这个错误提示说明 `openpyxl` 库中的 `ReadOnlyWorksheet` 类没有实现 `iter_cols` 方法。你可以使用 `worksheet.columns` 属性来获取指定列的数据，然后使用列表推导式获取单元格的值，如下所示：

import openpyxl
from wordcloud import WordCloud

# 打开Excel文件
workbook = openpyxl.load_workbook('shu_ju.xlsx', read_only=True)

# 获取第一个工作表
worksheet = workbook[workbook.sheetnames[0]]

# 获取第一列数据
column_data = [cell.value for row in worksheet.iter_rows(values_only=True) for cell in row if cell.column == 1]

# 将列表转换为字符串
text = ' '.join(str(cell) for cell in column_data)

# 创建 WordCloud 对象
wordcloud = WordCloud(width=800, height=800, background_color='white', max_words=200, contour_width=3, contour_color='steelblue')

# 生成云图
wordcloud.generate(text)

# 保存云图到文件
wordcloud.to_file('yuntu.png')

这样你应该就可以成功读取 Excel 文件并生成词云了。
