将非核心npm库导入Angular 2 App [英] Import non-core npm Library into Angular 2 App

问题描述

我是Angular 2的新手，我很难导入Regression npm模块 https: //www.npmjs.com/package/regression 在Angular 2应用程序中使用线性回归函数.我的构建包括Angular 2，Webpack和TypeScript. 到目前为止，我已经npm install regression并将script标记包含在index.html

Hi I am new to Angular 2 and I am having a hard time importing the Regression npm module https://www.npmjs.com/package/regression within my Angular 2 application to use the Linear Regression function. My build consists of Angular 2, Webpack, and TypeScript. So far I have npm install regression and included the script tag within my index.html

<script src="node_modules/regression/src/regression.js"></script>

我的App.Module中也有回归

I have also Regression within my App.Module

import * as Regression from 'regression;

这是我尝试使用回归函数的方法，但是它表明找不到该函数:

This is how I am trying to use the regression function but it is showing that the function cannot be found:

let actualXY = [];
for (var j = 0; j <= 11; j++) {
        let entry = [];
        entry[0] = j+1;
        entry[1] = m.actuals[j];
        actualXY[j] = entry;
}
var result = regression('linear', actualXY);

我是否缺少导入Regression包的任何步骤，或者这根本不可能吗?

Is there any steps I'm missing to import the Regression package or is this simply not possible?

推荐答案

如您的导入所示:import * as Regression from 'regression;，因此您应该使用Regression而不是regression，因此应该使用Regression('linear', actualXY);.此外，在导入的regression之后还有quote缺失. PS :我不知道什么是回归，但是我已经从逻辑的角度回答了.

As your import illustrates : import * as Regression from 'regression; , thus you should use Regression not regression, so it should be Regression('linear', actualXY); instead. Also, there is a missed quote after the imported regression. PS: I do not know what is regression but I've answered from a logical point of view.
