【问题描述】：
我正在尝试使用 pysftp 通过 sftp 将文件从本地机器发送到服务器
当我使用命令行登录服务器时：
sftp -o port=111 user_name@host
然后执行pwd 我得到/ 作为当前位置
所以我想在pysftp 中做同样的事情：
import pysftp
cnopts = pysftp.CnOpts()
cnopts.hostkeys = None
with pysftp.Connection("host", username="user_name", password="password", port=111, cnopts=cnopts) as sftp:
print(sftp.pwd)
sftp.put(local_file, sftp.pwd)
但我收到错误IOError: [Errno 13] Permission denied
虽然，我可以在命令行中使用相同的凭据和像 FileZilla 这样的 ftp 客户端进行 sftp
这里是完整的错误跟踪：

完整的堆栈跟踪会很有帮助。知道它是一个 IOError 并不能真正帮助了解 哪个 操作失败，以及它是本地表示的远程异常还是本地系统调用失败。
