Did you mean: '_save'?怎么解决

将 writer.save() 改为 writer.close() 即可解决该问题。XlsxWriter 对象没有 save() 方法，需要使用 close() 方法来关闭文件。修改后的代码如下：

import os
import pandas as pd

folder_path = '/path/to/folder'  # 路径
files = os.listdir(folder_path)  # 获取路径下所有文件
excel_files = [f for f in files if f.endswith('.xlsx')]  # 筛选出所有后缀为.xlsx的文件
data_frames = []  # 存储所有读取到的excel文件
for file in excel_files:
    file_path = os.path.join(folder_path, file)  # 获取文件的绝对路径
    data_frames.append(pd.read_excel(file_path))

writer = pd.ExcelWriter('/path/to/output/file.xlsx', engine='xlsxwriter')  # 创建一个ExcelWriter对象
all_data = pd.concat(data_frames, ignore_index=True)  # 合并所有dataframe
all_data.to_excel(writer, index=False)  # 将合并后的dataframe写入同一个excel文件中
writer.close()  # 关闭ExcelWriter对象，保存文件
