我最近将我的系统更新到Ubuntu 18.04 LTS,从那时起,Ruby版本似乎已经更新到2.5.问题在于,在尝试部署使用Capistrano的项目时,它现在会抱怨找不到Ruby 2.3.
它在运行rvm install 2.3时尝试安装的版本是2.3.4,显示的第一个错误是“Error running’__rvm_make -j4’”.我尝试删除RVM并再次安装,但没有解决这个问题.日志是一个巨大的文件,它什么也没告诉我.
然后,我尝试使用rbenv,这也会导致错误：

安装它有什么作用？或者不可能再安装这些旧版本？
我有同样的问题,虽然看起来问题是在gcc中,在我的情况下问题是在libssl-dev中,这是帮助我的：
sudo apt purge libssl-dev && sudo apt install libssl1.0-dev
我用rbenv.如果使用rvm,运行上一个命令后可能遇到问题：
/usr/share/rvm/scripts/base: No such file or directory
我建议尝试rbenv.安装libssl1.0-dev后,一切都完美无瑕.
