Gaussdb T 1.0.2安装遇到AttributeError: module 'platform' has no attribute 'dist'处理方法

在Gaussdb T 1.0.2部署时，若你的Python版本为3.8+,那很有可能会遇到“AttributeError: module ‘platform’ has no attribute ‘dist’”问题，报错示例如下：

[root@gaussdb1 script]# ./gs_preinstall -U omm -G dbgrp -X /opt/clusterconfig.xml 
Traceback (most recent call last):
  File "./gs_preinstall", line 56, in <module>
    from gspylib.common.GaussLog import GaussLog
  File "/opt/software/script/gspylib/common/GaussLog.py", line 21, in <module>
    from gspylib.common.Common import DefaultValue, getstatusoutput
  File "/opt/software/script/gspylib/common/Common.py", line 41, in <module>
    from gspylib.os.gsplatform import g_Platform
  File "/opt/software/script/gspylib/os/gsplatform.py", line 1169, in <module>
    g_Platform = UserPlatform().userPlatform
  File "/opt/software/script/gspylib/os/gsplatform.py", line 1144, in __init__
    distName, _, _ = platform.dist()
AttributeError: module 'platform' has no attribute 'dist'
[root@gaussdb1 script]# 

这是由于Python3.8版本已不支持dist包引起。解决方法为安装python3.7版本。如：3.7.6。简单记录下。
