pip 显示错误“lsb_release -a”返回非零退出状态 1

Question

我正在尝试使用 pip 安装软件包，但它抛出错误。

我用过的命令，

 sudo pip install selenium

它显示的错误，

我到处搜索，但没有解决这个问题的方法。它最近开始表现得像这样。此外，软件更新程序停止工作。不确定是否与此有关。我正在使用 Ubuntu 14.04 LTS 和 python 2.X

啊经典 lsb_release 问题。我已经多次与这个问题作斗争。问题是您的默认 Python 实现正在尝试使用 Python 3，但是 lsb_release 需要 Python 2。要解决此问题，请执行以下操作：

• 打开 /usr/bin/lsb_release （确保使用 sudo 或以 root 身份打开！）
• 将第一行编辑为 #! /usr/bin/python2.7
• 保存文件

现在您可以再次使用 pip，一切都应该没问题。

2019 年 5 月更新：默认情况下，较新版本的 Linux 随附 Python3。如此处的评论所述，您可能只需要使用特定版本的 Python 3。
