Question

我正在尝试在AWS lambda函数中调用python脚本。我为python创建了一个虚拟环境，并安装了需要的pandas，pymongo等模块。这是我的invokepython.js：

var exec = require('child_process').exec;
exports.handler = function(event, context) {
    console.log('Received event:', JSON.stringify(event, null, 2));
    exec("env/bin/python kinesisconsumer.py '"+ JSON.stringify(event) +"'", function(error, stdout) {
    console.log('Python returned: ' + stdout + '.');
    context.done(error, stdout);
});
};

我已安装virtualenv并使用它创建了一个env。使用env/bin/pip install pandas我已经安装了pandas。我已经将env文件夹和我的脚本压缩在一起并将其部署到AWS lambda但是收到错误。

{
  "errorMessage": "Command failed: Traceback (most recent call last):\n  File \"kinesisconsumer.py\", line 4, in <module>\n    import pandas as pd\n  File \"/var/task/env/local/lib/python2.7/site-packages/pandas/__init__.py\", line 13, in <module>\n    \"extensions first.\".format(module))\nImportError: C extension: libcrypto.so.1.0.0: cannot open shared object file: No such file or directory not built.

    "    \"extensions first.\".format(module))",
    "ImportError: C extension: libcrypto.so.1.0.0: cannot open shared object file: No such file or directory not built. If you want to import pandas from the source directory, you may need to run 'python setup.py build_ext --inplace' to build the C extensions first.",
    "",
    "ChildProcess.exithandler (child_process.js:658:15)",
    "ChildProcess.emit (events.js:98:17)",
    "maybeClose (child_process.js:766:16)",
    "Process.ChildProcess._handle.onexit (child_process.js:833:5)"
  ]

我需要在AWS lambda上使用pandas。我应该如何解决这个问题。任何帮助表示赞赏!!!

我在Amazon Linux上做的就像我在ubuntu机器上做的那样。它的工作。解释here

为了在AWS Lambda中工作，需要为Amazon Linux x86_64编译扩展模块＆＃34;
