Fixing “Please update Expo Go” error (even when it’s already updated)

Hala — Tue, 02 Jun 2026 01:49:46 +0000

While developing a React Native app using Expo, I ran into a really confusing issue.

Every time I tried to run my project, the app would open normally but immediately show this message inside the app:

“Please update Expo Go to the latest version from Google Play Store”

The strange part?
My Expo Go was already updated to the latest version from the Google Play Store.

I double-checked multiple times, uninstalled and reinstalled it, but the error still kept showing.

Environment
React Native (Expo)

Expo SDK (latest at the time of writing)

Android (Google Play Store version of Expo Go)

No errors in terminal

What I tried

Before finding the actual fix, I tried the usual debugging steps:

Reinstalling Expo Go from Google Play Store

Logging out and logging back into Expo

Reconnecting the project

Restarting Metro bundler

Clearing cache and node modules

Rebuilding the project

Nothing worked ❌

Everything looked fine… except the error inside the app.

The real issue

The problem wasn’t in my code or Expo setup.

It was a version mismatch between the Play Store Expo Go build and the required SDK version of my project.

Even though the app showed as “updated”, it was still not compatible with my project’s Expo SDK version.

The solution

Instead of relying on the Play Store version, I installed the latest Expo Go build manually from the official source.

After installing it manually:

The app launched successfully

The error disappeared immediately

Everything worked as expected

Key takeaway

If you ever see this message:

“Please update Expo Go…”

even when your app is already updated from the Play Store:

👉 Don’t assume it’s actually up to date
👉 Try installing the latest version manually from the official Expo releases instead

It saved me hours of confusion and debugging.

Final thoughts

This was one of those annoying issues where everything looks correct, but the problem is actually in version alignment between tools rather than your code.

Hopefully this helps someone avoid the same headache 🙂

How Windows Caused a Fatal “typeof” Error in Expo EAS Build — And Why Linux Solved It

Introduction

I recently faced one of the strangest and most frustrating technical issues in my development journey. My mobile application was working perfectly during development, but everything broke when I tried to build the production Android version.

What made the situation worse was that the error appeared to be unrelated to my code. After several days of troubleshooting, the solution turned out to be something I never expected: the operating system itself.

This article documents the full technical journey in hopes that it helps any developer facing a similar issue.

The Fatal Error

The project ran normally in development mode using Expo. However, when attempting to build the Android production version using EAS Build:

eas build --platform android --profile production

The process suddenly stopped and repeatedly produced the following error:

SyntaxError: Unexpected token 'typeof'
at Object.compileFunction (node:vm:360:18)
at wrapSafe (node:internal/modules/cjs/loader:1055:15)

The error appeared dozens of times and prevented the build from completing.

Engineering Analysis

This was not a logic error in the application code.

Instead, it was an Interpreter Compatibility Conflict between the Node.js engine and the Windows environment.

What was happening internally?

• EAS Build calls internal Expo dependencies such as Metro configuration packages.
• These packages rely on modern JavaScript syntax.
• On Windows, Node.js failed to parse the "typeof" keyword inside the dependency source code.
• Node interpreted it as an unexpected token, even though the syntax was valid.

In short:

«The build system failed before even reaching my application code.»

Failed Troubleshooting Attempts

I exhausted nearly every common solution used by developers on Windows environments:

1️⃣ Removing Dependencies

• Deleted "node_modules"
• Deleted "package-lock.json"
❌ Result: Failed
Reason: The issue was not corrupted packages, but how the OS interpreted them.

2️⃣ Changing Node.js Versions

• Installed multiple LTS versions
❌ Result: Failed
Reason: The conflict originated from Windows shell environment variables and system-level parsing behavior.

3️⃣ Clearing npm Cache

npm cache clean --force

❌ Result: Failed
Reason: Temporary files were not responsible.

4️⃣ Updating Build Tools

• Updated EAS CLI
• Updated Expo CLI
❌ Result: Failed
Reason: Tooling was healthy — the OS environment was not.

5️⃣ Modifying Babel & App Configurations

• Edited "babel.config.js"
• Edited "app.json"
❌ Result: Failed
Reason: The error occurred before Babel was even invoked.

The Turning Point — Migrating to Linux

At this stage, Windows became a complete roadblock.

Instead of wasting more time, I made a strategic engineering decision:

«Move the entire development environment to a Unix-based system.»

Steps Taken:

✅ Installed VirtualBox
✅ Created a virtual machine running Ubuntu Linux
✅ Installed a fresh Node.js environment
✅ Reinstalled Expo and EAS CLI
✅ Cloned the same project files without modification

The Critical Test

Inside Linux, I ran the exact same command:

eas build --platform android --profile production

Result:

✅ The error disappeared immediately
✅ The build process started successfully
✅ No code changes were required
✅ No dependency changes were required

The exact same project that failed on Windows worked flawlessly on Linux.

Technical Explanation

Linux systems are Unix-based, which aligns with the native environment used to design Node.js and Expo tooling.

This provides:

• Consistent file path handling
• Stable environment variable management
• Reliable JavaScript engine behavior
• Better compatibility with modern build systems

Meanwhile, Windows introduced hidden interpreter conflicts that disrupted dependency parsing.

Key Lesson

Sometimes the problem is not in:

❌ Your code
❌ Your libraries
❌ Your build tools

But in the execution environment itself.

When facing persistent, unexplainable build errors:

«Changing the operating system may be the most efficient solution.»

الملخص

واجهت خطأ غريب أثناء بناء نسخة الإنتاج لتطبيقي باستخدام Expo.
التطبيق كان يعمل بشكل طبيعي في التطوير، لكن أثناء تنفيذ أمر بناء الأندرويد ظهر خطأ:

SyntaxError: Unexpected token 'typeof'

بعد تجربة جميع الحلول التقليدية على نظام Windows مثل حذف المكتبات وتحديث Node وتنظيف الكاش — استمرت المشكلة.

اتضح أن السبب لم يكن في الكود، بل في تعارض بيئة Windows مع طريقة تفسير Node.js للمكتبات الحديثة.

الحل كان بالانتقال إلى نظام Linux عبر جهاز وهمي Ubuntu.

بمجرد تشغيل نفس المشروع ونفس أمر البناء على Linux:
اختفى الخطأ فوراً ونجح البناء بدون أي تعديل.

الدرس المهم:

أحياناً بيئة التشغيل نفسها هي سبب المشكلة، وتغيير النظام قد يكون الحل الجذري.
