        在ubuntu20.04上执行如下命令，报错

root@ubuntu:/home/vpp# sudo pip3 install setuptools
Collecting setuptools
  Using cached setuptools-62.3.2-py3-none-any.whl (1.2 MB)
Installing collected packages: setuptools
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
launchpadlib 1.10.13 requires testresources, which is not installed.
Successfully installed setuptools-62.3.2
WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv

解决方法

        执行如下命令

python3 -m pip install launchpadlib

        然后重新安装

sudo pip3 install setuptools
