我是一个新人用于散步。我尝试在Ubuntu中设置android，我使用Here进行了设置。但是我有像bellow.please这样的问题解决了这个问题吗？
var timeSlotModel = require('../models/time_slot').model;
var Booking = require('./booking');
Booking.getBookings({}, function(err, bookings) {
if (err) {
console.error(err);
} else {
timeSlotModel.find({start: bookings.start}, function(err, slots) {
if (err) {
console.error(err);
} else {
return next(null, slots);
}
}
}
这些是显示的输出
MongooseError: Cast to number failed for value "undefined" at path "start"

答案 0 :(得分：1)
You got a permissions error. That means that your user account doesn't have access to something in your build path. i'd say start with:
bundle install
and go up the path from there.
you should eventually find that user/group permissions somewhere in there don't belong to you. once you find the culprit use bundle install
bundle update
bundle exec bundle install
bundle update json
gem install json
gem install json -v '1.8.6'
however, you also got told that there is a log file at `componentDidMount(){
var owner;
for(var i = 0; i < this.props.categoryId.length; i++) {
if (this.props.categoryId[i].num === this.props.content.categories[0]) {
owner = this.props.categoryId[i].category;
this.setState({
catname: owner
})
break;
}
}
var theContent = this.props.content.content.rendered;
var output = $(theContent).find("img").map(function() {
return this.src;
}).get();
this.setState({
postImages: output
});
}
click(){
this.updateActive();
this.props.fix();
}
render() {
if (this.props.className === this.state.catname) {
return (
<div >
{ this.props.className === this.state.catname &&
<article className={`${this.state.catname}`} >
{this.state.postImages.map((image, i) =>
<ImageContain key={image} image={image} fix={this.props.fix} />
)}
</article>
}
</div>
);
} else {
return null;
}
}`
,
try ls -la /home/user/android/Android/Sdk/build-tools/25.0.1/aapt /tmp/PZHyT7 and post the results.
