【解决】Python 删除只读文件/文件夹报错：[WinError 5] 拒绝访问。

1. 按

有时候我们使用shutil.rmtree()、os.rmdir()、os.remove()删除文件时会报[WinError 5] 拒绝访问的错误：
如使用os.remove()删除当前文件夹下的'PackageCache\\[email protected]\\Tests\\Editor.meta'时提示

[WinError 5] 拒绝访问。: ‘PackageCache\[email protected]\Tests\Editor.meta’

这个时候我们可以让Python运行cmd命令强制删除此文件：

import os
os.system('del "PackageCache\[email protected]\Tests\Editor.meta" /F')

关于使用CMD命令删除文件或文件夹，可以参考：Windows CMD删除文件或文件夹命令帮助

2. 实际运用

import os
import shutil


dirs = ['.idea', '.vs', 'Logs', 'obj']
files = ['.sln', '.csproj']

dirsCnt = 0
filesCnt = 0

def delWithCmd(path):
    try:
        if os.path.isfile(path):
            cmd = 'del "'+ path + '" /F'
            print(cmd)
            os.system(cmd)
    except Exception as e:
        print(e)


def deleteDir(dirPath):
    global dirsCnt
    global filesCnt
    for root, dirs, files in os.walk(dirPath, topdown=False):
        for name in files:
            try:
                filesCnt += 1
                filePath = os.path.join(root, name)
                print('file deleted', filesCnt, filePath)
                os.remove(filePath)
            except Exception as e:
                print(e)
                delWithCmd(filePath)
        for name in dirs:
            try:
                os.rmdir(os.path.join(root, name))
                dirsCnt += 1
            except Exception as e:
                print(e)
    os.rmdir(dirPath)

def delDir(dirPath):
    global dirsCnt
    shutil.rmtree(dirPath)
    dirsCnt += 1
    print('dir deleted', dirsCnt, dirPath)


def delFile(filePath):
    global filesCnt
    os.remove(filePath)
    filesCnt += 1
    print('file deleted', filesCnt, filePath)

    try:
        if os.path.isfile(path):
            delFile(path)
        elif os.path.isdir(path):
            deleteDir(path)
    except Exception as e:
        print(e)

for proj in os.listdir():
    if not os.path.isdir(proj):
        continue
    os.chdir(proj)
    print(os.getcwd())
    for p in os.listdir():
        if os.path.isdir(p) and p in dirs:
            delete(p)
        elif os.path.isfile(p) and os.path.splitext(p)[1] in files:
            delete(p)
    libPath = 'Library'
    if os.path.exists(libPath) and os.path.isdir(libPath):
        os.chdir(libPath)
        for p in os.listdir():
            if p == 'LastSceneManagerSetup.txt':
                continue
            delete(p)
        os.chdir('..')
    os.chdir('..')
