推荐答案

SFTPClient.get 是本地文件的路径.虽然您似乎传递了一个目录的路径.

The second argument to SFTPClient.get is a path to a local file. While you seem to pass a path to a directory.

此外，您不应在 SFTP 路径上使用 os.path.join.os.path.join 用于 local 路径.SFTP 总是使用 forward 斜杠，而 os.path.join 使用本地操作系统特定的分隔符(Windows 上的 back 斜杠).

Also, you should not use os.path.join on SFTP paths. The os.path.join is for local paths. SFTP always uses forward slashes, while os.path.join uses local OS-specific separators (back slashes on Windows).

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

(或者你可以使用 PosixPath)
