0.102.4 is outdated and old version. Actual version is 0.103.5 or newer.

Here is some reasons why you can't update ClamAV:

1. Amazon remote repository is outdated and not maintained anymore (you should to update your Linux OS to be able migrate to new repository). This case is most possible if you using current EC2 instance couple of years without updates
2. Local repository info is outdated. Try to run sudo yum update before ClamAV installation to update local info

If sudo yum update won't help try to Download newest clamav-0.104.2.linux.x86_64.rpm and install it manually (don't forget to delete old versions first).

I figured out that I was using the react-navigation-tabs package in my application.Go to node_modules > react-navigation-tabs > node_modules > react-navigation-tab-view > src > TabBar.js.

In this TabBar.js file, you will find ref={el => (this._scrollView = el && el.getNode())} on line 412.

If you check this._scrollView is assigned to _scrollView: ?ScrollView; on line 147 which is imported from ScrollView of react-native.

Since ScrollView does not contain any el or el.getNode() method,the bundler throws the error showing el.getNode() is undefined.

To fix this follow these steps:

• Use Import {Animated} from react-native;
• On line 147, change fault code to _scrollView: Animated.ScrollView;
• On line 412, change faulty code to (this.scrollView = el && (el.getNode ? el.getNode() : el))
• Clean and rebuild your project,it should work fine now.

I was able to resolve this error by following this link

Follow the instructions from the upgrade helper. Your Podfile will likely be very minimal once you're done).

Podfile.lock and the Pods directory can be safely deleted (and probably should for something like this, since it's a big change) -- they'll be regenerated on pod install.

After upgrading to react-native 0.63.3 took the same error.

The root cause of this was my project only had objective-C files.

The solution is just to add an empty swift file under your project in xcode and all of your linking errors will be solved.

I fixed the problem by updating dependencies and devDependencies to the latest versions. I guess the better solution would be to find out what exactly one needed to be update. But the main thing for now is that app finally runs :)

To install PHP 7.4 along with all related packages (extensions) you can use Remi's repository, it even has a setup wizard that will walk you through the process here https://rpms.remirepo.net/wizard/

But you'll have to uninstall your current php version, what I do in these situations is just run php -m, save all the modules I have and know my web app will use and then do a yum remove php* to remove all traces but review carefully all the removed packages before accepting as it may remove other packages because of dependencies.

Can you try to remove all the linked React Native library in Xcode ?

1. Open Project.xcworkspace file in Xcode
2. Go to project navigator tab
3. Go to Build Phases tab
4. Then under Link Binary With Libraries section: Remove all binaries -libRCT*

With RN 60+ there are now included in the Pods project.

The most likely reason for the issue is the use of Amazon Linux 1 (amzn1). Amazon Linux 1 uses sysvinit, instead of systemd.

The recommended solution is to use Amazon Linux 2 which does support systemd

There might be a better way, but this worked:
