Cannot initialize a parameter of type ‘NSArray<id<RCTBridgeModule>>
今天发现,XCode12.5上,打开RN某工程,环境报错,有两个方法,第一个方法在podfile文件里替换:
post_install do |installer|
## Fix for XCode 12.5
find_and_replace(
"../node_modules/react-native/React/CxxBridge/RCTCxxBridge.mm",
"_initializeModules:(NSArray<id<RCTBridgeModule>> *)modules",
"_initializeModules:(NSArray<Class> *)modules")
find_and_replace(
"../node_modules/react-native/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm",
"RCTBridgeModuleNameForClass(module))",
"RCTBridgeModuleNameForClass(Class(module)))"
)
end
def find_and_replace(dir, findstr, replacestr)
Dir[dir].each do |name|
text = File.read(name)
replace = text.gsub(findstr,replacestr)
if text != replace
puts "Fix: " + name
File.open(name, "w") { |file| file.puts replace }
STDOUT.flush
end
end
Dir[dir + '*/'].each(&method(:find_and_replace))
end
然后pod install即可。
第二个方法:如果没有podfile文件,可以直接替换RCTCxxBridge.mm里的- (void)registerAdditionalModuleClasses方法替换成:

RCTTurboModuleManager.mm文件里- (id<RCTTurboModule>)provideRCTTurboModule里出错的地方替换成:

保存,重新编译即可。
2021.9.29 贴出源码:
1.修改registerAdditionalModuleClasses的传入参数:
- (void)registerAdditionalModuleClasses:(NSArray<Class> *)modules
{
std::lock_guard<std::mutex> guard(_moduleRegistryLock);
if (_moduleRegistryCreated) {
NSArray<RCTModuleData *> *newModules = [self _initializeModules:modules withDispatchGroup:NULL lazilyDiscovered:YES];
assert(_reactInstance); // at this point you must have reactInstance as you already called reactInstance->initialzeBridge
_reactInstance->getModuleRegistry().registerModules(createNativeModules(newModules, self, _reactInstance));
} else {
[self registerModulesForClasses:modules];
}
}
RCTTurboModuleManager.mm文件文件里provideRCTTurboModule函数:
- (id<RCTTurboModule>)provideRCTTurboModule:(const char *)moduleName
{
Class moduleClass;
id<RCTTurboModule> module = nil;
{
std::unique_lock<std::mutex> lock(_rctTurboModuleCacheLock);
auto rctTurboModuleCacheLookup = _rctTurboModuleCache.find(moduleName);
if (rctTurboModuleCacheLookup != _rctTurboModuleCache.end()) {
return rctTurboModuleCacheLookup->second;
}
if (_invalidating) {
// Don't allow creating new instances while invalidating.
return nil;
}

}
if ([module respondsToSelector:@selector(setTurboModuleLookupDelegate:)]) {
[module setTurboModuleLookupDelegate:self];
}
_rctTurboModuleCache.insert({moduleName, module});
}
