Lambda 中的新nodejs运行时基于未预安装的 Amazon2 curl。因此curl: command not found在尝试使用它时给出一个。

我如何curl回到新的nodejs 10.x and 12.x运行时？

我找不到curllambda 层。

推荐的方式是使用request客户端nodejs。但是，如果您在curl从 升级node 8.x到时投入过多node 12.x，您将需要自己包含curl二进制文件和所需的库。

我创建了一个 lambda 层arn:aws:lambda:us-east-1:310788757301:layer:curl:15。您可以自由使用它，但是我将其用于个人用途，因此我不建议在生产环境中使用它。相反，我将为您提供有关构建您自己的curllambda 层的指南。

我上传了curl 7.69.1 (x86_64-redhat-linux-gnu)，并用来ldd /opt/bin/curl找出缺少哪些库。包含所有必需的库后，输出如下：

我下载了 RedHat 6 和 Centos 6 库的混合，它似乎工作。这是您将需要的清单。
