Question

我在heroku上安装此软件包时遇到问题。有办法吗？

我看到这是canvas模块的问题，但我不知道该怎么做。

这是heroku上的安装日志。我不知道如何获得更多：

npm ERR! canvas@0.12.1 preinstall: `node-waf configure build`
       npm ERR! `sh "-c" "node-waf configure build"` failed with 1
       npm ERR! 
       npm ERR! Failed at the canvas@0.12.1 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:
       npm ERR!     npm owner ls canvas
       npm ERR! There is likely additional logging output above.

我成功使用了这个Heroku构建包： https://elements.heroku.com/buildpacks/mojodna/heroku-buildpack-cairo

但在其README中，它告诉您使用 heroku-buildpack-multi ，这已被弃用。我做的是，在命令行中使用Heroku Toolbelt：

heroku buildpacks：set --index 1 https://github.com/mojodna/heroku-buildpack-cairo.git

heroku buildpacks：添加heroku / nodejs

然后推送到Heroku，这样它就可以再次构建包。

在heroku上安装node-qrcode
