使用修补后的Qt运行任何版本的wkhtmltopdf时出现此JavaScript错误:
Warning: undefined:0 Error: [$injector:modulerr] Failed to instantiate module ng due to:
'undefined' is not an object
http://errors.angularjs.org/1.5.7/$injector/modulerrp0=ng&p1='undefined'%20is%20not%20an%20object
(我试图使用angularjs 1.5渲染页面。)
当我在没有修补Qt的情况下使用wkhtmltopdf版本时,我没有收到错误,一切正常。
我使用this heroku buildpack安装版本0.12.3并修补了Qt,我收到了此错误。
知道如何解决我的问题吗?我可以在没有修补Qt的情况下安装wkhtmltopdf,但似乎我必须编译它......

我终于设法使它适用于所有版本:我需要特殊版本的.bind()JavaScript函数polyfill:
var isFunction = function (o) {
return typeof o == 'function';
};
var bind,
slice = [].slice,
proto = Function.prototype,
featureMap;
featureMap = {
'function-bind': 'bind'
};
function has(feature) {
var prop = featureMap[feature];
return isFunction(proto[prop]);
}
// check for missing features
if (!has('function-bind')) {
// adapted from Mozilla Developer Network example at
// https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/bind
bind = function bind(obj) {
var args = slice.call(arguments, 1),
self = this,
nop = function() {
},
bound = function() {
return self.apply(this instanceof nop ? this : (obj || {}), args.concat(slice.call(arguments)));
};
nop.prototype = this.prototype || {}; // Firefox cries sometimes if prototype is undefined
bound.prototype = new nop();
return bound;
};
proto.bind = bind;
}
