[AxelTdev]

Hi, When i try to install python packages with: sudo pip install oandapy

There is this error : Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-xmyyfrsm/pysimplemodel/ My Python version is 2.7.13. This is the complete output: ` Complete output from command python setup.py egg_info: Traceback (most recent call last): File "", line 1, in File "/tmp/pip-install-xmyyfrsm/pysimplemodel/setup.py", line 6, in from simple_model.version import version File "/tmp/pip-install-xmyyfrsm/pysimplemodel/simple_model/init.py", line 2, in from .builder import model_builder, model_many_builder File "/tmp/pip-install-xmyyfrsm/pysimplemodel/simple_model/builder.py", line 3, in from .models import Model File "/tmp/pip-install-xmyyfrsm/pysimplemodel/simple_model/models.py", line 5, in from .fields import ModelField, Unset File "/tmp/pip-install-xmyyfrsm/pysimplemodel/simple_model/fields.py", line 24 return (f'ModelField(model_class={self.model_class!r}, name={self.name!r}, ' ^ SyntaxError: invalid syntax
