这些错误引用了python 3.7。我从源代码安装了python 3.7。我已经从/usr/bin和/usr/local/bin中删除了python 3.7。然而，上述问题尚未得到解决。默认版本python 3.5仍然有效，所以我可以在电脑上使用python3。
有人能建议我如何解决这些问题和我的电脑吗？我需要避免清理操作系统。
Ubuntu依赖于安装的特定版本的Python。在16.04中，/usr/bin/python必须为2.7，/usr/bin/python3必须为3.5。从源代码安装Python的make install步骤可以覆盖这些文件。值得庆幸的是，它们只是符号链接，所以修复它应该很容易。作为根：
# ln -sf python2.7 /usr/bin/python
# ln -sf python3.5 /usr/bin/python3
但是，如果您确实需要二进制文件，可以使用上面的链接。只需选择您的体系结构，然后选择镜像即可。或者使用apt download python python3(如果有效的话(。然后使用dpkg -i安装软件包。
然后将3.7安装回/usr/bin/python3.7，我相信您可以运行make altinstall。
