can use the command `lsof -i :4040` (on macOS/Linux) or `netstat -tlnp | findstr 4040` (on Windows) to identify the Ngrok process ID. Then, use the command `kill
What if I’ve tried stopping the Ngrok process, but the error still persists?
If stopping the Ngrok process doesn’t work, try deleting the Ngrok binary file located at `~/.ngrok2/ngrok`. Then, reinstall Ngrok using `npm install ngrok` or `yarn add ngrok`. After reinstalling Ngrok, try installing @react-navigation/native again to see if the error resolves.
Is there a way to completely disable Ngrok during the installation of @react-navigation/native?
Yes, you can disable Ngrok by setting the `RNC_TUNNEL_ENABLED` environment variable to `false`. On macOS/Linux, use the command `RNC_TUNNEL_ENABLED=false npm install @react-navigation/native`, and on Windows, use the command `set RNC_TUNNEL_ENABLED=false && npm install @react-navigation/native`. This will bypass Ngrok during the installation process.
What if none of the above solutions work, and I’m still stuck with the Ngrok error?
If none of the above solutions work, it’s possible that there’s an issue with your system configuration or network setup. Try reinstalling Node.js, npm, or yarn, and then reinstall @react-navigation/native. If the issue still persists, consider seeking help from the React Native community or a development expert for further assistance.
