Use PdfReader instead.

这个报错是因为 PyPDF2 库的版本更新了，`PdfFileReader` 已经被废弃，需要使用 `PdfReader` 替换。你可以将代码中的 `PdfFileReader` 替换为 `PdfReader`，如下所示：

import PyPDF2
import chardet

# 打开 PDF 文件
with open('filename.pdf', 'rb') as pdf_file:
    pdf_reader = PyPDF2.PdfReader(pdf_file)

    # 获取 PDF 文件中的所有页面
    pages = len(pdf_reader.pages)

    # 遍历每一页，获取页面的文本内容
    for i in range(pages):
        page = pdf_reader.pages[i]
        text = page.extract_text()

        # 检测编码格式并将文本内容转换成正确的编码格式
        detected_encoding = chardet.detect(text)
        text = text.decode(detected_encoding['encoding']).encode('utf-8')

        # 将文本内容保存到文件中
        with open(f'output_{i}.txt', 'w', encoding='utf-8') as output_file:
            output_file.write(text)

希望这次能够运行成功！
