【已解决】 Could not build wheels for cryptography which use PEP 517 and cannot be installed directly

anaconda prompt安装scrapy库中遇到的问题

Could not build wheels for cryptography which use PEP 517 and cannot be installed directly

我的总结：

pip install --only-binary :all: cryptography
pip install scrapy -i https://pypi.tuna.tsinghua.edu.cn/simple

里面scrapy是要装的库名

参考以下文本的
