The react-native local-cli does a check to see if it is being run from a global install or not. If running from a global install, an error is printed and the CLI exits.
This check for a global install does not work on Windows. The check of `process.argv` does not contain the expected `node_modules/.bin/react-native`. It instead contains a direct path to the `wrong-react-native.js` file, as determined by the `node_modules/.bin/react-native.cmd` entry point.
This update will, on Windows platforms, do a global check by instead looking for the existence of a package.json above the node_modules. If not found, we assume a global install and print the error.
In a react-native project, I originally tried running the local react-native cli:
```
> yarn react-native --version
yarn run v1.3.2
$ E:\myproject\node_modules\.bin\react-native --version
Looks like you installed react-native globally, maybe you meant react-native-cli?
To fix the issue, run:
npm uninstall -g react-native
npm install -g react-native-cli
error Command failed with exit code 1.

```
I replaced the `wrong-react-native.js` with the modified version and reran the command:
```
> yarn react-native --version
yarn run v1.3.2
$ E:\myproject\node_modules\.bin\react-native --version

Summary:
IIRC we made `wrong-react-native` to warn people in case they installed `react-native` globally (instead of `react-native-cli` what the guide suggests). To do that we added `bin` entry to React Native's `package.json` that points to `local-cli/wrong-react-native.js`
However, this means that if we have a project that uses `react-native` package and has call to `react-native` CLI inside its package.json, npm will execute *local* override (which just prints a confusing in this context error message).
In fact, the template we generate with `react-native init` has `react-native start` as `start` script, which makes it useless. Let's fix it by making `wrong-react-native` script smarter – it can detect that it has been executed from local `node_modules` and run the actual CLI.

Summary:
When used in automation, `wrong-react-native` can cause problems because it does not
report the issue via exit code.
