python - 使用子进程从 python 执行时，ssh 不被识别为命令？

Question

这是我的代码 -

import subprocess
import sys

HOST="xyz3511.uhc.com"
# Ports are handled in ~/.ssh/config since we use OpenSSH
COMMAND="uptime"

ssh = subprocess.Popen(["ssh", "%s" % HOST, COMMAND],
                       shell=True,
                       stdout=subprocess.PIPE,
                       stderr=subprocess.PIPE)
result = ssh.stdout.readlines()
if result == []:
    error = ssh.stderr.readlines()
    print (sys.stderr, "ERROR: %s" % error)
else:
    print (result)

这是我遇到的错误-

ERROR: [b"'ssh' is not recognized as an internal or external command,\r\n", b'operable program or batch file.\r\n'].

不确定我在这里做错了什么。另外，我没有提到任何端口。我只想使用子进程并连接到远程服务器，执行一个简单的命令，如 ls。 Python 版本为 3.x。

显然这发生在 python3 中。在此链接中找到解决方法: https://gist.github.com/bortzmeyer/1284249

system32 = os.path.join(os.environ['SystemRoot'], 'SysNative' if platform.architecture()[0] == '32bit' else 'System32')
ssh_path = os.path.join(system32, 'OpenSSH/ssh.exe')
out1, err1 = Popen([ssh_path, "pi@%s"%self.host, "%s"%cmd],
              shell=False,
              stdout=PIPE, 
              stderr=PIPE).communicate()
