Centos 7节点canvas/Fabricjs编译错误

Question

在 AWS Centos 7 机器上，我正在努力安装 Fabricjs 并在 Angular 4 网络应用程序中工作。运行系统库问题超出了我对Centos 7的理解。我该如何解决？

npm install fabric --save

> node-gyp rebuild

对于它的价值，我似乎安装了引用的库，但不能确定：

# yum install libjpeg
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: centos.mirror.constant.com
 * epel: s3-mirror-us-east-1.fedoraproject.org
 * extras: mirror.lug.udel.edu
 * updates: mirror.trouble-free.net
Package libjpeg-turbo-1.2.90-5.el7.x86_64 already installed and latest version
Nothing to do

Answer 1

您需要安装这些库的开发版本。 node-canvas 建议的是：

sudo yum install cairo cairo-devel cairomm-devel libjpeg-turbo-devel pango pango-devel pangomm pangomm-devel giflib-devel

如果您打算在浏览器中 angular 使用 fabricjs，您不需要从 npm 安装它，您仍然可以从 CDN 引用它，这对您来说更容易，并且可能会减少部署时间。
