Question

libarchive的release notes表示由于旧版本的libarchive包含在MacOS中，因此建议将LD_LIBRARY_PATH更改为指向最近的libarchive副本的位置。

我已经使用此代码尝试实现该功能，但在运行脚本时收到错误消息。

import os

print os.environ.get('LD_LIBRARY_PATH') #Check what the current path is 

os.environ['LD_LIBRARY_PATH'] = '/Library/Python/2.7/site-packages/'
print os.environ.get('LD_LIBRARY_PATH') #Check the variable has been set 

import libarchive.public

错误：

None
/Library/Python/2.7/site-packages/
Traceback (most recent call last):

func = self._FuncPtr((name_or_ordinal, self))
AttributeError: dlsym(0x7fb08b741000, archive_read_support_filter_all): symbol not found

我无法在那里找到一个很好的答案。

从工具文档中不清楚，但是基于一个线程：https://github.com/dsoprea/PyEasyArchive/issues/16我将另一个环境变量设置到可以找到底层c库的地方。在我的情况下，它被自制软件放在我的Mac上。

os.environ['LA_LIBRARY_FILEPATH']='/usr/local/opt/libarchive/lib/libarchive.dylib'

import libarchive.public

为我工作。

如何正确导入最新的libarchive以便在Mac OS上使用
