Installation on Heroku needs updating

[chico]

I followed https://github.com/Automattic/node-canvas/wiki/Installation-on-Heroku but it's now out of date. Heroku now supports multiple buildpacks out of the box.

The simplest way to get node-canvas working is to add the cairo buildpack using the following heroku command:

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

Thanks you @chico

note that this workaround hasn't been updated for heroku-16 stack, you need to have cedar-14 stack

See the end of this thread if you have old Heroku CLI it may throw an error when setting cedar-14 stack

I just tested this with version 2.0.0-alpha.12, and got it working with this buildpack: https://github.com/rista404/heroku-buildpack-cairo

Just add it before nodejs buildpack and it should be working.

@rista404 I was able to get node-canvas running on Heroku without any issues (see: #843 (comment))
Although it looks like you are using cedar-14 stack, while I'm using heroku-16 - maybe that's the difference

In addition to the other solutions commented above... I just successfully installed canvas 2.0.0-alpha.12 and 1.6.11 on the vanilla heroku-16 stack. Both just worked thanks to prebuilds. If anyone has a need to make a from-source build work, I can look into it.
