will be helpful for those in need Well, what about having a condition before your update?
Update - Never mind. Better way to accomplish this is via the query!
code :
"click .dislikeButton": function() {
    Posts.update({_id : this._id, postLikes : {$gt : 0}}, {
      $inc: {
        postLikes: -1
      }
    });
}

I hope this helps you . I got mongo collection documents which includes an array which includes bunch of other objects. This is for a simple chat app. , I think you mean to do this:
code :
{{#with getMessages}}
  {{#each messages}}
    <p class="{{#if isMine}}my-message{{/if}}">{{text}}</p>
  {{/each}}
{{/with}}

Template.reqMessages.helpers({
  getMessages: function () {
    var theReqId = FlowRouter.getParam("reqId");
    return Messages.findOne({reqId: theReqId});
  },
  isMine: function () {
    return this.from === Meteor.userId();
  }
});

this will help Solution: remove none standard characters from directory name!
This error seems to be frequent, but one of the reasons it can be caused is due to using none standard characters in the directory path in this case ÅÄÖ, the issue is resolved by renaming folder to AAA.
