Elasticbeanstalk 如何在我的配置文件中指定 Pango >= 1.38？

我收到以下错误：

Elasticbeanstalk 用户警告：@font-face 支持需要 Pango >= 1.38

我需要在 elasticbeanstalk 上安装 Pango >= 1.38。

我有以下.ebextensions\01_packages.config文件

packages:
  yum:
    git: []
    postgresql93-devel: []
    libxslt-devel: []
    libxml2-devel: []
    python36: []
    gcc-c++: []
    gcc-gfortran: []
    atlas-sse3-devel: []
    lapack-devel: []
    libffi: []
    libffi-devel: []
    cairo-devel: []
    pango: []
    pango-devel : []

这是根据 eb-activity.log 中的此摘录加载 pango 1.28

我试过修改为

...
    pango: 1.44.0
    pango-devel : 1.44.0 

安装时出现以下错误：

命令在实例上失败。返回码：1 输出：Yum 没有可安装的 pango-1.44.0。

我是否安装了更新版本的 Pango？
