Question

我正在研究rails5项目。我不小心输入了brew upgrade（我应该先卸载imagemagick然后再安装）

bin/rails c命令现在不起作用。

环境：

Mac os 10.12
红宝石2.5.1p57（2018-03-29修订版63029） [x86_64-darwin16]
使用gem'mysql2'，'0.4.10'滚动5.1.6.1

我尝试过：

brew link readline --force
ln -s /usr/local/opt/readline/lib/libreadline.7.0.dylib /usr/local/opt/readline/lib/libreadline.6.dylib
brew info readline
readline：稳定的8.0.0（瓶装）[仅可放入水壶] 用于命令行编辑的库 /usr/local/Cellar/readline/8.0.0（49个文件，1.5MB）* 从瓶子倒在2019-02-15 17:16:19

但两者仍然没有任何变化，选中mysql.server start并得到Starting MySQL.......... SUCCESS!

还检查了mysql --version，得到了mysql Ver 8.0.15 for osx10.12 on x86_64 (Homebrew)

bin/rails s
Sorry, you can't use byebug without Readline. To solve this, you need 
to rebuild Ruby with Readline support. If using Ubuntu, try `sudo apt-get
install libreadline-dev` and then reinstall your Ruby.
