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没有帮助。我每次都会得到同样的错误。这是相关的日志文件：

当我登录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。我假设可能我遇到的问题是应用程序是在一些chrooted配置中启动的，而我选择的目录不存在？或者我可能需要使用带有“：”字符的“路径语法”？
但是反复试验需要花费很长时间才能完成，我每次尝试都会通过仪表板进行重新下载。所以，如果某人有更明确的东西，我真的很感激。
答案 0 :(得分：0)
好吧，我已经解决了这个问题。我从我的版本中删除了rbreadline gem。这导致了这个问题。我必须解决另一个问题，首先我查看了rails console doesn't load due to libreadline
然而，给出了解决方案，
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
