Django 在windows server 2019运行出错

django 调用函数如下,报错位置如下,报错代码如下。
有知道这个错误的小伙伴帮助出个主意。
电脑已经安装wps,系统是Windows server2019

# 截图保存
def create_save_img(file_path, img_name):
    # 读取excel内容转换为图片
    import pythoncom
    from win32com.client import DispatchEx
    from PIL import ImageGrab

    import os

    file_path = os.path.abspath(file_path)
    pythoncom.CoInitialize()  # excel多线程相关
    excel = DispatchEx("Excel.Application")  # 启动excel

    # del excel #这个地方很重要,杀死excel进程是这个地方起作用

    # excel.Visible = False  # 不显示Excel,而True可视化
    excel.DisplayAlerts = True  # 是否显示警告,关闭系统警告(保存时不会弹出窗口)
    workbook = excel.workbooks.Open(file_path)  # 打开excel
    sheet = workbook.worksheets["Sheet1"]  # 选择sheet
    screen_area = sheet.UsedRange  # 有内容的区域
    screen_area.CopyPicture()  # 复制图片区域
    sheet.Paste()  # 粘贴
    '''
        name = str(uuid.uuid4())  # 重命名唯一值
        image_name = name[:6]
        excel.Selection.ShapeRange.Name = image_name  # 将刚刚选择的Shape重命名,避免与已有图片混淆
    '''
    excel.Selection.ShapeRange.Name = img_name  # 将刚刚选择的Shape重命名,避免与已有图片混淆
    sheet.Shapes(img_name).Copy()  # 选择图片

    img = ImageGrab.grabclipboard()  # 获取剪贴板的图片数据
    img.save(r"D:/static/media/img/" + img_name)
    workbook.Close(False)  # 关闭Excel文件,不保存
    excel.Quit()  # 退出excel
    del excel  # 这个地方很重要,杀死excel进程是这个地方起作用
    pythoncom.CoUninitialize()  # 关闭多线程
    os.remove(file_path)

程序写了备注,报错在函数的
excel = DispatchEx("Excel.Application") # 启动excel
报错内容如下

检查了注册表,注册表中存在 Excel.Application
