【问题描述】
生产环境准备做修改IP操作，虚机模式时发现，使用 ansible 部署 TiDB 2.1.19 在安装 ansible 依赖环境时出现错误 ImportError: No module named setuptools_rust
操作步骤参考 官网文档-ansible 离线部署 ，之前我使用 ansible 安装过 3 版本并未出现问题，而且这还是安装依赖阶段，按理说不应该出错，求解？
尝试如下：
-
尝试过在线安装，同样报错，放弃；
-
pip install --upgrade pip 升级 pip 后，会报 ansible sys.stderr.write(f"ERROR: {exc}") ，放弃；
-
尝试取 github 下载 setuptools-rust 手动 build，发现好像只能用 python3 去build，相关步骤如下,而且官网的步骤 python 依赖的是 python 2.7，所以未继续尝试，放弃；
[tidb@localhost setuptools-rust]$ python3 setup.py install --user Traceback (most recent call last): File "setup.py", line 6, in <module> setup() ...... ...... File "/home/tidb/setuptools-rust/setuptools_rust/utils.py", line 6, in <module> import semantic_version ModuleNotFoundError: No module named 'semantic_version' -
操作系统环境

依据官网步骤执行如下：

感觉我操作并未出错，且之前有成功案例， TIDB 官方已经不维护 ansible 了，是不是官网的操作步骤不适用现在情况了？这种情况如何解决？
