--description--

使用包管理器的最大原因之一是它们强大的依赖管理特性。在新的计算机上开始一个项目时不用手动确认你已安装所有的依赖npm 会自动为你安装它们。但是 npm 如何准确的知道你项目需要哪些依赖呢?我们来看看 package.json 中 dependencies 这一部分。

在 dependencies 这一部分,你的项目需要按照下面这种格式来存储这些依赖包:

"dependencies": {
  "package-name": "version",
  "express": "4.14.0"
}

--instructions--

在 package.json 的 dependencies 字段中添加一个版本号为 2.14.0 的 moment 包。

Moment 是一个非常方便的库,它用来处理时间和日期。

--hints--

'dependencies' 应该包含 'moment'。

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/package.json').then(
    (data) => {
      var packJson = JSON.parse(data);
      assert.property(
        packJson.dependencies,
        'moment',
        '"dependencies" does not include "moment"'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

'moment' 的版本应该是 '2.14.0'。

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/package.json').then(
    (data) => {
      var packJson = JSON.parse(data);
      assert.match(
        packJson.dependencies.moment,
        /^[\^\~]?2\.14\.0/,
        'Wrong version of "moment" installed. It should be 2.14.0'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
