我是Flask的初学者，安装时出现此错误。
我的点子版本是20.2.3。
我的python版本是3.9。
我也尝试使用pip install PIL安装Pillow，但仍然无法正常工作。
我正在使用Windows 10。
所以，请您帮我用pip安装Pillow。
答案 0 :(得分：0)
答案不是很清楚，但是显示在“完整输出（172行）”的第一行：
C：\ Users \ Gaming \ AppData \ Local \ Temp \ pip-install-boxgam9w \ pillow \ setup.py：42：RuntimeWarning：Pillow 7.2.0不支持Python 3.9，并且不提供预构建的Windows二进制文件。我们不建议在Windows上从源代码构建。
枕头8.0.0将于下周发布，并将支持Python 3.9。
