我有一段当前在终端中运行的代码，但是我要自动化它，并使用子进程从python运行这个命令。目标是为ibrestapi启动一个java服务器进行连接。
这些是我通常放在mac终端上的命令。。。

cd /Users/emmanuel/Documents/Sigma-IB-API/clientportal.gw/

为了改变我放进去的目录

bin/run.sh root/conf.yaml

这是我想要的输出。。。

cd /Users/emmanuel/Documents/Sigma-IB-API/clientportal.gw/
emmanuel@MacServer clientportal.gw % bin/run.sh root/conf.yaml
running  
 runtime path : root:dist/ibgroup.web.core.iblink.router.clientportal.gw.jar:build/lib/runtime/*
 verticle     : 
 -> mount demo on /demo
Java Version: 1.8.0_271

相反，当我使用子进程将其放入python中时，并没有得到期望的结果。这是把。。。

import subprocess

subprocess.Popen("bin/run.sh root/conf.yaml", cwd="/Users/emmanuel/Documents/Sigma-IB-API/clientportal.gw/")

这是我收到的但我不想要的结果

Traceback (most recent call last): File "/Users/emmanuel/Documents/Selenium/sub.py", line 3, in <module> subprocess.Popen("bin/run.sh root/conf.yaml", cwd="/Users/emmanuel/Documents/Sigma-IB-API/clientportal.gw/") File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/subprocess.py", line 947, in init self._execute_child(args, executable, preexec_fn, close_fds, File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/subprocess.py", line 1819, in _execute_child raise child_exception_type(errno_num, err_msg, err_filename) –File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/subprocess.py", line 947, in init –

在我完成这个过程之后，我需要java服务器保持运行，以便我可以使用它
