[Test Error]no egl devices found Aborted (core dumped)

[studycat520]

Thanks for your great work!I got an error when running

python tests/square_test.py

The output is "no egl devices found Aborted (core dumped)".I have tried many solutions about all the same issues but they didn't work. Some tests were: 1、The output of subprocess

import dirt.rasterise_ops
import subprocess
subprocess.call(['ldd', dirt.rasterise_ops._lib_path + '/librasterise.so'])

2、The output of ldd dirt/librasterise.so

3、The output of ls -l /usr/lib*/*/GL So what's the problem? What can I do to solve this error of square_test? Thank you very much for helping me
