Node.js node pre gyp--安装canvas模块时返回生成错误

在将我的项目部署到ElasticBeanStalk时，我遇到了一些问题。在安装canvas 2.7.0模块时，存在节点预gyp--返回到构建错误

我不确定这是否是权限错误，原因如下

 Error: EACCES: permission denied, mkdir '/var/app/staging/node_modules/@tensorflow/tfjs-node/deps'

这里是我在eb-engine.log中的错误

我知道这是权限错误，当服务器端npm安装命令运行时，ec2实例没有创建任何文件夹的权限，因此我找到了两个解决方案，第一个是create.npmrc file并将unsafe perm设置为true，另一个是create.ebextension file并设置根权限
