node-qrcode安裝在heroku上

我有問題在heroku上安裝這個軟件包。有沒有辦法做到這一點？node-qrcode安裝在heroku上

我看到這是一個畫布模塊的問題，但我不知道該怎麼做。

這是在heroku上安裝的日誌。我不知道如何讓更多：

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! Tell the author that this fails on your system: 
     npm ERR!  node-waf configure build 
     npm ERR! You can get their info via:

你可以發佈你的完整版本輸出嗎？ – hunterloftis 2015-04-23 23:08:16

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

但在其自述，它會告訴你使用Heroku的-buildpack的多，這是過時。我所做的就是，在命令行中使用Heroku的列工具：

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

的Heroku buildpacks：添加的Heroku/
的NodeJS

然後推到這樣的Heroku它可以再次構建包。
