The FullLoaderclass is only available in PyYAML 5.1 and later. Version 5.1 was released on March 13, 2019and has probably not filtered down to many distributions yet.
该FullLoader班仅在PyYAML 5.1及更高版本。5.1 版于2019 年 3 月 13 日发布，可能尚未筛选到许多发行版。
You can check the version of PyYAML by inspecting yaml.__version__:
您可以通过检查来检查 PyYAML 的版本yaml.__version__：
Python 2.7.15 (default, Oct 15 2018, 15:24:06)
[GCC 8.1.1 20180712 (Red Hat 8.1.1-5)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

>>> yaml.__version__
'3.13'
