ubuntu22.04环境中安装pylint

[sudo apt-get install python3-pip](#sudo apt-get install python3-pip)
[sudo aptitude install python3-pip](#sudo aptitude install python3-pip)
[sudo pip install pylint](#sudo pip install pylint)

sudo apt-get install python3-pip

在安装pylint的时候，需要使用pip命令，在ubuntu22.04环境中命令如下：

复制代码

$ sudo apt-get install python3-pip

这里提示报错导致安装不能继续，尝试了很多方法去解决这个问题，其实这个问题可以方便地通过aptitude命令来进行解决。

sudo aptitude install python3-pip

$ sudo aptitude install python3-pip

Accept this solution? [Y/n/q/?] Y

这里要选择Y，接着就可以正常安装。安装完毕使用whereis pip命令检查也符合预期。

sudo pip install pylint

使用命令sudo pip install pylint进行安装，确认安装状态（不同时期版本号会有所差异）。
