我正在使用Koudoku gem将Stripe集成到我的rails应用程序中，当我加载捕获用户信用卡信息的页面时，Stripe javascript应该运行，但是，我的JS控制台显示以下错误:
Uncaught ReferenceError: $ is not defined
(anonymous function)
这是由Koudoku/Stripe提供的JS，当页面加载时应该运行:
<script type="text/javascript">
// All this code taken from Stripe's own examples at:
// https://stripe.com/docs/tutorials/forms .
function stripeResponseHandler(status, response) {
if (response.error) {
// show the errors on the form
$(".payment-errors").text(response.error.message).show();
$(".submit-button").removeAttr("disabled");
} else {
var form$ = $("#payment-form");
// token contains id, last4, and card type
// insert the token into the form so it gets submitted to the server
form$.append("<input type='hidden' name='subscription[credit_card_token]' value='" + response['id'] + "'/>");
form$.append("<input type='hidden' name='subscription[last_four]' value='" + response['last4'] + "'/>");
form$.append("<input type='hidden' name='subscription[card_type]' value='" + response['card_type'] + "'/>");
// and submit
form$.get(0).submit();
}
}
$(document).ready(function() {
console.log("testing log")
Stripe.setPublishableKey("<%= Koudoku.stripe_publishable_key %>");
// By default, don't show errors.
$(".payment-errors").hide()
$("#payment-form").submit(function(event) {
// disable the submit button to prevent repeated clicks
$('.submit-button').attr("disabled", "disabled");
Stripe.createToken({
number: $('.card-number').val(),
cvc: $('.card-cvc').val(),
exp_month: $('.card-expiry-month').val(),
exp_year: $('.card-expiry-year').val()
}, stripeResponseHandler);
// prevent the form from submitting with the default action
return false;
});
});
</script>
不用说，console.log("testing log")没有被记录。
我在我的应用程序的其他部分使用coffeescript，我在其他地方使用jQuery。这是我的Gemfile:

任何想法是什么导致这个问题和/或如何解决它?谢谢!
我能够通过将<%= javascript_include_tag "application" %>从application.html.erb中的<body>的底部移动到顶部来解决这个问题，以便它在<%= yield %>之前运行，这样jQuery在视图之前加载
