Python 根本没法安装 curl_cffi 怎么回事？

python 新手，尝试 pip install curl_cffi ，报错：

Could not find a version that satisfies the requirement curl_cffi (from versions: ) No matching distribution found for curl_cffi 

python --version 显示：Python 2.7.17

然后尝试 pip3 install curl_cffi ，安装成功了，然后运行 test.py：

from curl_cffi import requests r = requests.get("https://tls.browserleaks.com/json", impersOnate="chrome101") print(r.json()) 

python3 test.py 报错如下：

Traceback (most recent call last): File "test.py", line 1, in <module> from curl_cffi import requests ImportError: cannot import name 'requests' 

python3 --version 显示：Python 3.6.9

请问这该怎么解决？
