本人的Mac版本是10.13.6
官网提供了在MacOS上安装的方法：pip install angr
我试了不行，折腾了好久，找了个折中的方法，使用docker来搭建angr环境
docker search angr
NAME DEscriptION STARS OFFICIAL AUTOMATED angr/angr The next-generation binary analysis platform… 18
docker pull angr/angr
docker run -it angr/angr
这样就行了，要执行脚本的话，将脚本从宿主机拷贝到容器
宿主机向容器中拷贝: docker cp 本地文件路径 `ConTAINER ID`:容器文件路径 容器向宿主机中拷贝: docker cp `ConTAINER ID`:容器文件路径 本地文件路径
但是这样拷来拷去，真心蛋疼
幸好Pycharm可以加载docker中的Python解释器
点击ok等待完成解释器初始化
这样就能在Pycharm中运行脚本了，每次运行会打开一个新容器，程序结束后，这个容器就会关闭
然后就是，可能需要在安装新的模块，这个的话，就需要在容器中安装了，然后将容器打包成一个新的image，最后在Pychram中重新添加新镜像的解释器，总的来说有点麻烦
将容器打包成镜像
docker commit -a 'wangzhou' -m '安装barf模块' 477b9df2d308 angr/angr:v1.0
但如果就仅仅是这样，我就不写这篇博客了，下面讲一下如何在Mac上安装angr和z3-solver
在使用 pip install angr 时，会出现如下报错：
.....

make[2]: *** [src/ast/CMakeFiles/ast.dir/arith_decl_plugin.cpp.o] Error 1

note: This error originates from a subprocess, and is likely not a problem with pip.

这个z3-solver安装失败了，GitHub上搜索说是gcc和clang版本太低，不支持C++17
gcc安装，下载压缩包，https://sourceforge.net/projects/hpc/files/hpc/gcc/gcc-11.2-bin.tar.gz/download
clang安装，sudo port install clang-12
z3-solver通过源码安装：
git clone https://github.com/Z3Prover/z3.git
python scripts/mk_make.py --prefix=/Users/wangzhou/anaconda/ --python --pypkgdir=/Users/wangzhou/anaconda/lib/python3.7/site-packages
cd build/ && make
漫长的编译输出…

cp libz3.dylib python
Z3 was successfully built.
Z3Py scripts can already be executed in the 'build/python' directory.
Z3Py scripts stored in arbitrary directories can be executed if the 'build/python' directory is added to the PYTHonPATH environment variable and the 'build' directory is added to the DYLD_LIBRARY_PATH environment variable.
Use the following command to install Z3 at prefix /Users/wangzhou/anaconda/.
sudo make install
编译成功，执行 sudo make install 完成安装
测试代码：
from z3 import *
x, y, z = Ints('x y z')
s = Solver()
s.add(2 * x + 3 * y + z == 6)
s.add(x - y + 2 * z == -1)
s.add(x + 2 * y - z == 5)
print(s.check())
print(s.model())
x = Int('x')
s = Solver()
a = 65537
b = 64834
c = 41958
s.add(x > 0)
s.add(x % a == b)
s.add(x % b == c)
print(s.check())
print(s.model())
print(z3.get_version())
如果输出正常，那么z3-solver就意味着安装成功了
但是pip freeze的输出没有z3-solver，虽然安装了z3-solver模块，但再次pip install angr时，这个傻叉pip还是要安装z3-solver
分析了下pip freeze的源码，没找到是怎么记录pip安装包的，我感觉可能是每次的安装模块记录存在了某个文件里，想直接去修改下，把这个z3-solver添加进去
好在pip install有个选项是忽略安装依赖的:
pip install xxx --no-deps
上面在安装angr时，最后输出了：
Installing collected packages: z3-solver, unicorn, pysmt, itanium-demangler, protobuf, nampa, gitdb, CppHeaderParser, claripy, ailment, pyvex, GitPython, cle, angr
第一个就是z3-solver，先不管，安装其他的包：
pip install unicorn
pip install pysmt
pip install itanium-demangler
pip install protobuf
pip install nampa
pip install gitdb
pip install CppHeaderParser
这里安装claripy时，也要安装z3-solver，跳过，继续安装其他包：
pip install claripy
Installing collected packages: z3-solver, pysmt, claripy
Running setup.py install for z3-solver
pip install ailment
pip install pyvex
pip install GitPython
pip install cle
最后单独安装claripy和angr这两个包
pip install claripy --no-deps
pip install angr --no-deps
ok，完事
