UBUNTU，NODE-GYP，CANVAS-获取构建错误

如何解决UBUNTU，NODE-GYP，CANVAS-获取构建错误

你好，我在安装Canvas软件包时遇到问题。

打包版本6.1.13，并尝试了6.1.3

系统：Ubuntu 18.04.5 节点12.18.4 LTS Python 2.7 已安装g ++ 安装了pkg-config 安装了libjpeg

在npm安装canvas或完全安装后，我得到：

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'

还有更多相似之处。

解决方法

将NodeJ降级到v8.16.2将解决此问题，并且node-gyp不再在日志中大喊大叫。
