So I was trying to archive a .rar file using rarfile library in Python, but it keeps saying "failed to open". Am using Mac OS X El Capitan, python 2.7. Any help would be appreciated, thanks.

原始代码:

rf = RarFile('test.rar')
rf.extractall()

错误信息:

File "Test.py", line 271, in <module>
rf.extractall()

File "/Users/user/Library/Python/2.7/lib/python/site-packages/rarfile.py", line 679, in extractall
self._extract(fnlist, path, pwd)

File "/Users/user/Library/Python/2.7/lib/python/site-packages/rarfile.py", line 1238, in _extract
check_returncode(p, output)

File "/Users/user/Library/Python/2.7/lib/python/site-packages/rarfile.py", line 1961, in check_returncode
raise exc(msg)

rarfile.RarUnknownError: Unknown exit code [1]: bsdtar: Error opening archive: Failed to open '--'
