Use PdfReader instead. 要怎么处理

这个错误是因为 PyPDF2 库在 3.0.0 版本中移除了 `PdfFileReader`，使用了 `PdfReader` 代替。因此，你需要将你的代码中所有使用 `PdfFileReader` 的地方改为使用 `PdfReader`。具体来说，你可以按照以下步骤进行修改：

1. 首先在你的代码中找到所有使用 `PdfFileReader` 的地方。

2. 将 `PdfFileReader` 改为 `PdfReader`。

3. 重新运行代码，检查是否还存在其他错误。

以下是修改后的代码：

import os
import PyPDF2

def extract_references(filepath):
    references = []
    with open(filepath, 'rb') as f:
        pdf = PyPDF2.PdfReader(f)  # 将 PdfFileReader 改为 PdfReader
        for page in pdf.pages:
            text = page.extract_text()
            if text:
                lines = text.split('\n')
                for line in lines:
                    if line.startswith('[') and ']' in line:
                        references.append(line)
    return references

def extract_references_from_folder(folderpath):
    references = []
    for filename in os.listdir(folderpath):
        if filename.endswith('.pdf'):
            filepath = os.path.join(folderpath, filename)
            references.append({
                "filename": filename,
                "references": extract_references(filepath)
            })
    return references

references = extract_references_from_folder(r"C:\Users\86183\PycharmProjects\0609\1979-2010")
print(references)

注意，在使用 `PdfReader` 时，需要将打开文件的模式从 `'r'` 改为 `'rb'`，即使用二进制模式打开文件，以避免出现 `TypeError: 'str' does not support the buffer interface` 错误。
