Rails控制台无法在开发中启动。 Rails服务器会启动，但不会启动。运行Ruby 2.5.1，Rails 5.2.2.1
在此站点上尝试了许多类似的错误，因为服务器没有启动，但找不到控制台的类似错误。尝试注释掉这两个春季宝石。不用找了。尝试注释掉bootsnap gem，但这也不起作用。
错误

尝试清洁引导缓存（rm -rf tmp/cache/bootsnap-*），如果这样做没有帮助-请重新安装ruby

此错误消息
Library not loaded: /usr/local/opt/readline/lib/libreadline.7.dylib
告诉您Ruby不再找到该版本所针对的Readline版本：
原因可能是您最近运行了brew upgrade并在计算机上将readline更新为版本8，但是Ruby仍期望版本7。
您有两个选择：
要添加该符号链接，请打开您的终端并运行：
ln -s /usr/local/opt/readline/lib/libreadline.8.0.dylib /usr/local/opt/readline/lib/libreadline.7.dylib
