我正在学习数据分析课程，我目前正在尝试在 macOS 终端上下载 pandas，但这让我很难过。我已经尝试了从下载自制软件到删除旧文件的所有方法，但仍然没有任何帮助，希望有人能有所帮助！以下是我第一次进入终端时得到的结果

【问题讨论】：

您使用的是python 2.7，但pandas 1.0.5仅正式支持“Python 3.6.1及以上、3.7和3.8。”。您要么需要升级到像 3.8 这样的新 python（建议在 2.7 完成后），要么安装更旧版本的 pandas，可能是 0.24

【解决方案1】：

转到here 并为您的计算机下载最新的 Python 版本。安装 Homebrew 后，您也可以从终端安装它，如下所示：

$ brew install python

安装最新的 Python 版本后，再次尝试下载 Pandas：

$ pip3 install pandas

如果您想要更完整的安装，您可以下载 Anaconda，因为它会同时安装 numpy、pandas、python 和其他组件。你可以阅读更多关于它的信息here。
