阿里云错误:用yum指令就会报错:下面这个是yum remove xz时:

Loaded plugins: fastestmirror  //装载这个插件
Setting up Remove Process
No Match for argument: xz 
Loading mirror speeds from cached hostfile
 * base: mirrors.cloud.aliyuncs.com
 * extras: mirrors.cloud.aliyuncs.com
 * updates: mirrors.cloud.aliyuncs.com
 * webtatic: us-east.repo.webtatic.com
Error: xz compression not available //这个很有诱导性,我一度认为是xz的问题,但当我尝试压缩和解压,发现xz可以正常工作
1 是查到大多数解决办法,不适用。2 是最终解决问题,确实是关闭这个插件,yum就可以正常更新了

使用yum命令报错File "/usr/bin/yum", line 30 except KeyboardInterrupt, e:说什么又语法错误,是因为程序是由python2

写的,而阿里云是python3 的库,没想到兼容的这么差。而且按照方法修改的时候注意,自己的版本:

/usr/bin

python
python2
python2.6
python2.6-config
python2.6.ori
python-config
