问题 I have installed Meteor on Windows 8.1 - 64 bit to continue developing an existing meteor app. But, I cannot start it. Problem I run "meteor run": it starts proxy, MongoDB, selects packages, and after the last step, "Building the application", I get an error which I cannot explain (see stack trace). Then, it keeps trying to build the app, and gives the same errors over and over again. Strange things : the exact same project works just fine on Ubuntu and Mac OS - now I want to use Windows 8.1

问题 I am trying to detect a mouseup outside of a window in Meteor.

Should give you the behavior you're looking for. var layoutMouseUpHandler = function(e) { console.log('window.mouseup')

问题 How do you find the current Session Id on the client? I am able to get what seems like the last session id, not the current session id. console.log(Meteor.default_connection._lastSessionId) 回答1: The wording for this is a bit confusing, but _lastSessionId is the current session id. It is only called this because if the client is disconnected and seeks to reconnect it wants to re-establish the session with the last session id. The client would reconnect with a message like this : {"msg":

问题 This question already has answers here : How can I get the index of an array in a Meteor template each loop? (6 answers) Closed 4 years ago .
