undefined d3.scale in Typescript
提问by Rémy Letient
I'm new with Typescript (2 weeks), and I work on project to wrap the d3.js framework. I'm encountered a problem with the usage of "d3.d.ts", namespace, export module, import.
我是 Typescript 的新手（2 周），我正在从事包装 d3.js 框架的项目。我在使用“d3.d.ts”、命名空间、导出模块、导入时遇到问题。
My problem : When I try to use the d3.scale.linear(), I have the error in my browser console :
我的问题：当我尝试使用 d3.scale.linear() 时，我的浏览器控制台出现错误：
TypeError: d3.scale is undefined
The code :
代码 ：
/// <reference path="../typings/d3.d.ts">;
"use strict";
var linear = d3.scale.linear();
console.log("linear resolv !")
My compiler option (I've no error on the compilation process, but perhaps it's interesting) :
我的编译器选项（我在编译过程中没有错误，但也许很有趣）：
{
"files": [
"src/twod3/workspace.ts",
"src/twod3/component/basic.ts",
"src/twod3/component/data.ts",
"src/twod3/component/operation.ts",
"src/main.ts"
],
"compilerOptions": {
"noImplicitAny": true,
"target": "es2015",
"module":"commonjs",
"sourceMap":true
}
}
I try different import strategy without success.
我尝试了不同的导入策略，但没有成功。
The d3.d.ts
d3.d.ts
declare namespace d3 {
...
export module scale {
...
export function linear(): Linear<number, number>;
...
}
}
I don't understand the problem, thank you for your help.
没看懂问题，谢谢大家的帮助。

Be careful of the version for d3.jsIn version 4.2.1 d3.scale.linear(); gives the following error. TypeError: d3.scale.linear() scale is undefined
注意 d3.js版本在 4.2.1 版本中 d3.scale.linear(); 给出以下错误。类型错误：d3.scale.linear() 比例未定义
I fixed this error in version 4.2.1 by using d3.scaleLinear();
我在 4.2.1 版本中使用 d3.scaleLinear() 修复了这个错误；

I had a similar kind of issue .I had to match the D3 version ,that supported the in built methods for d3. Either match the version of the D3.js ,make sure u update your bower . Or match the in built methods for your current version .
我遇到了类似的问题。我必须匹配支持 d3 内置方法的 D3 版本。要么匹配 D3.js 的版本，确保你更新你的凉亭。或者匹配您当前版本的内置方法。
My supported version for d3.scale.ordinal is '3.5.17',previously i was at the latest version.
我支持的 d3.scale.ordinal 版本是“3.5.17”，以前我是最新版本。
