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：

$ sudo apt-get install python3-pip

E: Unable to correct problems, you have held broken packages.

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

注意这里一定要选择n，接着系统就会给出降版本的建议

2)     python3-pkg-resources [59.6.0-1.2ubuntu0.22.04.1 (now) -> 59.6.0-1.2 (jammy)]


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。
