如何冻结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

然后我用下面的脚本来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，当我试图运行冻结的代码时，我会得到这个错误。

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__)

    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，库似乎动态地加载不是s3、dynamo或其他服务的服务。

有冷冻boto3的秘方吗？

Answer 1

错误显示正在发生隐藏(动态)导入。如果您将它正在寻找的模块(ConfigParser)包含在您告诉cx_Freeze包含的模块列表中，那么它应该可以工作。你可能得这样做好几次。

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

一旦您有了一个工作程序，您也可以这样做，而不是操纵您的特定setup.py。您可以在cx_Freeze.hooks模块中添加一个条目，如下所示：

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

包括你沿途发现的任何其他东西。然后在这里创建一个拉请求或问题：

freeze

谢谢安东尼·图宁加

我在这里还发布了几个步骤：

添加"ConfigParser“和"HTMLParser”，正如安东尼所指出的

from cx_Freeze import setup, Executable

include_mods = ["ConfigParser", "HTMLParser"]

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)

导出AWS_DATA_PATH=/usr/local/lib/python2.7/dist-packages/botocore/data从：requests.exceptions.SSLError: [Errno 2] No such file or directory

导出REQUESTS_CA_BUNDLE=/usr/local/lib/python2.7/dist-packages/botocore/vendored/requests/cacert.pem

使用较低级别的代码使用sqs：

import boto3 

sqs = boto3.client('sqs')

queue = sqs.create_queue( QueueName="my-queue" )
sqs.send_message(QueueUrl=queue["QueueUrl"] , MessageBody='{"phrase": "It\'s the end of the world as we know it" }' )
message = sqs.receive_message(QueueUrl=queue["QueueUrl"])
for msg in message['Messages']: 
    print m

sg‘’Body‘

在此之后，sqs适用于OP上发布的“hello world”脚本。
