在使用 pip 安装 POPPY 0.3 以及所需的所有资源时，我收到了几个关于 Astropy 弃用警告和 pysynphot 的警告，我不太了解。在失败前的最后几行，Traceback 显示错误在 astropy setup_helpers 文件中。下一行说 KeyError 'pytest'。有没有人经历过这种情况或对我的情况有任何见解？

这是命令提示符的东西：

这看起来像是几件事的结合：

1) 它看起来像是 poppy 正在使用的 Astropy 构建代码中的一个小错误。

2) 看起来罂粟尚未与最新版本的 Astropy (v0.4) 完全兼容，因此在此期间，如果不出意外，您可以尝试降级到 Astropy v0.3.2。

同时，您应该就此类问题联系包的作者。
