modify Cocos2d-x root/external/config.json to update the dependency version. For v3.x the dependency version is v3-deps-92, and for v2.x it is v2-deps-5
execute the download-deps.py script in your Cocos2d-x root.
if i do like what you said, everything will be ok ?
Yes, that is the way I understand it too and I wrote those instructions with one of our engineers assisting.
Thank you ，and i have tryied like that, and it worked.

You just need to update your libcurl,follows the answer of below link:-
Deploying this version is not a good idea by any means. Please don’t deploy this version.
Actually the project is pre-developed in this version and its in closure stage and it will take a lot of changes for upgrading to above versions,therefore for this project only,i have to stick to this version only.
Thanks for your suggestion.I will develop further games with above versions.
I would strongly consider trying to upgrade. Your version is not a production build.
Thanks slackmoehrle!
For the time being,i have uploaded the project with this version but surely develop next project with upper version of Cocos2dx.
After changing the dependency version to v3-deps-92 and executing download-deps.py everything ran ok. But then when I try to build my project I’m now getting the following error:
error: no matching function for call to 'rapidjson::GenericValue<rapidjson::UTF8<> >::AddMember(const char [10], const char*&, rapidjson::GenericDocument<rapidjson::UTF8<> >::AllocatorType&)'action.AddMember("classname", str2, allocator);
Any help would be greatly appreciated!
EDIT: I also get the following error:
json/document.h:1107:5: error: no type named 'Type' in 'struct rapidjson::internal::DisableIf<rapidjson::internal::OrExpr<rapidjson::internal::IsPointer<const char*>, rapidjson::internal::IsGenericValue<const char*> >, rapidjson::GenericValue<rapidjson::UTF8<> >&>'
