重新执行
执行 pip install pyhanlp 后仍然会有报错
WARNING: You are using pip version 21.2.2; however, version 21.2.4 is available.
You should consider upgrading via the 'c:\python39\python.exe -m pip install --upgrade pip' command.
再次执行
先更新pip
c:\python39\python.exe -m pip install --upgrade pip
再执行
pip install pyhanlp
又出报错我

处理步骤1：
先打开python看看自己的python是什么版本的，多少位的。
Python 3.9.6 64 bit 
处理步骤2：
去https://www.lfd.uci.edu/~gohlke/pythonlibs/找到对应版本的whl文件
处理步骤3：
下载对应的whl文件后，在cmd下进入whl所在的文件夹
C:\Python39\whl
C:\Python39\whl>pip install JPype1-1.3.0-cp39-cp39-win_amd64.whl
