安装这个需要python环境吗，为什么我一直安装不成功
因为使用了node-addon-api. 而这个库需要使用node-gyp编译C++代码。 node-gyp编译时候需要用python和微软vitual studio编译环境。
所以编译时候用到了python。贴出报错提示信息。

Could not find any Visual Studio installation to use
目前看node-gyp没有找到Visual Studio。电脑需要安装这个。
过段时间我看看能不能把编译好的东西放上去。就不需要你们编译了。

我看gyp那个配置，mac用的xcode是吗

很遗憾，TWAIN官方提供的twain-server还没有提供Mac端。我没在Mac上跑通过。
