它在 CentOS Linux 版本 7.6.1810（核心）系統上運行 Python 2.7.5。我沒有太多使用 Python 的經驗。但我已經查看了之前的一些問題/示例，但無法弄清楚如何繼續處理這個問題。我無法從 Python 腳本運行 Linux ssh 命令。但是，當我運行 Linux echo 命令時，我得到了預期的結果。我將提供代碼和兩個輸出：#!/bin/pythonimport sysimport subprocesstunnelUser='testuser'localIP = []localPort = []remoteIP = []remotePort = []x = 0vfile=open('/home/'+tunnelUser+'/development/scripts/port-dummy-data','rt')for line in vfile:    columns = line.split(',')    localIP.append(columns[0])    localPort.append(columns[1])    remoteIP.append(columns[2])    remotePort.append(columns[3])    sshCommand = " -f -N "+tunnelUser+"@"+localIP[x]+" -R "+localPort[x]\        +":"+remoteIP[x]+":"+remotePort[x]    subprocess.Popen(['/bin/ssh', sshCommand])    # subprocess.Popen(['/bin/echo', sshCommand])    x=x+1sys.stdout.close()產生以下負面結果：prompt > ./create-tunnels.py prompt > ssh: Could not resolve hostname localhost -r 8080:192.168.1.3:8080: Name or service not knownssh: Could not resolve hostname localhost -r 8090:192.168.1.11:8090: Name or service not knownssh: Could not resolve hostname localhost -r 8081:192.168.1.5:8081: Name or service not knownssh: Could not resolve hostname localhost -r 8085:192.168.1.9:8085: Name or service not knownssh: Could not resolve hostname localhost -r 8095:192.168.1.12:8095: Name or service not known然而，當我“注釋掉” ssh 并“取消注釋” echo 時，我得到了預期的結果：prompt > ./create-tunnels.py  -f -N testuser@localhost -R 8080:192.168.1.3:8080 -f -N testuser@localhost -R 8081:192.168.1.5:8081 -f -N testuser@localhost -R 8085:192.168.1.9:8085 -f -N testuser@localhost -R 8090:192.168.1.11:8090 -f -N testuser@localhost -R 8095:192.168.1.12:8095我相信由于缺乏 Python 經驗，我錯過了一些簡單的東西。任何幫助，將不勝感激。
