UBUNTU、NODE-GYP、CANVAS-得到构建错误

Question

Hello I have problem with installation Canvas package.

Package Version 6.1.13 and tried 6.1.3

System: Ubuntu 18.04.5 Node 12.18.4 LTS Python 2.7 g++ installed pkg-config installed libjpeg installed

After npm install canvas or pure install I get:

canvas@1.6.13 install /home/grzegorz/www/ouch/BodySpaces.Portal/node_modules/fabric/node_modules/canvas
> node-gyp rebuild

make: Entering directory '/home/grzegorz/www/ouch/BodySpaces.Portal/node_modules/fabric/node_modules/canvas/build'

将 NodeJs 降级到 v8.16.2 将解决这个问题，并且 node-gyp 不再在日志中大喊大叫。
