看起来它与clang 相关。不过我不完全确定。

错误：error: command 'clang' failed with exit status 1

到目前为止，我已经重新安装了 xcode 和 xcode-select。我也在虚拟环境中运行 python 3.7.9。

您似乎正在安装 pandas v0.23.4，它没有为 macOS 11 预构建的二进制文件（这可能是所有 pandas 版本的情况，现在我正在寻找）。

这意味着您必须从源代码构建 pandas，这需要安装正确的构建依赖项。这些 numpy 弃用警告让我认为您需要旧版本的 numpy（我认为它们指定了最低版本，但没有指定最高版本）。

两个建议：

1. 您能否尝试使用 pandas v0.25.3（1.x 版本之前的最后一个稳定版本）或 1.2.1（当前稳定版本？v0.25 版本删除了一堆旧的 C 代码，这应该有助于避免一些这些错误。
2. 在安装pandas之前，能否安装旧版本的numpy？ 1.13.3 是 0.25.3 发布时所需的最低版本，大约从那里到几个更高的主要版本应该可以工作。
