【问题描述】：
所以这是一个令人困惑的问题。我不确定我哪里出错了，但我在某个地方做了，鉴于问题，它似乎应该是一个简单的修复。
第一次，我的 Rails 应用程序每次在终端中启动时都会崩溃。它崩溃是因为它试图连接到“development .rb”——单词的结尾和句号之间有一个空格。每次启动时，它都会创建一个名为“development.log”的文件。
我实际上没有“开发 .rb”文件，所以我不确定它为什么要尝试连接它。
所以在我的代码中的某个地方我必须告诉它只连接到 development.rb（没有空格）。关于如何做到这一点的任何想法？

【问题讨论】：
-
你用什么命令来启动或者你的 Procfile 是什么样的？
-
看起来问题来自 Rails 正在等待适配器的事实，可能在您的数据库文件中，例如例如 mysql 或 mysql2。
-
请发布 config/database.yml
-
您可能有一个
RAILS_ENV环境变量，其末尾有一个空格。在你的配置中寻找类似export RAILS_ENV="development "的东西。也可以在 shell 提示符下尝试确认：echo $RAILS_ENV | od -c;在八进制转储中查找尾随空格。
