二、解决

安装运行 fava 时一个错误 dlsym(RTLD_DEFAULT, magic_open):

一、报错:

    File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/ctypes/__init__.py", line 366, in __getitem__
    func = self._FuncPtr((name_or_ordinal, self))  
    AttributeError: dlsym(RTLD_DEFAULT, magic_open): symbol not found  
    

二、解决

查找资料, 有的介绍是 Macos dlsym 此等环境 xcode 的问题, 需要安装新的 xcode 之类的解决方案, 成本太高  

后发现该问题应为 Python-magic 库相关, 尝试升级解决:

   pip3 install --upgrade python_magic

如上由 pip3 install --upgrade python_magic 由 0.4.15 升级到 0.4.18 该问题被修复.
