Question

我刚刚发现了immutable.js。我想尝试一下它，习惯它的工作原理。真的很简单。甚至不需要编写代码，只需要关注交互地在节点外壳中。

我已经安装了它：

$ npm install immutable
npm WARN saveError ENOENT: no such file or directory, open '/home/xxxxxxx/node/immutable/package.json'
npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN enoent ENOENT: no such file or directory, open '/home/xxxxxxx/node/immutable/package.json'
npm WARN immutable No description
npm WARN immutable No repository field.
npm WARN immutable No README data
npm WARN immutable No license field.

+ immutable@3.8.2
added 1 package from 1 contributor and audited 1 package in 2.934s
found 0 vulnerabilities

...然后我尝试使用它。

$ node
> const { Map } = require('immutable');
ReferenceError: Map is not defined
    at Module._compile (internal/modules/cjs/loader.js:683:37)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:700:10)
    at Module.load (internal/modules/cjs/loader.js:599:32)
    at tryModuleLoad (internal/modules/cjs/loader.js:538:12)
    at Function.Module._load (internal/modules/cjs/loader.js:530:3)
    at Module.require (internal/modules/cjs/loader.js:637:17)
    at require (internal/modules/cjs/helpers.js:20:18)
$ node -v
v10.10.0
$ npm -v 
6.4.1

在理解我可能错过的内容方面提供一点帮助真的很酷。

TIA

更新：只是为了它，我尝试了这个：

$ sudo npm install immutable

现在它可以工作了 ???
