Having trouble building the React Native app after adding react-native-vector icons?

A recent project I've been working on involved adding react-native-vector-icons using react-native 0.63.4. However, during the build process, I encountered an error when running the command npx react-native run-ios in the terminal. The warnings/errors displayed were as follows:

In file included from /Users/newuser/workspace/programming/mobile/numbers/ios/Pods/Headers/Public/Flipper-Folly/folly/json.h:48:
In file included from /Users/newuser/workspace/programming/mobile/numbers/ios/Pods/Headers/Public/Flipper-Folly/folly/dynamic.h:796:
...
(1 failure)

Attempting to build the project with Xcode also resulted in the following error:

/Users/newuser/workspace/libevent/event.h:44:10: 'event2/event-config.h' file not found

Even after trying commands like pod install and pod update, the app still refuses to build.

Answer №1

Encountered an issue here, make sure to troubleshoot your installation as a common problem could be missing fonts in infoplist. Check your infoplist file and ensure it includes the following:

<key>UIAppFonts</key>
<array>
    <string>AntDesign.ttf</string>
    <string>Entypo.ttf</string>
    <string>EvilIcons.ttf</string>
    <string>Feather.ttf</string>
    <string>FontAwesome.ttf</string>
    <string>FontAwesome5_Brands.ttf</string>
    <string>FontAwesome5_Regular.ttf</string>
    <string>FontAwesome5_Solid.ttf</string>
    <string>Fontisto.ttf</string>
    <string>Foundation.ttf</string>
    <string>Ionicons.ttf</string>
    <string>MaterialCommunityIcons.ttf</string>
    <string>MaterialIcons.ttf</string>
    <string>Octicons.ttf</string>
    <string>SimpleLineIcons.ttf</string>
    <string>Zocial.ttf</string>
    <string>icomoon.ttf</string>
</array>

If not resolved, try running

react-native link react-native-vector-icons

Alternatively, consider using the legacy build system by navigating to

workspace settings -> build system -> legacy build system

Another factor to consider is

If you are using use_frameworks! in your Podfile, remember that you need to dynamically load the icon font by executing Icon.loadFont() during application bootstrapping.
