推荐答案

您可能希望构建python3的virtualenv，然后在激活virtualenv之后安装python3的软件包.这样您的系统就不会混乱了:)

You may want to build a virtualenv of python3, then install packages of python3 after activating the virtualenv. So your system won't be messed up :)

这可能类似于:

virtualenv -p /usr/bin/python3 py3env
source py3env/bin/activate
pip install package-name
