问题 I have downloaded the Honeybadger webpack example and run bundle install . I don't have any errors in terminal, yet get the following when I start my server: Webpacker can't find application.js in /Users/admin/Documents/sourcemap/honeybadger-rails-webpacker-example/public/packs/manifest.json. Possible causes: 1. You want to set webpacker.yml value of compile to true for your environment unless you are using the `webpack -w` or the webpack-dev-server. 2. Webpack has not yet re-run to reflect

问题 I've seen different kind of problems around, but I'm fighting with this for a whole day, so please give me some help :) Short story : I have different PATH variable in System Variables panel and cmd. Can't run exe files? Longer story : I'm trying to install Ruby. Tried with different versions, but the problem is the same: I have my PATH value updated, Ruby is there. BUT when using it from cmd, ruby is not recognized. echo %PATH% gives different value from the one in Environment Variables

问题 I'm writing Logger and got problem with automatic adding class name, from which I called print_log method. For example something like this: class Logger def self.print_log(string) puts Time.now.strftime('%T | ') + *caller_class_name_here* + ' - ' + string end end class MyClass def initialize Logger.print_log 'called .new() method' end end As result of calling MyClass.new method I wanna see in output: 14:41:23 | MyClass - called .new() method I'm sure it's possible to do using caller , but yet

问题 I´m willing to use Gruff to render some graphics inside prawn documents. I want to avoid the delay of writing images to the disk only for them to be read by Prawn. Gruff offers the to_blob method that renders the graph image as a blob in memory, but looking at the prawn manual image section, it only gives us a way to render images directly from files. Am I missing something? Is there a way to render it from memory? 回答1: You should be able pass the image data as a StringIO require 'stringio'
