安装过requests_html库了结果显示没有

一直错误显示

Traceback (most recent call last):
File "C:/Users/14399/Desktop/py/crawler.py", line 1, in
from requests_html import HTMLSession
ModuleNotFoundError: No module named 'requests_html'

from requests_html import HTMLSession
session = HTMLSession()
r = session.get('https://movie.douban.com/subject/1292052/')
print(r.text)

确认安装了么？
用 pip install requests-html
看下输出信息
