“yum clean all”会删除符号链接吗？

Question

我正在运行融合升级剧本来升级版本。我的操作系统是 RHEL 7，我已经安装了 Python 3.9 并从 /usr/bin 目录创建了到它的符号链接。

运行合流剧本时，它有一个任务，yum-clean-all后面跟着以下任务

• 自定义 Java 安装
• 安装Java
• ...
• ...
• 安装点子
• 升级点
• 安装 pip 包

该剧本在安装时失败pip packages，之后 ansible 不可用。

收到此错误 -

ansible --version

Traceback (most recent call last):
  File "/usr/local/bin/ansible", line 34, in <module>
    from ansible import context
ModuleNotFoundError: No module named 'ansible'

此外，此时也缺少从 /usr/bin 到 python3 的符号链接。

在 中/var/log/yum.log，我在我的剧本失败时看到了以下内容

Jan 04 14:50:44 Installed: python3-setuptools-39.2.0-10.el7.noarch
Jan 04 14:50:44 Installed: python3-pip-9.0.3-8.el7.noarch
Jan 04 14:50:44 Installed: python3-3.6.8-21.el7_9.x86_64
Jan 04 14:50:46 Installed: python3-libs-3.6.8-21.el7_9.x86_64

因此，我怀疑yum clean all删除了这些链接，但无法找到任何证实这一怀疑的内容。

所以，问题是 - 是否yum clean all删除符号链接。有相关文件吗？

如果这不是原因，我需要更深入地挖掘以找出发生了什么

感谢任何指点
