如何获得我的AWS Lambda来访问存储在供应商/捆绑软件中的gem? [英] How can I get my AWS Lambda to access gems stored in vendor/bundle?

问题描述

我正在用Ruby编写Lambda函数，最终将通过Webhook在Slack中向我发送一些通知.所以我的lambda_function文件是

I'm writing a Lambda function in Ruby which will eventually send me some notifications in Slack via Webhook. So what I have for my lambda_function file is

require 'json'
require 'webhook'

def lambda_handler(event:, context:)
    # TODO implement
    { statusCode: 200, body: JSON.generate('Hello from Lambda!') }
    Webhook.post('https://mywebhookurl', {message: 'test'})
end

内联代码编辑器中的目录结构如下:

And the directory structure in my inline code editor looks like this:

Gemfile
Gemfile.lock
lambda_function.rb
vendor/
  bundle/
    ruby
      2.3.0
        gems/webhook

也在2.3.0浴池下，还有其他几个文件夹，包括build_info，cache，doc等.为了将此代码传递到AWS Lambda上，我正在运行

also under the 2.3.0 bath are several other folders including build_info, cache, doc etc. In order to get this code onto AWS Lambda, I'm running

zip -r myLambda.zip *将所有内容打包成zip文件并上传到Lambda.

zip -r myLambda.zip * to get everything into a zip file and uploaded to Lambda.

但是，当我最终去对lambda进行基本测试时，出现以下错误:

However, when I finally go to run a basic test on the lambda, I get the following error:

{
  "errorMessage": "cannot load such file -- webhook",
  "errorType": "Init<LoadError>",
  "stackTrace": [
    "/var/lang/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require'",
    "/var/lang/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require'",
    "/var/task/lambda_function.rb:2:in `<top (required)>'",
    "/var/lang/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require'",
    "/var/lang/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require'"
  ]
}

由于以下教程精确地显示了如何设置我所拥有的东西，但是不起作用.有谁能成功从AWS Lambda的gemfile中提取gem?

There shouldn't be any more to this as the following tutorial shows exactly how to set up what I have, but doesn't work. Does anyone have success pulling gems from their gemfile in AWS Lambda?

推荐答案

在构建带Ruby的AWS Lambda层时遇到了同样的问题.一种快速简便的方法是将所有gem路径添加到AWS Lambda中的Ruby的$ LOAD_PATH中. IE浏览器:

I ran into this same problem when building AWS Lambda Layers w/ Ruby. A quick and easy way to get this to work is to add all of the gem paths to Ruby's $LOAD_PATH in your AWS Lambda. IE:

load_paths = Dir["/opt/ruby/gems/2.5.0/**/lib"]
$LOAD_PATH.unshift(*load_paths)

require 'webhook'

在您的情况下，将"/opt/ruby/gems/2.5.0/**/lib"替换为"./vendor/bundle/ruby/2.3.0/gems/**/lib".

Replace "/opt/ruby/gems/2.5.0/**/lib" with "./vendor/bundle/ruby/2.3.0/gems/**/lib" in your case.

当您执行require 'webhook'时，它将遍历所有路径并遇到"./vendor/bundle/ruby/2.3.0/gems/webhook-1.0.0/lib/webhook.rb"并将其添加到您的AWS Lambda中. require不需要文件扩展名.

When you do require 'webhook' it's going to go and look through all of the paths and come across "./vendor/bundle/ruby/2.3.0/gems/webhook-1.0.0/lib/webhook.rb" and add it into your AWS Lambda. require doesn't require a file extension.

当我们通过捆绑器运行rails时，对我们来说是很多魔术"，包括确保$ LOAD_PATH指向gems.由于AWS Lambda不使用捆绑程序，因此我们需要自己做一些魔术".

When we run rails through bundler it does a bunch of 'magic' for us including making sure that our $LOAD_PATH is pointing at the gems. Since AWS Lambdas don't use bundler, we need to do some of this 'magic' ourselves.
