解决docker中无法使用编辑器vi 或者 vim

  1. 首先你已经进入容器当中
docker exec -it mysql /bin/bash
  1. 错误场景复现
root@6b0e4fb423e0:~/.halo2/themes/theme-dream/templates/common# vim footer.html
bash: vim: command not found
root@6b0e4fb423e0:~/.halo2/themes/theme-dream/templates/common# vi footer.html
bash: vi: command not found
root@6b0e4fb423e0:~/.halo2/themes/theme-dream/templates/common# yum install vim
bash: yum: command not found
root@6b0e4fb423e0:~/.halo2/themes/theme-dream/templates/common# vi
vigr  vipw
  1. 解决办法
  • 先查看下容器里面的操作系统，如上图错误场景中yum命令没有，可能就是Ubuntu系统
root@6b0e4fb423e0:~/# `more /etc/os-release`
