我试过不行
pip install C:\Users\star\Desktop Twisted-20.3.0-cp39-cp39-win_amd64.whl
之后运行pip install --target=D:\Program\Python\Scripts scrapy
提示Microsoft Visual C++ 14.0 is required
我安装Microsoft Visual C++ Build Tools
再运行pip install --target=D:\Program\Python\Scripts scrapy
就变成这样了

安装build tools或者vs2019是解决方法之一，但可能要配置好build tools或者vs的环境变量，如果你没有安装多个Python环境，那pip命令就没必要加其他参数，直接pip install scrapy就行了。就算你安装了多个Python环境，你只要进入你需要安装scrapy的环境的Scripts目录，在那里按住shift加右键选打开命令窗口，直接pip install scrapy就可以了 python3.8以及3.9安装scrapy报错的处理方法
