我到处搜索，但没有解决此问题的方法.最近开始出现这种情况.此外，软件更新程序停止工作.不确定是否与此有关.我使用的是 Ubuntu 14.04 LTS 和 python 2.X

I have searched everywhere, but there is no solution for this problem. It started behaving like this recently. Also, Software Updater stopped working. Not sure if it is related to that. I am using Ubuntu 14.04 LTS and python 2.X

推荐答案

啊，经典的 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 实现尝试使用 Python 3，但 lsb_release 需要 Python 2.要解决此问题，请执行以下操作:

Ahhh the classic lsb_release issue. I have battled this problem many times. The issue is that your default Python implementation is trying to use Python 3 but lsb_release requires Python 2. To fix this problem do the following:

• 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

• Open /usr/bin/lsb_release (Make sure you use sudo or open as root!)
• Edit the first line to be #! /usr/bin/python2.7
• Save the file

现在您可以再次使用 pip，一切都应该没问题了.

now you can use pip again and everything should be fine.

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.

UPDATE May 2019: Newer versions of Linux are shipping with Python3 by default. As noted in the comments here, you may just need to use a specific version of Python 3.
