SDL2 Error when using pixels.drawText()

[JinnRoad]

Warning: For others who find this, the solution below mysteriously stopped working. My solution at this link works (for now):
Araq/pixels#2 (comment)

# From book: "Mastering Nim, 2nd Edition" Chapter 3

import pixels

drawText 50, 50, "hello world!", 30, Red

Error

/home/user/.nimble/pkgs2/pixels-0.1.0-d6b41f4a271e9eedfe1e6e8c13d7fb6f010b6c23/pixels.nim(12) drawText
Error: unhandled exception: font could not be created, SDL error Couldn't open /usr/share/fonts/TTF/FiraSans-Regular.ttf [SDLException]
Error: execution of an external program failed: '/home/user/.cache/nim/ch03_text_d/ch03_text_4D8F0A24490781C34D568D66A34AA20B6C408DD8'

Fix

# Ch3 requires a text font.
# Navigate to the directory where you're running your nim code. The below
# command downloads to the current directory a font from nim's SDL2 library,
# renames it to FiraSans-Regular, which is the font SDL2 is looking for.
wget https://github.com/nim-lang/sdl2/blob/master/examples/liberation-sans.ttf -O FiraSans-Regular.ttf

# The font is expected to be in /usr/shared/fonts/TTF, and you can put the font
# there instead, which requires the use of sudo.

That's a "pixels" library problem, not an SDL problem. Also, it might just be an installation problem.
