  Package cairo was not found in the pkg-config search path.
  Perhaps you should add the directory containing `cairo.pc'
  to the PKG_CONFIG_PATH environment variable
  No package 'cairo' found
  Command '['pkg-config', '--print-errors', '--exists', 'cairo >= 1.15.10']' returned non-zero exit status 1.

解决方法：

apt-get install libcairo2-dev

pip install pycairo -U

安装完后，在执行：

pip install pyds-1.1.1-py3-none-linux_aarch64.whl
