Cannot find module 'enzyme/build/react-compat'

[DonGiulio]

I just installed chai enzyme on my app, using:

 npm install chai-enzyme --save-dev

and tried to import it in my DirectionsMap mocha-enzyme-chai-chai_enzyme test:

import React from "react";
import { shallow } from "enzyme";
import chai from "chai";
import chaiEnzyme from "chai-enzyme";

import DirectionsMap from "../DirectionsMap";

describe("<DirectionsMap/>", function() {
  const fron = { latitude: 20.0, longitude: 10.0 };
  const to = { latitude: 24.0, longitude: 14.0 };

  it("makes an Iframe", function() {
    const component = shallow(<DirectionsMap from={fron} to={to} />);

    console.log(component.debug());
    expect(component).to.matchSnapshot();

    const iframe = component.find("Styled(Iframe)");
    expect(iframe).to.have.length(1);
    expect(iframe).to.have.attr("url");
  });
});

chai.use(chaiEnzyme());

I'm getting this error though, it looks like there's an unresolved dependency:

What versions of chai-enzyme and enzyme are you using? Make sure npm ls exits successfully, or else nothing can be expected to work.

[DonGiulio]

indeed npm ls reports some failures:

npm ERR! peer dep missing: [email protected] || ^2.3.0, required by [email protected]
npm ERR! peer dep missing: react@^0.14.0 || ^15.0.0-0, required by [email protected]

Sounds like you have 0.8.0, but enzyme 3 requires 1.0.0-beta something.

Correct, see #199 for more information on support with enzyme 3
