ubuntu删除了python恢复_Ubuntu16.04 不小心删除 /usr/bin/python解决办法

分析：

网上给出的方法都是修改/usr/bin/yum文件的头部，把/usr/bin/python修改为/usr/bin/python2.x就可以了，但我的情况是我把旧的python已经卸载了，于是尝试重新安装2.7版本的python

python版本下载地址：https://www.python.org/ftp/python/
下载2.7.5
wget https://www.python.org/ftp/python/2.7.5/Python-2.7.5.tar.xz
解压缩
tar -xvf Python-2.7.5.tar.xz
创建路径安装路径
mkdir /usr/local/python
切换到安装路径执行
./configure --prefix=/usr/local/python/
make
make install
创建软连接
ln -s /usr/local/python/bin/python /usr/bin/python
安装完成以后依旧报原有的错误，和上图一样；这有点烦银了，继续找办法。。。

发现有博客讲下载python以及yum的rpm包，行不行先试一试，

创建脚本下载相关的rpm包

 

mkdir /opt/packages/python
vim pull.sh
