无法加载此类文件-mysql2

时间：2019-01-14 21:41:55

标签： aws-sam

sam build对我来说运作良好，但当我包括mysql2 gem时，碰巧可以编译它。当我包含这个gem时，lambda告诉我找不到mysql2。

在我的.aws-sam/build/MyLambdaFunctionName/vendor/bundle/ruby/2.5.0/gems中，我有一个mysql2-.0.5.2目录

我也尝试在本地bundle install --path vendor/bundle并上传，但这有所作为

要在我的AWS Ruby Lambda函数中包含mysql2怎么办？

编辑：将--use-container添加到sam build会导致以下情况：

尝试过python 3.6，结果相似：

再远一点。泊坞窗未运行时会发生此错误。当它运行时，我仍然出现错误

我将此失败作为错误添加到了aws-sam-cli的github页面：https://github.com/awslabs/aws-sam-cli/issues/939

MySQL gem使用C库。您的本地环境可能与Lambda的环境不匹配，因此编译后的C库不兼容。尝试在Docker容器中构建它。使用SAM，您可以执行import json file=open('csv.txt','r') lines=[line.strip() for line in file.readlines()] jsonlist=[] for item in lines: club,country,city=item.split(',') data={ 'club':club, 'country':country, 'city':city } jsonlist.append(data) jsonfile=open('jsontxt','w') json.dump(jsonlist,jsonfile) file.close() jsonfile.close() 以在类似Lambda的环境中运行构建。
