Node.js: 找不到模块 'chai'

我正在尝试按照https://mochajs.org/的第一个示例进行操作。

已经执行了以下命令:

$ npm install -g mocha

得到以下结果:

C:\Windows\system32>npm install -g mocha
npm WARN deprecated [email protected]: Jade已更名为pug,请安装最新版本的pug而不是jade
npm WARN deprecated [email protected]: graceful-fs版本3及更早版本将在较新的node版本中失败。请尽快更新到graceful-fs@^4.0.0。
C:\Users\TestUser\AppData\Roaming\npm\_mocha -> C:\Users\TestUser\AppData\Roamin
g\npm\node_modules\mocha\bin\_mocha
C:\Users\TestUser\AppData\Roaming\npm\mocha -> C:\Users\TestUser\AppData\Roaming
\npm\node_modules\mocha\bin\mocha

├── [email protected] ([email protected], [email protected])
└── g[email protected] ([email protected], [email protected], [email protected])

还安装了chai(抱歉,我最初忘记提到它了)

C:\Windows\system32>npm install -g chai
[email protected] C:\Users\TestUser\AppData\Roaming\npm\node_modules\chai
├── [email protected]
├── [email protected]
└── [email protected] ([email protected])

这是代码:

var assert = require('chai').assert;
describe('Array', function() {
  describe('#indexOf()', function () {
    it('should return -1 when the value is not present', function () {
      assert.equal(-1, [1,2,3].indexOf(5));
      assert.equal(-1, [1,2,3].indexOf(0));
    });
  });
});

一直得到以下错误:

Error: 找不到模块'chai'
at Function.Module._resolveFilename (module.js:325:15)
at Function.Module._load (module.js:276:25)
at Module.require (module.js:353:17)

我做错了什么?
