将D3 v4正确安装到Angular2中

Question

我已经看到很多关于将D3 v4正确安装到angular2中的不同页面,似乎有很多关于这个主题的不同意见.我正在使用angular2.0和typescript2.我无法正确安装所有内容,以便我的IDE和ts编译器可以正常查看所有部分.如果我从'd3'那里做了像import*那样的d3; 当我做d3.line()时,即使它在浏览器中正常运行并呈现图形线,我也会抱怨.我得到属性'line'在类型'd3'上不存在.当我从d3-selection导入select时,我也遇到了无法在select()上调用转换的问题.

我知道我必须在这里做错事但是我远远没有成为angular2的专家,因为我最近才把它拿起来.

Answer 1

您使用的是 d3 v4.2.x，但键入的是 v3.5.x。有关默认版本为何为 3.x 的说明，请参阅https://github.com/DefinitelyTyped/DefinitelyTyped/issues/11367 。

此 D3 标准包作为名称为 d3 的 UMD 模块发布。目前，由于其他库对同一目录中包含的旧版 D3 v3.x 定义（例如，plottable、nvd3）存在依赖关系，因此该标准包的定义无法在 DefinitiveTyped/types-2.0 中发布（请参阅已关闭的 PR #10453） 。

真诚地希望它仍然是一个临时解决方法，需要代表 D3 版本 4 的定义文件的开发人员可以按如下方式操作：

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

或者，如果它适合您的用例，您可以尝试 angular2 d3 服务：https://github.com/tomwanzek/d3-ng2-service
