Paramiko "TypeError: 'NoneType' object is not callable" at the end of a script that execute command on the server
Paramiko "TypeError: 'NoneType' object is not callable" at the end of a script that execute command on the server
我正在编写一个脚本来在 EC2 实例中执行命令，然后再回来。为此，我正在使用 Paramiko。我的脚本是这样的：
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('<hostname>', username='<username>', password='<password>')
print('connected')
stdin, stdout, stderr = ssh.exec_command("ls -lah")
ssh.close()
print('done')
我得到的轨迹是：
connected
done
Exception ignored in: <function BufferedFile.__del__ at 0x7fa5de814950>
Traceback (most recent call last):

TypeError: 'NoneType' object is not callable
我用来登录的命令是：
ssh -o PubkeyAuthentication=no -l <username> <hostname>
谁能告诉我我做错了什么？
在关闭 SSH 连接之前，您没有等待命令完成。
当 Python 垃圾收集 stdin、stdout 和 stderr 时，Paramiko 崩溃，因为它不希望连接关闭。
