错误：找不到模块“ reative-native” /未找到模块：错误：无法解析模块“ react-native-web”

Question

Alright, I am desperately trying to install a branch of react-native-web that has a functioning ListView component. This branch , specifically.

I installed it into the project directory like so: npm install --save react@0.14 react-dom@0.14 https://github.com/IjzerenHein/react-native-web/tarball/feaure-listview2

Installing directly from react-native-web doesn't seem to have this issue.

this is what index.web.js looks like:

import React from 'react'

import {
AppRegistry,
Component,
...
} from 'react-native';

class App extends Component {
...
}

// App registration and rendering
AppRegistry.registerComponent('App', () => App);
AppRegistry.runApplication('App', { rootTag:     document.getElementById('react-root') });

Here is what the console tells me (part of it, way too much text in there!):

[Error] ./index.web.js

The problem is, that they have a build process. That way there are files used / expected that are ignored in git, but within the npm export.

The easiest way to overcome this is to clone the repository, check out the given branch, run the build and depending on if you have a large team either use npm link to link the local repository or remove dist/ from the .gitignore and push the build files to the branch.
