Hi, I am trying to install rdflib through pip to integrate with the dynamo platform. But, I am getting an error message,

"Warning: AttributeError : ‘NoneType’ object has no attribute ‘isatty’ [’ File “”, line 4, in \n’, ’ File “----------------\rdflib\init.py”, line 99, in \n and sys.stderr.isatty()\n’]".

The "init.py" is one of the default files existing within the rdflib folder.

Could anyone help me to resolve this issue?
Thanks
