Anaconda3 安装报错 bunzip2: command not found

报错信息

Anaconda3-5.3.1-Linux-x86_64.sh: line 353: bunzip2: command not found
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors

解决方法和原因

由于系统缺少bunzip2包造成的，通过yum安装bzip2包来解决

yum install bzip2

分析和解决过程

可能是由于缺少bunzip2包导致的，先尝试安装这个包：

[root@localhost ~]# yum install bunzip2
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirrors.aliyun.com
 * extras: mirrors.aliyun.com
 * updates: mirrors.aliyun.com
No package bunzip2 available.
Error: Nothing to do

发现没找到这个包。百度下这个包：

• bunzip2，.bz2文件的解压缩程序。可解压缩.bz2格式的压缩文件。bunzip2实际上是bzip2的符号连接，执行bunzip2与bzip2 -d的效果相同

再次尝试bzip2包名

[root@localhost ~]# yum install bzip2
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirrors.aliyun.com
 * extras: mirrors.aliyun.com
 * updates: mirrors.aliyun.com
