推荐答案

pip install PIL --allow-external PIL --allow-unverified PIL

这是由于新版Pip中的更改所致.运行pip --version，我敢打赌您正在运行 1.5 .请在此处中查看更改日志.这种新的默认行为增强了安全性.在PIL的情况下，您要安装的文件实际上来自 effbot.org (因此为--allow-external)，而PyPi没有校验和以确保有效性(因此为--allow-unverified).

This is due to changes in the new version of Pip. Run pip --version and I'm willing to bet you are running 1.5. See the changelog here. This new default behavior enhances security. In PIL's case, the file you are installing actually comes from effbot.org (thus --allow-external) and PyPi doesn't have a checksum to guarantee validity (thus --allow-unverified).

此外，您可以考虑将枕头替换为PIL.

Also, you might consider using the Pillow replacement to PIL.
