我在修复一些问题时想知道我是否安装了 python3 “乘以”几个操作。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？
顺便说一下
python3 --version：
Python 3.6.9

由于您有一些 16.04 LTS 的剩余内容，因此您必须删除它的 Python 包：
sudo apt-get purge libpython3.4:amd64 libpython3.4-minimal:amd64 libpython3.5-minimal:amd64 python3.4 python3.4-minimal python3.5-minimal
然后删除准备好自动删除的软件包：
sudo apt-get autoremove --purge
您的输出正常。在我的 Ubuntu MATE 18.04.5 LTS 系统上，我有：
python3: /usr/bin/python3.6m /usr/bin/python3 /usr/bin/python3.6 /usr/bin/python3.6m-config /usr/bin/python3.6-config /usr/lib/python3 /usr/lib/python3.6 /usr/lib/python3.5 /usr/lib/python3.8 /usr/lib/python3.7 /etc/python3 /etc/python3.6 /usr/local/lib/python3.6 /usr/include/python3.6m /usr/include/python3.6 /usr/share/python3 /usr/share/man/man1/python3.1.gz
并且正常工作。
因此，我从存储库安装了 Python 3。 中的 python 文件夹/usr/local是由 创建的pip3，因此它们也是安全的。
