VeighNa框架的LevelDB数据库接口
说明
基于plyvel开发的LevelDB数据库接口。
对于不同操作系统需要安装不通版本的plyvel。对于linux与windows会自动安装适配的plyvel与plyvel-win32。
对于macox操作系统，需要手动下载源码进行安装，并在安装前将源码setup.py中
if platform.system() == 'Darwin':
extra_compile_args += ['-stdlib=libc++']
修改为
if platform.system() == 'Darwin':
extra_compile_args = ['-Wall', '-g', '-x', 'c++', '-std=c++11', '-fno-rtti']
再运行
python -m pip install .
进行手动安装。方法参考自[https://github.com/wbolster/plyvel/issues/114]。
