Not able to install it on Windows

Ninguém assumiu esta issue ainda.

When I tried to `npm install javasciprt-precommit`, it gave me an error:

```

> javascript-precommit@0.0.8 postinstall C:\gitlib\javascript-precommit
> ./bin/postinstall.js

'.' 不是内部或外部命令，也不是可运行的程序
或批处理文件。

npm ERR! Windows_NT 6.1.7601

```

The chinese character in the error log above means '.' is not a valid command.

I could fix this by modify the package.json from

```
"scripts": {
"postinstall": "./bin/postinstall.js",
"uninstall": "./bin/uninstall.js"
},
```

to

```
"scripts": {
"postinstall": "node ./bin/postinstall.js",
"uninstall": "node ./bin/uninstall.js"
},
```

Could you please help fix this? Thanks for your great work :smile:

Comece revisando package.json e os scripts bin/postinstall.js e bin/uninstall.js referenciados. Verifique se npm install e npm uninstall invocam esses scripts com sucesso no Windows e confirme que o comportamento existente do hook precommit permanece inalterado.
