用pycharm爬虫,写完代码运行发现parsel模块不能调用？

用pycharm爬虫,写完代码运行发现parsel模块不能调用（TypeError: 'module' object is not callable）？用pip安装了几次，都是成功，用terminal安装，提示:



Requirement already satisfied: parsel in ./venv/lib/python3.8/site-packages (1.6.0)

# 1.确定url地址
url = "https://nba.hupu.com/stats/players"

# 2.发送网络请求 requests(js\html\css)
response = requests.get(url=url)
html_data = response.text
#print(html_data)

# 3.数据解析（筛选数据）
# 3.1 转换数据类型

selector = parsel.selector(html_data)
改成
selector = parsel.Selector(html_data)
Selector的S是大写
