【问题描述】：

我的问题与issue deploying rails 5 application to AWS using Elastic Beanstalk due to rb-readline中描述的问题非常相似

但是，通过 AWS 控制台设置 HOME 和/或 HOMEPATH 并没有帮助。我每次都遇到同样的错误。这是相关的日志文件：

当我登录到 EC2 实例时，我可以验证 $HOME 是否按预期设置，但我仍然得到上述结果。我假设我遇到的问题可能是应用程序是在某些 chrooted 配置中启动的，而我选择的目录不存在？或者也许我需要使用带有“：”字符的“路径语法”？

但是在这里反复试验需要很长时间，每次尝试我都会通过仪表板重新下载。所以如果有人有更确定的东西，我真的很感激。

【问题讨论】：

问题似乎不是$HOME 是否设置； /home/webapp 根本不存在

这似乎是合理的。不过，我不知道那是从哪里来的。看起来它正在尝试预编译资产，但我在部署之前就这样做了。我刚刚验证了我正在下载的 zip 文件也有资产。我不确定会发生什么变化。

【参考方案1】：

好吧，我已经解决了这个问题。我从我的构建中消除了 rbreadline gem。这是造成问题的原因。我必须解决另一个问题才能做到这一点，首先我查看了rails console doesn't load due to libreadline

然而给出的解决方案，

ln -s /usr/local/opt/readline/lib/libreadline.dylib \
/usr/local/opt/readline/lib/libreadline.6.dylib 

没用。对我有用的是

ln -s /usr/local/opt/readline/lib/libreadline.dylib \
/usr/local/opt/readline/lib/libreadline.6.2.dylib
