在aliyun linux上npm install失败

今天在ESC上使用npm进行安装，出现以下错误：

npm ERR! code ETIMEDOUT
npm ERR! errno ETIMEDOUT
npm ERR! network request to https://registry.npmjs.org/pm2 failed, reason: 
npm ERR! network This is a problem related to network connectivity.
npm ERR! network In most cases you are behind a proxy or have bad network settings.
npm ERR! network 
npm ERR! network If you are behind a proxy, please make sure that the
npm ERR! network 'proxy' config is set properly.  See: 'npm help config'

解决办法：修改境像

npm config set registry https://registry.npmmirror.com

检查是否设置成功：

npm config get registry

再进行安装:

npm install pm2 -g

 

参考安装pm2
