其他信息

看报错估计是下载下来的图片格式问题，或者img2pdf库的问题（？

[hect0x7]

我使用你的代码直接运行成功了，没有报错

[hect0x7]

你看看下载下来的图片是否有空白图

[BrandenXia]

我看了一下，图片都不是空的，检查了一下包的版本，也都是最新的

[BrandenXia]

我等会试一下直接在repl里用img2pdf处理能不能复现

[BrandenXia]

好像是img2pdf库的问题，我直接用PIL的Image.open，输入图片路径不会有问题，img2pdf是读成ByteIO再放到PIL的Image.open的，这个库也很久没维护了，可能在mac上不兼容新版本的PIL了？
