我想知道在修复一些问题时是否已经通过几个操作安装了 python3“乘法”。whereis python3在我的 ubuntu 18.04 中输入
python3: /usr/bin/python3.6m /usr/bin/python3.6-config /usr/bin/python3.6m-config /usr/bin/python3.6 /usr/bin/python3 /usr/lib/python3 .7 /usr/lib/python3.6 /usr/lib/python3 /usr/lib/python3.8 /etc/python3.4 /etc/python3.6 /etc/python3.5 /etc/python3 /usr/local /lib/python3.6 /usr/local/lib/python3.5 /usr/include/python3.6m /usr/include/python3.6 /usr/share/python3 /usr/share/man/man1/python3.1 .gz
我必须删除一些东西吗？
顺便说一句：
