Was trying to install this this on a CentOS 6.7 installation and started receiving errors.

Here is the error log.

Hmm, seems like that line was added in #935 and been there since alpha.3 🤔

CentOS has an ancient version of canvas cairo. You could try to get a more recent version, but we can also define that value I think.

edit: typo, s/canvas/cairo.

[Liguo-Wang]

@LinusU yes, you are right. This question has been bothering me for a long time.

[zbjornson]

@wangliguo6666 the version of cairo (I said "canvas" by mistake in my earlier comment) shown in your log is from 2009. I won't have a chance to submit a PR to fix this for a few days. Meanwhile you can install a newer version of cairo, or use canvas-prebuilt (npm install canvas-prebuilt).

@zbjornson ，thank you. I will have a try.😄

[Liguo-Wang]

@LinusU @zbjornson Thanks for your help.😂
I've upgraded the system to centos7, it's working fine now.
It's really a Cairo version of the problem. Now it is 1.14.8.
