GCC + Python + Pip install errors got me like, "i can't even"

In my free time, I have been trying to pick up working on my side project, techconferenc.es again. However, I couldn’t even seem to simply pip install -r requirements.txt without getting errors.

error: command 'gcc-4.9' failed with exit status 1

This error has been tripping me up for so long! Googling for hours on the weekend, racking my head about what could possibly fix this, and trying every solution I found. Nothing.

Until, I found this blog post after the 321934th Google search pertaining to this issue. Apparently it’s a temporary fix, but OMG IT WORKED.
