Unable to load the library ‘netty_transport_native_kqueue_x86_64‘

出现该错误：Unable to load the library 'netty_transport_native_kqueue_x86_64', trying other loading mechanism.

其实不是错误，而是：

Those are DEBUG logs, not errors. Just ignore them (you're not even supposed to have DEBUG enabled on Netty in production).

FYI, Netty has a fallback mechanism. A few lined below this stacktrace, you should see something like i.n.u.i.NativeLibraryLoader - Successfully loaded the library /var/folders/3m/b2yp9rr56s30thdsxrq7hy200000gn/T/libnetty_tcnative_osx_x86_644093229984461983342.dylib.
