我正在多台计算机上测试 Python3 程序。为此，我需要安装一个带有pip3.
所以首先，我python3-pip在每台计算机上安装（每个人都在运行 Kubuntu 操作系统）。一切正常，然后我安装了我需要的软件包pip3，除了一台计算机之外，我设法做到了。
在那台计算机上，python3-pip显然安装成功，但是当我查找软件包时，出现此错误（翻译是自制的）：
Command «pip3» was not found, maybe you wanted to say:
The command «pip» from the package «python-pip» (universe)
pip3: command not found
编辑
结果dpkg -L python3-pip：
