Cannot use Env::SetInstanceData

[kaysonwu]

napi_set_instance_data Added in: v12.8.0, v10.20.0 N-API version: 6.

The following is my version information：

nodejs: 12.14.1
NAPI_VERSION: 5

Currently using NAPI_VERSION judgment, so I cannot use Env::SetInstanceData.

Hi @kaysonwu,
the function napi_set_instance_data was added for the first time in Node.js version v12.8.0 and v10.20.0. At that time the function was considered like experimental and then it has been promoted like stable api with N-API version 6.
You should always refer to NAPI_VERSION to identify what function is available.
In you specific case the function was available, but experimental so you can try to set NAPI_VERSION to 6 and define the NAPI_EXPERIMENTAL.
In your binding.gyp file:

{
   "targets": [
        {
            "defines": [ "NAPI_EXPERIMENTAL", "NAPI_VERSION=6" ],
        }
   ]
}

I hope that this help you.
