Rails 的 AWS CodeBuild 进程无法安装 pg gem

zcs*_*rei 4 postgresql ruby-on-rails amazon-web-services aws-codepipeline aws-codebuild

我正在尝试使用简单的 3 步 CodePipeline 流程将 Rails 部署到 Elastic Beanstalk。步骤 1 从 GitHub 获取源代码，将其提供给 CodeBuild，然后 CodeBuild 应创建构建并将其传递给 EB。

由于某种原因，当 CodeBuild 进程到达pggem 时，它失败并出现以下错误：

捆绑进程在我的本地计算机上运行没有错误。

我也遇到了与上面相同的问题（除非不使用 CodeBuild）。问题是您正在尝试pg在 version 处安装 gem 1.3.5。截至撰写本文时，Amazon Linux 2 (AL2) 上的 Elastic Beanstalk 默认附带 Postgres 版本 9.2（非常旧）。而pggem 在 9.2 版本之后放弃了对 9.2 的支持1.2.3。看这里。

所以你的两个选择是：

增强 EB 以在构建和部署过程中安装更新版本的 Postgres，例如，如下所述：https: //stackoverflow.com/a/63204453/1852005。
或者您可以通过在 Gemfile 中配置该版本来使用该版本1.2.3的gem。pg该版本于 2020 年 3 月 18 日发布。

这些选项中的任何一个都应该可以帮助您克服该错误。

请注意，您的应用程序还可能连接到 Amazon 的 RDS，该 RDS 具有更新的 Postgres 版本。然而，RDS 位于另一台服务器上，因此不要将两者混淆！eb ssh如果您到服务器并直接在 shell 上运行，您可以看到差异：

[root@ip-XXX-XX-XX-XXX current]# psql --version
psql (PostgreSQL) 9.2.24

与在 Rails 控制台上运行显示 RDS 版本相比：

irb(main):001:0> ActiveRecord::Base.connection.select_value('SELECT version()')
=> "PostgreSQL 11.13 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 7.3.1 20180712 (Red Hat 7.3.1-12), 64-bit"

通过使用 `gem "pg", "= 1.2.3"` 尝试了第二个选项。感谢您的详尽解释！ (3认同)
