Question

我正在尝试从目录树中删除旧的SVN文件。 shutil.rmtree和os.unlink提升WindowsError，因为该脚本无权删除它们。我怎么能解决这个问题？

这是脚本：

# Delete all files of a certain type from a direcotry

import os
import shutil

dir = "c:\\"

verbosity = 0;

def printCleanMsg(dir_path):
    if verbosity:
        print "Cleaning %s\n" % dir_path

def cleandir(dir_path):
    printCleanMsg(dir_path)
    toDelete = []
    dirwalk = os.walk(dir_path)
    for root, dirs, files in dirwalk:
        printCleanMsg(root)
        toDelete.extend([root + os.sep + dir for dir in dirs if '.svn' == dir])
        toDelete.extend([root + os.sep + file for file in files if 'svn' in file])

    print "Items to be deleted:"
    for candidate in toDelete:
        print candidate
    print "Delete all %d items? [y|n]" % len(toDelete)

    choice = raw_input()

    if choice == 'y':
        deleted = 0
        for filedir in toDelete:
            if os.path.exists(filedir): # could have been deleted already by rmtree
                try:
                    if os.path.isdir(filedir):
                        shutil.rmtree(filedir)
                    else:
                        os.unlink(filedir)
                    deleted += 1
                except WindowsError:
                    print "WindowsError: Couldn't delete '%s'" % filedir

    print "\nDeleted %d/%d files." % (deleted, len(toDelete))
    exit()

if __name__ == "__main__":
    cleandir(dir)

无法删除任何单个文件。我做错了什么？

Answer 1

Subversion通常会使所有.svn目录（以及其中的所有内容）都受到保护。可能在删除文件之前必须先删除写保护。

我不确定如何使用Windows做到最好，但您应该能够将os.chmod()与stat.S_IWRITE标志一起使用。可能你必须遍历.svn目录中的所有文件，并使它们都可以单独写入。

要递归删除所有.svn我使用此脚本。可能会帮助别人。

import os, shutil, stat

def del_evenReadonly(action, name, exc):
    os.chmod(name, stat.S_IWRITE)
    os.remove(name)

for root, subFolders, files in os.walk(os.getcwd()):
    if '.svn' in subFolders:
      shutil.rmtree(root+'\.svn',onerror=del_evenReadonly)

删除旧SVN文件的Python脚本缺少权限
