ImportError: Library "fontconfig" not found #88

Closed AuthenticEshkinKot closed 5 years ago

AuthenticEshkinKot commented 5 years ago

I installed Docker image "gym-duckietown" on two separate PC, with Gentoo and with Ubuntu 16.04 in VirtualBox. Installation steps:

  1. Install Docker
  2. docker pull duckietown/gym-duckietown
  3. docker run -it duckietown/gym-duckietown bash

In image's bash I executed next commands:

  1. Xvfb :0 -screen 0 1024x768x24 -ac +extension GLX +render -noreset &> xvfb.log &
  2. export DISPLAY=:0
  3. ./manual_control.py --env-name Duckietown-udem1-v0

The last command failed with message "ImportError: Library "fontconfig" not found." Full log - https://pastebin.com/5S9V7QNF

It seems that this might be the issue here?

Have you made sure that you can find fontconfig.pc?

Please comment again if you seem to still have this issue, but I'll close it for now since it seems like it might be a unique system thing.

I've tried the suggested approach and still cannot get it to work. The stack trace is similar stemming from pyglet. I looked up the libfontconfig1-dev path and indeed there is no fontconfig.pc file and unfortunately my docker shell doesn't find any packages when i try to install fontconfig or libfontconfig1-dev

Same here as @BryannX mentioned. I tried to install the package with apt install libfontconfig1-dev command but the package could not be found:
