Mac安装docker教程安装后zsh: command not found: docker解决办法
我 · 更新于 2022/8/15
1、安装完docker后，这时候⼤多教程都会让我们打开终端，输⼊命令：
docker --version
然后出现正确的docker版本，说明安装成功。
可是实际安装时，因为没有配置环境变量，系统识别不了docker命令，所以会报
docker :command not found
所以我们需要配置环境变量
2、在终端中使⽤命令：
sudo vim /etc/profile
然后按i，进⼊编辑模式，在profile的末尾按回车，新起⼀⾏，添加环境变量：
-

然后按esc退出编辑模式，输⼊:w 回车，然后输⼊:q再回车，保存退出。
3、此刻我们需要使我们配置的环境变量⽴即⽣效，在终端中使⽤命令：
source /etc/profile
4、然后我们再来试⼀试docker命令：
docker --version
Docker version 20.10.16, build aa7e414
FINALLY，终于识别了!
5、docker --version 会给出简单的docker版本信息，如果要知道关于安装的docker更多信息，可以使⽤以下两个命令：
-
