JSPM Angular2-rc2 build animate error

Quindi, creare il mio progetto angular2 con JSPM per il rilascio: jspm bundle-sfx app dist/main.sfx.js. Tutto bene, finché non provo a caricare l'app costruita nel browser. Questo è l'errore che ottengo: `JSPM Angular2-rc2 build animate error

EXCEPTION: Error during instantiation of AnimationDriver! (ViewUtils -> RootRenderer -> DomRootRenderer -> AnimationDriver

che cosa potrebbe causare un errore del genere?

Ho avuto lo stesso errore quando ho associato l'app angular2 con il webpack. Si è scoperto che nel mio caso si lamentava che document.body è null. Ciò accade quando includi i tuoi script nella sezione body prima della sezione body e nello script che tenta immediatamente di operare con document.body.

mio index.html è stato così:

<!DOCTYPE html> 
<html> 
<head> 
    <base href=""> 

    <title>Legal Review</title> 
    <meta charset="UTF-8"> 
    <meta name="viewport" content="width=device-width, initial-scale=1"> 
    <meta http-equiv="X-UA-Compatible" content="IE=edge"> 

    <script src="build/thirdparty.js"></script> 
    <script src="build/app.js"></script> 
</head> 

<body> 
    <app-component> 
     Loading... 
    </app-component> 
</body> 

</html>

script Così, ho spostato come questo:

<!DOCTYPE html> 
<html> 
<head> 
    <base href=""> 

    <title>Legal Review</title> 
    <meta charset="UTF-8"> 
    <meta name="viewport" content="width=device-width, initial-scale=1"> 
    <meta http-equiv="X-UA-Compatible" content="IE=edge"> 
</head> 

<body> 
    <app-component> 
     Loading... 
    </app-component> 

    <script src="build/thirdparty.js"></script> 
    <script src="build/app.js"></script> 
</body> 

</html>

E ora funziona benissimo.

Grazie. Questo ha funzionato per me usando JSPM bundle-sfx. Il messaggio di errore era piuttosto criptico e stavo basando la mia posizione sul tag script sull'esempio di avvio rapido dei documenti Angular2 ... –

grazie mille, non potevo capire perché questo errore sembrava casuale! – Gnujeremie
