PermissionError:[WinError 32]该进程无法访问文件，因为它正在被另一个进程使用 [英] PermissionError: [WinError 32] The process cannot access the file because it is being used by another process

问题描述

我的代码用于一个脚本，该脚本查看一个文件夹并删除分辨率为1920x1080的图像.我遇到的问题是我的代码运行时；

My code is for a script that looks at a folder and deletes images that are under a resolution of 1920x1080. The problem I am having is that when my code runs;

import os
from PIL import Image

while True:    
    img_dir = r"C:\Users\Harold\Google Drive\wallpapers"
    for filename in os.listdir(img_dir):
        filepath = os.path.join(img_dir, filename)
        im = Image.open(filepath)
        x, y = im.size
        totalsize = x*y
        if totalsize < 2073600:
            os.remove(filepath)

我收到此错误消息:

Traceback (most recent call last):
  File "C:\Users\Harold\Desktop\imagefilter.py", line 12, in <module>
    os.remove(filepath)
PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\\Users\\Harold\\Google Drive\\wallpapers\\Car - ABT Audi RS6-R [OS] [1600x1060].jpg'

只需确认一下，Python是我的计算机上运行的唯一程序.是什么导致此问题，我该如何解决?

Just to confirm, Python is the only program running on my computer. What is causing this problem and how do I fix it?

推荐答案

您的进程就是打开文件的过程(通过im仍然存在).您需要先关闭它，然后再删除它.

Your process is the one that has the file open (via im still existing). You need to close it first before deleting it.

我不知道PIL是否支持with上下文，但是是否支持:

I don't know if PIL supports with contexts, but if it did:

import os
from PIL import Image

while True:    
    img_dir = r"C:\Users\Harold\Google Drive\wallpapers"
    for filename in os.listdir(img_dir):
        filepath = os.path.join(img_dir, filename)
        with Image.open(filepath) as im:
            x, y = im.size
        totalsize = x*y
        if totalsize < 2073600:
            os.remove(filepath)

这将确保您在进入os.remove之前删除im(并关闭文件).

This will make sure to delete im (and close the file) before you get to os.remove.

如果没有，您可能要签出Pillow，因为PIL的开发已经停滞了.

If it doesn't you might want to check out Pillow, since PIL development is pretty much dead.
