Error operation.rb

Please,

Has anyone seen this error?

RuntimeError: Could not execute command to start test server
from C:/Ruby23/lib/ruby/gems/2.3.0/gems/calabash-android-0.9.0/lib/calabash-android/operations.rb:734:in start_test_server_in_background' from C:/Ruby23/lib/ruby/gems/2.3.0/gems/calabash-android-0.9.0/lib/calabash-android/operations.rb:152:in start_test_server_in_background'

The error occurs while executing the command "start_test_server_in_background", does not open the application. The lines that have errors are in operation.rb that call the command I execute.

I'm working with ruby23, windows10
