Error with pycocotools

[EngrStudent]

Please briefly describe your problem and what output you expect. I got the following error when trying to install the fastai package using r.

I think it wants to convince me to purchase Microsoft Visual C++ 14.0, but that is not in my budget. I'm still paying off my student loans. (@Michael Nikkhoo)

My command was: fastai::install_fastai(gpu = FALSE, cuda_version = '10.1', overwrite = FALSE)

There was a ton of text and then this error in the middle:

copying pycocotools\cocoeval.py -> build\lib.win-amd64-3.6\pycocotools
    copying pycocotools\mask.py -> build\lib.win-amd64-3.6\pycocotools
    copying pycocotools\__init__.py -> build\lib.win-amd64-3.6\pycocotools
    running build_ext
    skipping 'pycocotools\_mask.c' Cython extension (up-to-date)
    building 'pycocotools._mask' extension
    error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/
    ----------------------------------------

Then it gave me this as the final result:
