fasttext building error as Python module in Docker container

I have been trying to install fasttext in a docker container. I am getting the same error after trying many pre-installations.

Essentially, I have the same code in windows and I installed via pip in PyCharm. It works without any problem. I thought in Linux based systems, it would be easier. However, I could not get rid of the installation problem.

Here is the error snippet:

Am I missing something? The pre-requirements are specified as:

 fastText builds on modern Mac OS and Linux distributions. Since it uses C++11 features, it requires a  compiler with good C++11 support. You will need Python (version 2.7 or ≥ 3.4), NumPy & SciPy and  pybind11.

I have tried installing Numpy and sCipy via pip3, various gcc versions, install fasttext via only pip install fasttext etc. Nothing worked so far.

Can someone help with this error, please?
