Z3 v4.3.2 example.py Mac OS X 10.10 上的执行错误

Question

我正在尝试在 Mac OS X 10.10.2.

上构建 Z3 最新版本 (v4.3.2)

正在从 http://download-codeplex.sec.s-msft.com/Download/SourceControlFileDownload.ashx?he ProjectName=z3&changeSetId=cee7dd39444c9060186df79c2a2c7f8845de415b to follow the command in http://z3.codeplex.com/SourceControl/latest#README 下载最新源。

CXX=clang++ CC=clang python scripts/mk_make.py
cd build
make
sudo make install

构建和安装似乎没问题，但是，当我尝试运行 example.py 时，出现了这个错误。

Traceback (most recent call last):
  File "example.py", line 3, in <module>
    x = Real('x')
  File "/Library/Python/2.7/site-packages/z3.py", line 2774, in Real
    ctx = _get_ctx(ctx)
  File "/Library/Python/2.7/site-packages/z3.py", line 210, in _get_ctx
    return main_ctx()
  File "/Library/Python/2.7/site-packages/z3.py", line 205, in main_ctx
    _main_ctx = Context()
  File "/Library/Python/2.7/site-packages/z3.py", line 151, in __init__
    conf = Z3_mk_config()
  File "/Library/Python/2.7/site-packages/z3core.py", line 1036, in Z3_mk_config
    r = lib().Z3_mk_config()
  File "/Library/Python/2.7/site-packages/z3core.py", line 24, in lib
    raise Z3Exception("init(Z3_LIBRARY_PATH) must be invoked before using Z3-python")
z3types.Z3Exception: init(Z3_LIBRARY_PATH) must be invoked before using Z3-python
Exception AttributeError: "Context instance has no attribute 'lib'" in <bound method Context.__del__ of <z3.Context instance at 0x227800>> ignored

我在环境变量中添加了 export Z3_LIBRARY_PATH=/Library/Python/2.7/site-packages/，并尝试了 64 位 python 和 arch -x86_64 python example.py 以获得相同的结果。

从 Using Z3Py With Python 3.3，我试图将 libz3.a/dylib/java.dylib 文件复制到 /Library/Python/2.7/site-packages，但没有成功。

可能出了什么问题？

与MacOS支持的64位python有关。根据提示，我用 brew 安装了 python，现在可以正常工作了。
