Question

我使用python setup.py bdist_egg命令构建了pyahocorasick库，并将其上传到Spark以进行PySpark作业。

但是，出于安全原因，不能通过Spark群集上的pkg_resources.resource_filename()方法导入pyahocorasick中的.so文件。

Traceback (most recent call last):
  File "spark_datawash.py", line 251, in <module>
    import ahocorasick

pkg_resources.ExtractionError: Can't extract file(s) to egg cache

The following error occurred while trying to extract file(s) to the Python egg
cache:

  [Errno 13] Permission denied: '/home/.python-eggs'

The Python egg cache directory is currently set to:

  /home/.python-eggs

Perhaps your account does not have write access to this directory?  You can
change the cache directory by setting the PYTHON_EGG_CACHE environment
variable to point to an accessible directory.

这是pyahocorasick导入.so：

的方式

def __bootstrap__():
    global __bootstrap__, __loader__, __file__
    import sys, pkg_resources, imp 
    __file__ = pkg_resources.resource_filename(__name__, 'ahocorasick.so')
    __loader__ = None; del __bootstrap__, __loader__
    imp.load_dynamic(__name__,__file__)
__bootstrap__()

我可以通过resource_stream()而不是resource_filename()或其他方式导入.so，而无需从绝对文件路径中读取吗？谢谢大家。

顺便说一句，由于其他原因，我无法在Spark群集的每个节点上安装pyahocorasick。因此，我必须上传一个鸡蛋拉链分发以供日后使用。
