今天在远程主机上安装tnvm，执行

wget -O- https://raw.githubusercontent.com/aliyun-node/tnvm/master/install.sh | bash

时出现

--2020-07-03 10:05:21--  https://raw.githubusercontent.com/aliyun-node/tnvm/master/install.sh

解决方法

1. wget后面添加--no-check-certificate

   wget --no-check-certificate -O- https://raw.githubusercontent.com/aliyun-node/tnvm/master/install.sh | bash
   

2. 安装ca-certificates

   apt-get install ca-certificates -y
   

   或者是

   apt-get install ssl-cert
