I think it's called FrameProcessorPlugin now, no?

react-native-vision-camera/package/ios/Frame Processor/FrameProcessorPlugin.h

Lines 14 to 28 in 5487102

	/// The base class for a Frame Processor Plugin which can be called synchronously from a JS Frame
	/// Processor.
	///
	/// Subclass this class in a Swift or Objective-C class and override the `callback:withArguments:`
	/// method, and implement your Frame Processing there.
	///
	/// Use `[FrameProcessorPluginRegistry addFrameProcessorPlugin:]` to register the Plugin to the
	/// VisionCamera Runtime.
	@interface FrameProcessorPlugin : NSObject
	/// The actual callback when calling this plugin. Any Frame Processing should be handled there.
	/// Make sure your code is optimized, as this is a hot path.
	- (id _Nullable)callback:(Frame* _Nonnull)frame withArguments:(NSDictionary* _Nullable)arguments;
	@end

Where did you even get the name FrameProcessorPluginBase from? It's not in the docs either, maybe this is a left-over artefact of a V2 implementation. In V3 it's just called FrameProcessorPlugin

@mrousavy Thank you for your reply. I followed the following steps to proceed。

I integrated it here according to the document https://react-native-vision-camera.com/docs/guides/frame-processor-plugin-list The document integrates plugins, it seems that the plugins here are not compatible with the v3 version anymore

Same here for me. All I did is to follow the manual process from npx vision-camera-plugin-builder ios. After registering the global plugin name and setting up the babel.config.js, I stumbled upon the issue mentioned above

[NoahSimajji]

Guys? i encounter this issue too. Any solution?

[Rakedd]

Ok guys here's the deal, the error come from the plugin vision-camera-ocr, not this repo. Related here, and there's a ongoing PR here, so i retract my comment @mrousavy, it's indeed closed and not relevant here
And thank you for your work 🫡.
