node-qrcode安装在heroku上

我有问题在heroku上安装这个软件包。有没有办法做到这一点？node-qrcode安装在heroku上

我看到这是一个画布模块的问题，但我不知道该怎么做。

这是在heroku上安装的日志。我不知道如何让更多：

npm ERR! [email protected] preinstall: `node-waf configure build` 
     npm ERR! `sh "-c" "node-waf configure build"` failed with 1 
     npm ERR! 
     npm ERR! Failed at the [email protected] preinstall script. 
     npm ERR! This is most likely a problem with the canvas package, 
     npm ERR! not with npm itself.

     npm ERR! You can get their info via:

你可以发布你的完整版本输出吗？ – hunterloftis 2015-04-23 23:08:16

我成功地使用这个Heroku的builpack： https://elements.heroku.com/buildpacks/mojodna/heroku-buildpack-cairo

但在其自述，它会告诉你使用Heroku的-buildpack的多，这是过时。我所做的就是，在命令行中使用Heroku的列工具：

的Heroku buildpacks：设置--index 1 https://github.com/mojodna/heroku-buildpack-cairo.git

的Heroku buildpacks：添加的Heroku/
的NodeJS

然后推到这样的Heroku它可以再次构建包。
