在 Python Lambda 包中包含 Java

问题描述

我在 AWS 中有一个 Python lambda 作为依赖项 tabulas，它需要 Java 8+。 有什么办法可以在我的包中包含 Java？我正在使用无服务器框架来打包我的函数和依赖项。

函数返回的错误：

{
  "errorMessage": "`java` command is not found from this Python process.Please ensure Java is installed and PATH is set for `java`","errorType": "JavaNotFoundError","stackTrace": [
    "  File \"/var/task/handler.py\",line 18,in parse\n    data = get_data(tmp_file_path)\n","  File \"/var/task/handler.py\",line 31,in get_data\n    convert_into(file_path,file,output_format='csv',pages='all')\n","  File \"/var/task/tabula/io.py\",line 562,in convert_into\n    _run(java_options,kwargs,path)\n",line 91,in _run\n    raise JavaNotFoundError(JAVA_NOT_FOUND_ERROR)\n"
  ]
}
