试图重命名OneDrive的文件时许可

Question

当我运行加密文件的代码时，我会收到以下错误：

<_io.TextIOWrapper name='C:/Users/depen/OneDrive/Documents/PNG_transparency_demonstration_1 >(2).png' mode='r' encoding='cp1252'>
read
encrypting
encrypted
encrypted file saved
Traceback (most recent call last):
  File "c:\Users\depen\OneDrive\Documents\python\timer\encrypt.py", line 93, in <module>
    encrypt(fpath)
  File "c:\Users\depen\OneDrive\Documents\python\timer\encrypt.py", line 67, in encrypt
    os.rename(file_fpath, file_fpath + ".encrypted")
PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:/Users/depen/OneDrive/Documents/PNG_transparency_demonstration_1 (2).png' -> 'C:/Users/depen/OneDrive/Documents/PNG_transparency_demonstration_1 (2).png.encrypted'

以下是我的代码：

fernet = AES(key)

def encrypt(file_path):
    #start a timer
    start = time.time()

    def read_in_chunks(file_object, chunk_size= 52428800):
        while True:
            data = file_object.read(chunk_size)
            if not data:
                break
            yield data


    with open(file_path, "rb") as f:
        for piece in read_in_chunks(f):
            data = fernet.encrypt(randbytes(16), piece, randbytes(16))
            currenttime = time.time()
            print(currenttime - start)
            with open (file_path + ".enc", "ab") as f:
                f.write(data)
                f.close()
    
    with open("filenames.txt", "a") as file:
        file.write(file_path + "\n")
        file.close()
    #end the timer
    end = time.time()
    print ("Time taken to encrypt   `: " + str(end - start))
    os.remove(file_path)

代码确实加密文件，但剂量不添加。将.centpypted添加到文件名的末尾。

您会遇到此错误，因为您正在使用OneDrive目录。 OneDrive正在尝试同步文件，因此创建文件后，他将尝试上传文件。

尝试从OneDrive不使用的另一个目录执行您的代码

The process cannot access the file because it is being used by another process: 'C:/Users/depen/OneDrive/Documents/PNG_transparency_demonstration_1 (2).png' -> 'C:/Users/depen/OneDrive/Documents/PNG_transparency_demonstration_1 (2).png.encrypted'
