NPM安装-意外的标识符

Question

我只是想在Mac上安装NPM（运行Mojave），每当尝试使用NPM命令时，都会收到相同的错误消息。

Jonathans-MacBook-Pro:~ jt$ npm install

/Users/jt/anaconda3/lib/node_modules/npm/bin/npm-cli.js:85
      let notifier = require('update-notifier')({pkg})
          ^^^^^^^^
SyntaxError: Unexpected identifier

    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:906:3

任何npm命令（即）都遇到相同的问题
