Error handling during Python project running process

1. Background

Due to the recent localization transformation of the OS, the Python project in the centos 6.5 environment needs to be migrated to the BCLinux 8.6 environment to run. However, there are some errors during the running process. They are recorded here for reference by latecomers.

Live environment: Python3.6.3----->Target: python3.6.8

Resource links: backports-lzma , PyPI Tsinghua mirror , campus pypi source , stackoverflow , Python Package Index

2. Error handling:

1）报错：pandas/compat/init.py:85: UserWarning: Could not import the lzma module.

This is because the migrated environment lacks dependencies and the backports.lzma module. Execute:

yum install python-backports-lzma xz-devel gcc -y
Wget https://files.pythonhosted.org/packages/21/0f/1a9990233076d48aa2084100ba289ca162975e73a688f3a56c0ee2bb441a/backports.lzma-0.0.14.tar.gz
tar -xzf backports.lzma-0.0.14.tar.gz 
python3 setup.py install  #依赖gcc，输出如下
