我正在尝试识别目录中最新的和第二个最新的文件。这是我打算使用的代码:
CONFIGS = "/Users/root/dev/config-files/"
allConfigs = sorted(os.listdir(CONFIGS), key=os.path.getctime)
t1 = "%s/%s" % (CONFIGS, allConfigs[-1])
t2 = "%s/%s" % (CONFIGS, allConfigs[-2])
我遇到了这个错误,我不知道为什么:

>>> import os
>>> CONFIGS = "/Users/root/dev/config-files/"
>>> allConfigs = sorted(os.listdir(CONFIGS), key=os.path.getctime)
Traceback (most recent call last):

return os.stat(filename).st_ctime
OSError: [Errno 2] No such file or directory: 'newest.txt'

有人有什么想法吗?
