Answer 1

SFTPClient.get的第二个参数是本地文件的路径。尽管您似乎将路径传递到目录。

此外，您不应在SFTP路径上使用os.path.join。 os.path.join用于本地路径。 SFTP始终使用正斜杠，而os.path.join使用本地特定于操作系统的分隔符（Windows上为反斜杠）。

sftp.get(path + '/' + file, os.path.join('E:\InsightImport\CSV_EXTRACT', file))

Python Paramiko，PermissionError：[Errno 13]从远程服务器获取文件时，权限被拒绝
