关闭文件时出错 [英] error moving file with shutil

问题描述

我正在尝试创建一个简单的函数，该函数查找以某个字符串开头的文件，然后将其移动到新目录，但是我不断从shutil中收到以下类型的错误： IOError：[Errno 2]没有此类文件或目录：'18 -1.pdf'，即使文件存在。

I am trying to create a simple function that finds files that begin with a certain string and then move them to a new directory but I keep getting the following kinds of errors from shutil "IOError: [Errno 2] No such file or directory: '18-1.pdf'", even though the file exists.

import os
import shutil
def mv_files(current_dir,start):
    # start of file name
    start = str(start)
    # new directory ro move files in to
    new_dir = current_dir + "/chap_"+ start
    for _file in os.listdir(current_dir):
        # if directory does not exist, create it
        if not os.path.exists(new_dir):
                os.mkdir(new_dir)
        # find files beginning with start and move them to new dir
        if _file.startswith(start):
            shutil.move(_file, new_dir)

我不正确地使用shutil吗？

Am I using shutil incorrectly?

正确的代码：

import os
import shutil
def mv_files(current_dir,start):
    # start of file name
    start = str(start)
    # new directory ro move files in to
    new_dir = current_dir + "/chap_" + start
    for _file in os.listdir(current_dir):
        # if directory does not exist, create it
        if not os.path.exists(new_dir):
            os.mkdir(new_dir)
       # find files beginning with start and move them to new dir
        if _file.startswith(start):
            shutil.move(current_dir+"/"+_file, new_dir)

推荐答案

好像你不是提供 shutil.move 的完整路径。尝试：

It looks like you aren't giving the full path to shutil.move. Try:

if _file.startswith(start):
    shutil.move(os.path.abspath(_file), new_dir)

如果失败，请尝试打印 _file 和 new_dir 以及 os.getcwd（）的结果，并将它们添加到您的答案中。

If that fails, try printing _file, and new_dir along with the result of os.getcwd() and adding them to your answer.
