更改目錄時輸入錯誤

Question

當tring改變目錄時，我總是收到以下錯誤：任何人都可以幫助解決問題以及如何解決這個問題？

代碼片段： -

print "changing dir..." 
print "BUILDDIR: " + BuildDir 
os.chdir(BuildDir) 
print "Done changing dir..." 

錯誤： -

changing dir... 
BUILDDIR: /local/mnt/workspace/username/AU_LINUX_ANDROID_CHO_3.5.04.03.00.003.047_msm8216/

    picked_gerrits = [] 
    File "Main.py", line 126, in RepoSync

很難說沒有能夠再現。嘗試：

'/'.join(map(str.strip, BuildDir.split('/'))) 

如果不是這是google brought me：

import os, re 

_split = re.compile(r'[\0%s]' % re.escape(''.join(
    [os.path.sep, os.path.altsep or '']))) 

def secure_filename(path): 
    return _split.sub('', path) 

print '/%s/' % '/'.join([secure_filename(x) for x in BuildDir.split('/') if x])
