Question

我想官方软件包应该是稳定的而不是抛出编译警告，所以也许我的版本错误了？

规格：
- OSX 10.8.5
- Xcode 5.1.1
- 节点4.2.4
- npm 2.14.12

$ npm install canvas --save-dev

> canvas@1.3.7 install /Users/petruza/Source/Misc/test/electron-quick-start/node_modules/canvas
> node-gyp rebuild

这些警告意味着开发人员只是粗心大意。只要没有任何基金会或公司支持，我就不会将npm上的任何内容视为正式的。只需忽略这些警告。

在OSX上安装节点画布我收到警告，为什么会这样？
