因此，我尝试使用 add-apt-repository 添加存储库，但收到此错误：
sudo add-apt-repository ppa:gijzelaar/opencv2
[sudo] password for foo:
Traceback (most recent call last):

from softwareproperties.SoftwareProperties import SoftwareProperties
ImportError: No module named softwareproperties.SoftwareProperties
像新手一样，我认为使用 apt 简单地卸载并重新安装 python-software-properties 是一个好主意。
重新安装后，我得到了这个：
foo@ubuntu:/$ sudo apt-get install python-software-properties

python-software-properties is already the newest version.

答案1
您必须执行其他操作来更改默认 Python 解释器的版本。
该命令ls -l /usr/bin/python应显示类似以下内容：
lrwxrwxrwx 1 root root 9 2011-05-12 23:59 /usr/bin/python -> python2.7
如果没有指向python2.7，但python3.2例如，你将默认的 Python 解释器修改为 3，这不是一个好主意，因为有一些向后不兼容的更改。要恢复 python2.7，你必须运行：
sudo ln -sf python2.7 /usr/bin/python
仅当 /usr/bin/python 实际上是一个符号链接时才执行此操作，如上面的输出所示ls。
