在ubuntu下安装git时遇到的问题记录_apt-get install git: command not found

 问题：

用root账号登录时，使用 apt-get install git命令安装git时，报错如下

Command 'apt-get' is available in '/usr/bin/apt-get'
The command could not be located because '/usr/bin' is not included in the PATH environment variable.
apt-get: command not found

切换到普通管理员账号登录，使用sudo apt-get install git安装git安装成功

再切换到root，git --version查看git版本，仍然报错

root@alibaba:~# git --version
Command 'git' is available in '/usr/bin/git'
The command could not be located because '/usr/bin' is not included in the PATH environment variable.
git: command not found

查找得报错原因为apt-get不在/usr/bin下

解决方法：

使用root账号登录

输入以下代码：

root@alibaba:~# cd /bin/
root@alibaba:/bin# PATH="$PATH:/usr/bin"
root@alibaba:/bin# export PATH
root@alibaba:/bin# apt-get install vim

回车后显示如下图
