CNPM 遇到use strict的问题

一、问题描述

[root@VM_123_144_centos node01]# cnpm install --save nodemailer

/usr/lib/node_modules/cnpm/node_modules/npminstall/bin/install.js:5
const debug = require('debug')('npminstall:bin:install');
^^^^^
SyntaxError: Use of const in strict mode.
    at Module._compile (module.js:439:25)
    at Object.Module._extensions..js (module.js:474:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:929:3

二、解决办法
删除node_modules文件夹

[root@VM_123_144_centos node01]# rm -rf /usr/lib/node_modules 

使用NVM重新安装最新版的nodejs

nvm install node

安装成功后，查看版本

[root@VM_123_144_centos node01]# nvm install node
v6.4.0 is already installed.
Now using node v6.4.0
[root@VM_123_144_centos node01]# node -v
v6.4.0

测试cnpm

[root@VM_123_144_centos node01]# npm install --save express
