【问题描述】：

我是红宝石的新手。我正在部署一个 ruby 应用程序，它从 slack 中读取错误 id，向 jira 发送请求，并将响应发送到 slack 并返回错误详细信息。将此应用程序部署到 Cloud Foundry 时遇到问题。我在用， Cloud Foundry 构建包版本：1.8.25 捆绑器 2.1.4 红宝石 2.7.0 红宝石 3.1.4.

我有一个 proc 文件，其中包含命令 bundle exec rackup config.ru -p $PORT，当我执行 cf push 时，我收到以下错误：

如果您需要任何其他信息，请告诉我。

在运行“捆绑安装”尝试安装 gems 时，出现此故障。

【问题讨论】：

你用的是什么栈？ cf stacks 的输出是什么。如果将 -s cflinuxfs3 添加到 cf push 命令或将 stack: cflinuxfs3 添加到 manifest.yml 会发生什么？
当我做cf stacks时，我可以看到cflinuxfs2 & cflinuxfs3。
Hai @DanielMikusa，Container 现在已启动，但 ruby 应用程序未启动。我要关闭这个。谢谢。

【解决方案1】：

从提供的信息中并不完全清楚，但是这个错误：

2020-10-06T23:07:22.40-0400 [STG/0] ERR /tmp/rubygems270167546/lib/rubygems/core_ext/kernel_require.rb:92:in require': /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1: version OPENSSL_1_1_1' 未找到（/tmp 需要/contents329128731/deps/0/ruby/lib/ruby/2.7.0/x86_64-linux/openssl.so) - /tmp/contents329128731/deps/0/ruby/lib/ruby/2.7.0/x86_64-linux/openssl .so（加载错误）

看起来您有一个需要在 cflinuxfs2 上使用 cflinuxfs3 的 buildpack。这两个堆栈有不同的 OpenSSL 版本，cflinuxfs3 有 1.1.1。

切换堆栈至少应该允许您跳过此错误。

cf push -s cflinuxfs3 或在 manifest.yml 中设置 stack: cflinuxfs3。

对于它的价值，在我写这篇文章的时候，cflinuxfs2 已经很老了，而且不支持了。如果您使用的平台仍默认使用 cflinuxfs2 堆栈，甚至将其作为选项提供，您应该与您的平台运营团队讨论尽快升级。
