Did you try recovering your dependencies?

yes

Which terms did you search for in User Guide?

"Updating to New Releases", "Migrating from 2.0.0-next.xyz"

Environment

(paste the output of the command here)
faild to run create-react-app --info
Environment:
OS: Windows 10
Node: 8.11.4
Yarn: 1.5.4
npm: 5.6.0
Watchman: Not Found
Xcode: N/A
Android Studio: Not Found

react-scripts: 2.0.0-next.a671462c => 2.0.0

Steps to Reproduce

(Write your steps here:)

1. init project with react-scripts@2.0.0-next.a671462c

$ create-react-app app --scripts-version 2.0.0-next.a671462c

2. add dva and modify src/index.js

$ cd app
$ yarn add dva

// src/index.js
import React from 'react';
import dva from 'dva';
import createHistory from 'history/createHashHistory';

// 1. Initialize
const app = dva({
  history: createHistory(),
});

// 2. Plugins
// app.use({});

// 3. Register global model
// app.model(require('../models/index').default);

// 4. Router
app.router(() => <div>Test</div>);

// 5. Start
app.start('#root');

3. The project can be successfully started

$ yarn start
yarn run v1.5.1
$ react-scripts start

Note that the development build is not optimized.
To create a production build, use yarn build.

4. update react-scripts to 2.0.0, project can not work any more.

$ yarn add --exact react-scripts@2.0.0
$ yarn start
yarn run v1.5.1
$ react-scripts start
Starting the development server...

Here's my findings thus far:

Since there are two versions of @babel/runtime, one gets hoisted and the other sits next to react-scripts:

=> Found "@babel/runtime@7.0.0-beta.46"
info Has been hoisted to "@babel/runtime"
info Reasons this module exists
   - Hoisted from "dva#@babel#runtime"
   - Hoisted from "dva#dva-core#@babel#runtime"
info Disk size without dependencies: "1.47MB"
info Disk size with unique dependencies: "9.05MB"
info Disk size with transitive dependencies: "9.05MB"
info Number of shared dependencies: 2
=> Found "react-scripts#@babel/runtime@7.0.0"
info This module exists because "react-scripts" depends on it.
info Disk size without dependencies: "516KB"
info Disk size with unique dependencies: "556KB"
info Disk size with transitive dependencies: "556KB"
info Number of shared dependencies: 1
✨  Done in 1.29s.

(note: dva's is at root, react-scripts's is next to it)

webpack is set to look at node_modules, which I assume means it looks at react-scripts's node_modules instead of starting at the dva level.

create-react-app/packages/react-scripts/config/webpack.config.prod.js

Lines 185 to 193 in a73829f

	resolve: {
	// This allows you to set a fallback for where Webpack should look for modules.
	// We placed these paths second because we want `node_modules` to "win"
	// if there are any conflicts. This matches Node resolution mechanism.
	// https://github.com/facebook/create-react-app/issues/253
	modules: ['node_modules'].concat(
	// It is guaranteed to exist because we tweak it in `env.js`
	process.env.NODE_PATH.split(path.delimiter).filter(Boolean)
	),

x-ref: webpack/webpack#6505 (comment)

I make this assumption because the module missing is with react-scripts's version, not dva's version:

joes-mbp:test-next joe$ ls node_modules/@babel/runtime/
README.md     core-js/      core-js.js    helpers/      package.json  regenerator/
joes-mbp:test-next joe$ ls node_modules/react-scripts/node_modules/@babel/runtime/
LICENSE       README.md     helpers/      package.json  regenerator/
joes-mbp:test-next joe$

So, it appears our module resolution is searching in the wrong place, not starting at the level of the project it's currently resolved to.

react-scripts@2.0.1 is out. Please upgrade your dependencies and see if this is fixed.

My issue in #5103 (comment) is now solved with 2.0.1

[xiaosongxiaosong]

It has been fixed by upgrade react-scripts to 2.0.1.
