ModuleNotFoundError: No module named '_lzma'

修复方法一：backports

• 安装 backports.lzma

yum install xz-devel -y
yum install python-backports-lzma -y
pip3.9 install backports.lzma

• 修改 lzma.py
• vim /usr/local/python3.9/lib/python3.9/lzma.py

#修改前
from _lzma import *
from _lzma import _encode_filter_properties, _decode_filter_properties

#修改后 
try:
    from _lzma import *
    from _lzma import _encode_filter_properties, _decode_filter_properties
except ImportError:
    from backports.lzma import *
    from backports.lzma import _encode_filter_properties, _decode_filter_properties

修复方法二：python-backports-lzma
