直到一切都好。

Then comes this huge error that takes time to copy paste, It was a 1M line of error, can't paste it in here.

我认为问题出在

使用缓存的 scipy-1.6.3.tar.gz (27.2 MB) 安装构建依赖项... \

为此 scipy 安装依赖项以下是出现巨大错误后的警告。

请提及您的python版本
是的，我已经提到了，谢谢。

标签： python python-3.x xcode coremltools

【解决方案1】：

我正在为 python 3.9.x 安装它，请注意它从今天（2021 年 6 月 19 日）起可用于 3.6.x - 3.8.x。将您的 python 版本更改为 3.6.x - 3.8.x。应该可以的。
