我在使用带有angular2项目的D3时遇到了问题。我不断收到错误，例如“时间未定义”或“时间不是D3类型的属性”。
我通过npm安装了d3并安装了它的输入：npm install d3 --save。
在我的组件中，我有import * as d3 from 'd3';，它能够很好地找到库。
我尝试过添加
"addons": [{ "d3" : "vendor/d3/build/d3.js"}], packages": [{ "d3" : "vendor/d3/build/d3.js"}],
在angular-cli.json中。都没有工作。
package.json包含以下dev依赖项：
"devDependencies": {
"@types/d3-array": "^1.0.5",
"@types/d3-axis": "^1.0.5",

我在我的应用中使用此示例：http://codepen.io/stefanjudis/pen/gkHwJ。我究竟做错了什么？感谢

您作为基础使用的示例是http://d3js.org/d3.v3.min.js引用D3 v3，而您的应用正在使用D3 v4，它在API中有重大变化。
d3.time不再存在，因此您必须将代码调整为新API。例如，您在链接的Codepen示例中的第82行：
var parse = d3.time.format( '%Y-%m-%d' );
必须转换为：
var parse = d3.timeFormat( '%Y-%m-%d' );
正如你可以从主要D3回购index.js上的module export或d3 time format module的相关自述文件中看到的那样。
为每个过时的语法（例如d3.scale.linear现在是d3.scaleLinear）进行冲洗并重复，保留上述index.js文件作为参考，我想您将摆脱所有错误
