Have you followed the installation instructions?

Following the "Install with Chocolatey" instructions for windows led me to this problem.
Following the "Install Manually" instructions fixed the problem. (downloading GTK 2 and placing it in C:\GTK)

The choco install seemed to be lacking the sources.

unzipping GTK to C:\GTK worked, it is missing from the automatic instructions you still have to download GTK separately.

I can confirm that using manual install solve this issue.
Does anyone from contributors/owner of this repo would like me to create PR to update wiki ?

Yes please ☺️

@eko24ive anyone can edit the wiki without a PR, so if you find a way to improve it, go ahead. That's how the Chocolatey instructions ended up there. There have been a few issues with those instructions, so we might want to just remove them if they can't be made more reliable.

[eko24ive]

Well, for myself I'd removed the Chocolatey guide, but I don't want to do so until we see solid proof that Chocolatey instructions aren't working for the reasonable amount of people.

@zbjornson @LinusU
I've updated the wiki. It was my first time with wikis, so I was expected PR-like procedure or something 😂
I decided to add a warning for Chocolatey instruction for now, since we don't know if it doesn't work for people at all. Also, I've added an anchor link to "Install Manually" section in the warning message.Please review it and let me know if something not right.

[zbjornson]

Thanks @eko24ive. If I have time I'll see if I can come up with a better version of the Chocolatey instructions sometime.

[eko24ive]

@zbjornson no problem.

Also, I saw "Installation on Heroku" article on the wiki, and I was wondering why it is even there.
You see, I have my dyno on Heroku running at heroku-16 stack, and in my project I'm using chartjs-node which is depended on node-canvas and I was able to get it up and running right out of the box without using any buildpacks.
Probably that wiki article must be revised as well, what do you think ?

[zbjornson]

@eko24ive the Heroku info was also submitted by someone else in response to one of these issues: https://github.com/Automattic/node-canvas/search?q=heroku&type=Issues. I don't know anything about Heroku to give feedback there, sorry.

[eko24ive]

I'm just saying that I was sort of able to get node-canvas up and running without using any custom buildpacks - right out of the box. Do you have anyone on the collaborators team to check it by chance?

[chearon]

I don't think any of the collaborators use Heroku but if you're sure it worked with zero config, I say go ahead and remove the wiki or add a note saying your setup didn't need any changes.

[eko24ive]

Ok, I'll double check it then and if it's so - I'll add a note to the article.

@zbjornson @eko24ive maybe python2 can be switched to python and microsoft-build-tools switched to visualstudio2017-workload-vctools? These build tools have been working for a lot of Windows developers:

visualstudio2017-workload-vctools is the same as microsoft-build-tools but just more up to date:

Why is GTK needed? Ah, I see, because of Cairo. Can it be installed using Chocolatey too? Eg. the GTK Runtime package?

@Josehower and I will try these changes to the Chocolatey instructions with some bootcamp students: https://github.com/upleveled/next-starter-peacock#getting-started
