我按照网课教程上写的代码，在我电脑上运行就出错，是什么原因？

def use_bar():
    from pptx import Presentation
    from pptx.chart.data import CategoryChartData
    from pptx.enum.chart import XL_CHART_TYPE
    from pptx.util import Inches
    ppt = Presentation()
    slide = ppt.slides.add_slide(ppt.slide_layouts[6])
    # 封装图表数据
    char_data = CategoryChartData()
    # 分组数据
    char_data.categories = ['第一季度', '第二季度', '第三季度', '第四季度']
    # 具体数据
    char_data.add_series('series', (19, 21, 16))
    x = y = Inches(2)
    width = Inches(6)
    height = Inches(4.5)

    # 绘制图表
    # slide.shapes.add_chart(XL_CHART_TYPE.COlUMN_CLUSTERED, x, y, width, height, char_data)
    slide.shapes.add_chart(XL_CHART_TYPE.COlUMN_CLUSTERED)
    ppt.save('./created data/29_绘制图纸条图.pptx')


if __name__ == '__main__':
    use_bar()

XL_CHART_TYPE这个类无COlUMN_CLUSTERE这个方法在第20行。

XL_CHART_TYPE这个类无COlUMN_CLUSTERE这个方法在第20行。可能是XL_CHART_TYPE版本和书上不一致，库中的函数名称可能有变化
