试图让nerdamer参与React Native项目

Question

I can't get nerdamer to work correctly in my react native project. When I write the functions for nerdamer the way it is shown on nerdamer's website it gives me either undefined is not object or nerdamer is not a function.

I have tried rewriting the nerdamer functions as nerdamer.nerdamer(equation) . Also writing it as nerdamer.solve(equation, variable) and nerdamer.Solve.solve(equation, variable) .

import {nerdamer, Algebra, Calculus, Solve, Extra} from "nerdamer";

equation = nerdamer('f=m*a');
solution = equation.solveFor('a');
console.log(solution.toString());

When I use this code in a browser it prints a=f*m^(-1) . But when I test it in my react native app it throws

(0,_nerdamer.nerdamer) is not a function. (In '(0,_nerdamer.nerdamer)('f=m*a')','(0,_nerdamer.nerdamer)' is undefined)

How am I supposed to be writing my nerdamer code in my project?

Answer 1

I was able to use nerdamer like this (you need to import them above everything) :

import nerdamer from'nerdamer/nerdamer.core.js'
import 'nerdamer/Algebra.js'
import 'nerdamer/Calculus.js'
import 'nerdamer/Solve.js'

Nerdamer use module.export & you can import it easily like a regular module. Since there is no module.export in other modules, you can't import them like this but the codes is needed. I tested the example below from its docs & it worked :

let sol = nerdamer.solveEquations(['x+y=1', '2*x=6', '4*z+y=6']);
console.log(sol.toString());
//x,3,y,-2,z,2
