node.js - 在elasticbeanstalk上安装npm canvas - npm安装错误

Question

我正在尝试通过 Elasticbeanstalk 部署在 EC2 上运行的 Node.js 服务器。我遇到的问题是在重建 canvas npm 模块期间。命令“canvas@1.1.6 install: node-gyp重建”失败如下:

> canvas@1.1.6 install /tmp/deployment/application/node_modules/canvas
> node-gyp rebuild

gyp ERR! clean error 
gyp ERR! stack Error: EACCES, unlink 'build'

问题似乎是 npm install canvas 命令没有以适当的权限运行。如果我手动 ssh 进入服务器并运行“sudo npm install canvas”，一切正常。这告诉我所有适当的依赖项都安装良好(我遵循了这些说明: https://github.com/Automattic/node-canvas/wiki/Installation---Amazon-Linux-AMI-(EC2) )。只是 elasticbeanstalk 部署造成了痛苦。

我尝试通过向 .ebextensions 内的 .config 文件添加命令来在部署期间启用 root 访问权限，如下所示:

option_settings:
  - namespace: aws:elasticbeanstalk:container:nodejs:staticfiles
    option_name: /public
    value: /public
  - option_name: NODE_ENV
    value: production

commands:
  01_enable_rootaccess:
    command: echo Defaults:root \!requiretty >> /etc/sudoers
  02_no-cert:
    command: sudo /opt/elasticbeanstalk/node-install/node-v0.10.10-linux-x64/bin/npm config set ca ""

但似乎没有任何区别。

我做错了什么，如何在 eb 部署期间让 canvas 很好地安装？

你有canvas的所有依赖项吗？为了让它为我工作，我必须安装以下内容:cairo、cairo-devel、libjpeg-devel、 giflib-devel、libpng-devel(应该已经安装)。

您可以通过在 .ebextensions 之一中添加以下内容来确保安装所有这些内容:

packages:
    yum:
        cairo: []
        cairo-devel: []
        libjpeg-devel: []
        giflib-devel: []
        libpng-devel: []

我认为 Canvas 可能会尝试安装它没有但没有权限的东西。

尝试一下并让我知道它是如何工作的。
