无法在 aws 层中添加 pandas 并出现错误

Question

我在 lambda 函数中导入 pandas/numpy 时出错：

我添加了 pandas/numpy 作为 aws 层，我也以同样的方式添加了 pymysql，它工作正常。

正在处理 windows 10，
在 lambda 中使用 python3.7 同样
使用 pip install pandas -t
构建 zip 包在目录中 - python\lib\python3.7\site-packages

{

包的压缩应该在构建文件夹中完成，即使您将包安装在 site-packages https://www.youtube.com/watch?v=zrrH9nbSPhQ - 有一些很好的步骤可以遵循。

Pandas 可能是一个巨大的 zip 文件，lambda 层可能不支持。您可能需要检查 pandas- 示例 pandas-xlrd.
