Answer 1

What is the Node.js version? Try upgrading to v4 or v5, or use npm i --registry=https://registry.npm.taobao.org

directly

Answer 2

node --version
Check the version of your node. If it is too low, it may not support the const variable declaration method, because this is the syntax of es6

Answer 3

It should be that the node version is too low. It is recommended to use NVM to manage the node version:

$ git clone git@github.com:creationix/nvm.git ~/.nvm
$ source ~/.nvm/nvm.sh
# 安装
$ nvm install v0.12.0
# 显示当前本地安装的所有 Node.js
$ nvm ls 
# 显示服务器所有可用的 Node.js
$ nvm ls-remote
# 本地可用的 Node.js 中使用 0.12.0
$ nvm use 0.12.0
# 设置每次启动默认版本
$ nvm alias default 0.12.0

In addition, nvm install node you can install the latest node.
