Python程序启动报：ModuleNotFoundError: No module named ‘_lzma‘

解决方案：

File "/usr/local/lib/python3.7/lzma.py", line 27, in
    from _lzma import *
ModuleNotFoundError: No module named '_lzma'

yum install xz-devel

yum install python-backports-lzma

pip install backports.lzma

# 然后找到    lzma.py  文件，vi命令去改写它

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
