在使用docker时，有时候我们需要编辑配置文件，需要使用vim或者vi命令，发现：
root@64801a03b121:/etc/nginx/conf.d# vi default.conf bash: vi: command not foundroot@64801a03b121:/etc/nginx/conf.d# vim default.conf bash: vim: command not found
这是因为vim没有安装，使用如下命令安装：
root@64801a03b121:/etc/nginx/conf.d# apt-get install vimReading package lists... DoneBuilding dependency tree Reading state information... DoneE: Unable to locate package vim
此时需要更新：
root@64801a03b121:/etc/nginx/conf.d# apt-get updateGet:1 http://security-/debian-security buster/updates InRelease [39.1 kB] Get:2 http://cdn-fastly./debian buster InRelease [122 kB] Get:4 http://security-/debian-security buster/updates/main amd64 Packages [112 kB]Get:3 http://cdn-fastly./debian buster-updates InRelease [49.3 kB]Get:5 http://cdn-fastly./debian buster/main amd64 Packages [7899 kB]Get:6 http://cdn-fastly./debian buster-updates/main amd64 Packages [5792 B] Fetched 8226 kB in 5min 26s (25.2 kB/s) Reading package lists...

再次安装：
