Answer 1

I've tried every thing, at last I reinstated windows and it solved.

Answer 2

pip install wheel

I had a same problem. Based on your file named forex.py , I assume you are trying to follow these tutorials from:

• Part Time Larry
• Daniel Rodriguez

In my case, I solved with pip install wheel in pipenv virtual environment.

Explanation:

• What is the error: Because the IbPy2 is written in Python2 and it's not running on proper Python version. Please read this answer for detail. Python 2 and Python 3.

• Why does it occur: When you create a virtual environment with pipenv , there is no wheel installed. Pipenv installs without wheel and the message is like this: Using legacy 'setup.py install' for IbPy2, since package 'wheel' is not installed. And then it was recognized as the code written in Python2.

• How to solve: Install wheel first with pip install wheel . And then install IbPy2 with pip install IbPy2 , then it will be properly installed and recognized as Python3 code. So you will not see the Python2 syntax error anymore.
