无法在Jenkins中将Python脚本作为作业执行

Question

我试图执行一个Python脚本，该脚本在Jenkins中使用selenium作为作业，但出现以下错误

    17:45:55 Started by timer
    17:45:55 Running as SYSTEM
    17:45:55 Building in workspace /Users/it/.jenkins/workspace/crawler
    17:45:55 [crawler] $ /bin/sh -xe /var/folders/t2/sk1vw_mn7mz7ncjw75lzh7r40000gn/T/jenkins8733501635454851045.sh
    17:45:55 + export PYTHONPATH=/Users/it
    17:45:55 + PYTHONPATH=/Users/it
    17:45:55 + cd /Users/it
    17:45:55 + python3 crawler_continious_execution_1.py
    17:45:56 Traceback (most recent call last):
    17:45:56   File "crawler_continious_execution_1.py", line 1, in <module>
    17:45:56     from selenium import webdriver 
    17:45:56 ModuleNotFoundError: No module named 'selenium'
    17:45:56 Build step 'Execute shell' marked build as failure
    17:45:56 Finished: FAILURE

即使我已经安装了SELENIUM模块

it@rgits-Mac-mini ~ % pip3 install selenium           
Requirement already satisfied: selenium in /usr/local/lib/python3.7/site-packages (3.141.0)
Requirement already satisfied: urllib3 in /usr/local/lib/python3.7/site-packages (from selenium) (1.25.8)
it@rgits-Mac-mini ~ % 

我已经搜索了谷歌和其他堆栈线程，并按以下方式进行了搜索，但没有一个有效，并且给出了以下结果。有人能帮我解决这个问题吗。

我在Jenkins安装上创建的用户是Jenkins_admin，Mac用户是“IT”

尝试了许多方法，但无法以JENKINS用户的身份安装SELENIUM。正如您所见，selenium已安装，但通过Jenkins显示“模块未找到错误”，如果有人能在这方面提供帮助，将非常有帮助。
