做的一个heroku的文件。
大概的有这么几个文件
登录页面
登陆用的账户密码存储在json文件夹里，里面的账号才能使用
<!DOCTYPE html>
<html lang="en">
{{>head}}
<body>
<h1 class="login-title">login page</h1>
<div>
<form action="/login" method="post" class="login-form">
<div class="con">
<header class="head-form">
<h2>登陆</h2>
<p>登 陆 </p>
</header>
<br />
<div class="field-set">
<input class="form-input" id="email" type="email" name="email" placeholder="Username" autofocus />
<br />
<input class="form-input" type="password" placeholder="Password" id="password" name="password" />
<br />
<button class="btn log-in">登陆</button>
</div>
<div class="other">
{{#if message}}
<label class="message">{{message}}</label>
{{/if}}
</div>
</div>
</form>
</div>
</body>
</html>
显示页面，显示一些图片
<!DOCTYPE html>
<html lang="en">

message: 'Not a registered username.'
});

});
});
剩下的打包之类文件不好放，总之我的跑不起来。
有没有人能告诉我为什么跑不起来，给一个成功的样本文件和截图么？
跑不起来报错是什么，日志截个图
报什么错，我看看，
在自己主机上跑，错误代码就是“Uncaught SyntaxError: Unexpected identifier”
我在heroku上爬出来是这样的
