&引用；无法加载本机模块'；加密。密码。_raw_ecb'；：尝试'_raw_ecb.cpython-38-x86_64-linux-gnu.so'；在python 3.8上运行Lambda时

我正在尝试用python进行加密和描述，并尝试在lambda上运行它

我得到以下错误：

{
  "errorMessage": "Cannot load native module 'Crypto.Cipher._raw_ecb': Trying '_raw_ecb.cpython-38-x86_64-linux-gnu.so': /var/task/Crypto/Util/../Cipher/_raw_ecb.cpython-38-x86_64-linux-gnu.so: cannot open shared object file: No such file or directory, Trying '_raw_ecb.abi3.so': /var/task/Crypto/Util/../Cipher/_raw_ecb.abi3.so: cannot open shared object file: No such file or directory, Trying '_raw_ecb.so': /var/task/Crypto/Util/../Cipher/_raw_ecb.so: cannot open shared object file: No such file or directory",

  ]
}

我确信问题出在“pycryptodome-3.10.1.dist info”库上，因为它与lambda OS不兼容，因为该代码在我的本地系统上运行良好，该系统也在python 3.8上

有谁能帮我解决这个问题吗？

根据我的经验，包含lambda函数依赖项的最可靠的方法是通过使用docker，如中所述

因此，您可以将

pycrypto

添加到函数中，如下所示：

创建空文件夹，例如

mylayer

转到文件夹并创建包含以下内容的

requirements.txt

文件：

运行以下docker命令：

该命令将为python3.8创建图层：

docker run -v "$PWD":/var/task "lambci/lambda:build-python3.8" /bin/sh -c "pip install -r requirements.txt -t python/lib/python3.8/site-packages/; exit"

将图层存档为zip:

基于AWS控制台中的

mylayer.zip

创建lambda层。别忘了将

兼容运行时

指定到

python3.8

将步骤5中创建的层添加到函数中

我用你的代码测试了这个层

它正常工作：

您是如何将该库添加到lambda的？@Marcin通过“pip install-t”在我的本地下载并压缩它，然后上载lambda代码如何在从层调用包时锁定lambda代码？@sumanthshetty您的lambda代码没有区别。您安装了“pycrypto”吗？我有windows本地计算机。需求的内容是什么。txt@sumanthshetty

requirements.txt

中的

pycrypto

。我使用linux创建了这个层。如果windows有问题，可以尝试设置ec2 linux实例。如何将库从ec2计算机移动到本地计算机

docker run -v "$PWD":/var/task "lambci/lambda:build-python3.8" /bin/sh -c "pip install -r requirements.txt -t python/lib/python3.8/site-packages/; exit"

zip -9 -r mylayer.zip python
