python - 如何 cx 卡住 Boto3

Question

我创建了这个简单的 python 程序，它向 SQS 发送消息然后检索它。它使用 python 2.7.11 工作。

import boto3 
sqs = boto3.client('sqs')
queue = sqs.get_queue_by_name(QueueName='some-que-name')
queue.send_message(MessageBody='{"phrase": "It\'s the end of the world    as we know it" }' )
for message in queue.receive_messages():
    print message.body

然后我用这个脚本 cxFreeze 它:

from cx_Freeze import setup, Executable

include_mods = []

excludes = ['tkinter', 'cltk']

buildOptions = dict(packages=[], excludes=excludes, includes=include_mods)


executables = [
     Executable('./frozen_boto_3_test.py', 'Console')
]

setup(name='Boto3FrozenTest',
  version='1',
  description='A test to make sure boto3 is working well when frozen',
  options=dict(build_exe=buildOptions),
  executables=executables)

然后当我尝试运行卡住的代码时出现此错误

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/site-packages/cx_Freeze/initscripts/Console.py", line 27, in <module>
    exec(code, m.__dict__)
  File "./frozen_boto_3_test.py", line 1, in <module>
    import boto3

    import botocore.session

    import botocore.configloader
  File "/usr/local/lib/python2.7/site-packages/botocore/configloader.py", line 18, in <module>
    from six.moves import configparser
  File "/usr/local/lib/python2.7/site-packages/six.py", line 203, in load_module
    mod = mod._resolve()
  File "/usr/local/lib/python2.7/site-packages/six.py", line 115, in _resolve
    return _import_module(self.mod)
  File "/usr/local/lib/python2.7/site-packages/six.py", line 82, in _import_module
    __import__(name)
ImportError: No module named ConfigParser

除了这个问题，库似乎动态加载不是 s3、dynamo 或其他服务的服务。

是否有卡住 boto3 的方法？

Answer 1

错误表明正在进行隐藏(动态)导入。如果您在告诉 cx_Freeze 要包含的模块列表中包含它正在寻找的模块 (ConfigParser)，它应该可以工作。您可能需要多次执行此操作。

executables = [cx_Freeze.Executable("MyScript.py")]
includes = ["ConfigParser"]
buildOptions = dict(includes = includes)
cx_Freeze.setup(name, description, options = dict(build_exe = buildOptions),
        executables = executables)

一旦你有了一个工作程序，你也可以这样做而不是操纵你的特定 setup.py。您可以在 cx_Freeze.hooks 模块中添加一个条目，看起来像这样:

def load_boto3(finder, module):
    finder.IncludeModule("ConfigParser")

包括您在此过程中发现的任何其他内容。然后在此处创建拉取请求或问题:
