在Angular2中正确安装D3 v4

Question

我看过很多关于如何正确地将D3 v4安装到angular2中的不同页面，似乎在这个主题上有很多不同的意见。我正在使用angular2.0和typescript2。我很难正确地安装所有东西，以便我的IDE和编译器看到所有没有错误的部分。如果我做了import * as d3 from 'd3';当我执行d3.line()时，即使它在浏览器中运行良好并呈现图形线，它也会抱怨。我得到属性'行'不存在类型' d3的类型'。我也遇到了一些问题，当我从d3-selection导入select时，我不能在select()上调用transition。

我知道我在这里一定做错了什么，但是我远不是一个angular2的专家，因为我最近才开始学习它。

Answer 1

您使用的是v4.2。X的d3，但类型是v3.5.x。关于为什么默认版本是3.x的解释，请参阅https://github.com/DefinitelyTyped/DefinitelyTyped/issues/11367。

这个D3标准包作为一个名为D3的UMD模块发布。目前，这个标准包的定义不能在DefinitelyTyped/types-2.0中发布(参见关闭的PR #10453)，因为其他库在遗留D3 v3上存在依赖。X定义(例如，plottable, nvd3)包含在同一目录中。

真诚地希望它仍然是一个临时的解决方案，需要代表D3版本4的定义文件的开发人员可以按照以下步骤进行:

安装包含D3标准包的D3模块的模块级定义，例如使用npm install @types/d3-selection --save

或者，如果它适用于你的用例，你可以尝试angular2 d3服务:https://github.com/tomwanzek/d3-ng2-service

Answer 2

我在自定义area-cart.component.ts中执行import * as D3 from 'd3';，编译器没有报错。

在<<p> strong>包。json:

"@types/d3": "^3.5.38",
"d3": "^3.5.17",

版本3似乎运行良好。你真的需要D3 v4吗?

Answer 3

您可以尝试:

import * as d3selection from 'd3-selection';
import 'd3-transition';
d3selection.select(...)
