Answer 1

问题出在Python的错误版本中：

https://pypi.org/project/fonttools/

FontTools 4.x requires Python 3.6 or later. FontTools 3.x requires Python 2.7 or later.

我尝试在python2中使用最新的fontcools。安装Python工具的问题已解决：

apt-get update
apt-get install -y python3 python-pip
pip install  upgrade pip
hash -r
pip install fonttools

您需要卸载fontTools，然后安装它的py27分支。您使用的版本与Python2.7不向后兼容
