如何在AWS Lambda Cutom RunTime（Shell）中使用AWS CLI二进制文件

Question

无法在Lambda自定义运行时运行AWS CLI，并出现错误：

  

找不到aws命令

python3 -m venv lambdaVirtualEnv 
source activate lambdaVirtualEnv
pip3 install awscli
copied the aws binary and contents under the site-packages to lambdaLayerDir 
Created a lambda layer using lambdaLayerDir.zip file. 

function handler () 
{
    PATH=${PATH}:${LAMBDA_TASK_ROOT}
    echo $PATH
    EVENT_DATA=$1
    RESPONSE="{\"statusCode\": 200, \"body\": \"Hello from Lambda!\"}"
    echo $RESPONSE
    aws
}

输出：

> * Connection #0 to host 127.0.0.1 left intact
/var/task/hello.sh: line 9: aws: command not found
