Python工具logChecker：脚本运行正常，pip安装后CLI执行重复两次求助

我开发了一款用于日志对比的Python工具logChecker，直接以Python脚本形式运行时一切正常：

$ python3 src/logChecker/logChecker.py -pre logs_pre/ -post logs_pos/ -tf templ/
##### Successfully Loaded Templates from folder templ/ #####
##### Successfully Loaded Templates from folder templ/ #####
##### Logs Loaded Successfully from folder logs_pre/ #####
##### Logs Loaded Successfully from folder logs_pos/ #####
0 0 sh_rtr_opsf_op_db.template agg01.cpe_rx.json
1 0 sh_rtr_bgp_neigh.template agg01.cpe_rx.json
2 0 sh_rtr_rt_tbl_summ.template agg01.cpe_rx.json
3 0 sh_rtr_ospf_neigh.template agg01.cpe_rx.json
0 0 sh_rtr_opsf_op_db.template agg01.cpe_rx.json
1 0 sh_rtr_bgp_neigh.template agg01.cpe_rx.json
2 0 sh_rtr_rt_tbl_summ.template agg01.cpe_rx.json
3 0 sh_rtr_ospf_neigh.template agg01.cpe_rx.json

# 1 sh_rtr_bgp_neigh.template
# 2 sh_rtr_rt_tbl_summ.template
# 3 sh_rtr_ospf_neigh.template

但通过pip3 install logChecker安装后，CLI调用工具会执行两次：

问题仅出现在pip安装后的CLI调用场景，直接跑脚本或内部调用均正常。已检查setup.py未发现明显问题，以下是排查方向和解决思路：

• 检查setup.py的entry_points配置：确认console_scripts是否重复定义，或同时使用了console_scripts和scripts字段（两者都会生成CLI入口，可能导致重复触发）。
• 排查主脚本的执行逻辑：检查logChecker.py中是否有if __name__ == "__main__":块之外的直接执行代码。通过entry_points调用时模块会被导入，若模块顶层有执行代码，会和main函数的调用重复执行；同时确认main函数是否被多次调用。
• 查看CLI入口脚本内容：用which logChecker找到命令路径，查看生成的脚本，确认是否存在两次调用main函数的逻辑。
• 验证安装环境：检查是否存在多版本重复安装，或系统中多个bin目录下存在同名脚本，导致调用时触发两次。
• 隔离依赖干扰：在干净的虚拟环境中安装测试，排除textfsm、ttp等依赖的初始化逻辑可能带来的间接触发问题。
