Cocos2dx - error using sdkbox to import plugins

Question

I’m using the sdkbox (v0.5.6.7) in a project Cocos2dx (v3.7.1) but every time I run sdkbox gives the following error:

$> sdkbox import facebook
 _______ ______  _     _ ______   _____  _     _
 |______ |     \ |____/  |_____] |     |  \___/

That same mistake happened while testing the sdkbox with the version 3.6 of cocos2dx, then updated because I thought it was an error in the installation sdkbox (because before 3.7 it was not bundled with the framework) or something with version 3.6. After I updated the error persists. I already asked uncle google and nothing.

I didn’t touch anything; what I did was install version 3.7.1 through setup.py, then created a project from scratch, then copied my source files that were from the other project, and tried to import the plugin, but gives this error. The project is beautiful, builds the executables quiet, but I can not use the sdkbox. Someone knows what’s wrong?
