不知不觉中，我删除了（根）目录中的 python 文件夹/，因此当我尝试运行 python3 时出现此错误。
我python3.2.3通过手动下载和使用read me文件安装的方式重新安装了版本。仍然面临同样的问题。

有解决办法吗？还是我应该重新安装操作系统
注意：如果可以打开 3.3（或更高版本）而不是 3.2.3，我们将非常欢迎
编辑1：当我尝试使用时sudo apt-get install python3，它说python3已经是最新版本。
答案1
我再次找到了解决方案。
当我通过各种链接寻找时，最终找到了这个关联。
只需重新安装该python3版本并输入hash -r以下命令即可恢复该版本。
cd "to the directory where downloaded python is"
./configure
make
make test
sudo make install
hash -r
