在部署项目环境时，发现报如下错误

[root@izbp1gb52c9au4ljt3u7w8z test]# wget http://nginx.org/download/nginx-1.13.7.tar.gz 
-bash: wget: command not found
[root@izbp1gb52c9au4ljt3u7w8z test]#

看到了这个错误，我就去安装 wget

[root@izbp1gb52c9au4ljt3u7w8z test]# yum -y install wget
Loaded plugins: fastestmirror

Package wget-1.14-18.el7_6.1.x86_64 already installed and latest version
Nothing to do
[root@izbp1gb52c9au4ljt3u7w8z test]# 

发现 wget 已经存在，我蒙蔽了，这咋回事啊

# yum remove wget -y

没办法，重装

yum -y install wget

再次下载
