rspec error messages

If you get this:


`require_relative': cannot load such file -- path (LoadError)

Do this:

Double-check that the files referenced by all your "require_relative" exist.
Also check that the spelling is correct and matches both ways.

If you get this:


Deprecation Warnings:



Using `should` from rspec-expectations' old `:should` syntax without explicitly enabling the syntax is deprecated. Use the new `:expect` syntax or explicitly enable `:should` with `config.expect_with(:rspec) { |c| c.syntax = :should }` instead.

Do this:

Replace "@book.should be_an_instance_of Book" with:

expect(@book).to be_an_instance_of Book

This is due to deprecation of the "should" syntax.

[SOLVED] Uncaught TypeError: Cannot set property 'innerHTML' of null

This happens when your innerHTML code is trying to insert into a html element/tag that doesn't exist or named differently.

The code below will produce error - the HTML doesn't have an element with the id "result":

HTML -



<body> 

<header></header>

  <div id="main">

  </div>

  <footer></footer>



  <script>

     var person = {

         firstName: "John",

         lastName : "Doe",

         id       : 5566,

         fullName : function(c) {

            return 'My name is ' + this.firstName + " " + this.lastName;

         }

     };

     document.getElementById("result").innerHTML = person.fullName ();

  </script>

</body>

This will work:

 <body>

<header></header>

<div id="main">

</div>

<footer></footer>



<script>

  var person = {

      firstName: "John",

      lastName : "Doe",

      id       : 5566,

      fullName : function(c) {

         return 'My name is ' + this.firstName + " " + this.lastName;

      }

  };

  document.getElementById("main").innerHTML = person.fullName ();

  </script>

</body>

[SOLVED] Uncaught Error: Bootstrap's JavaScript requires jQuery

This is quite a simple error you might encounter even when you've already included both jquery and bootstrap.js files.

Solution: Re-arrange the order of script tags in html file so that jquery is at the top, and bootstrap.js is anywhere after the jquery.js file.

This will cause the "uncaught error":

  <!-- js libs -->

  <!-- twbs jquery underscore backbone -->

  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script>

  <script src="/js/lib/jquery-1.11.2.js"></script>

  <script src="http://documentcloud.github.com/underscore/underscore-min.js"></script>

  <script src="http://documentcloud.github.com/backbone/backbone-min.js"></script>

Problem solved:



  <!-- js libs -->

  <!-- jquery twbs underscore backbone -->

  <script src="/js/lib/jquery-1.11.2.js"></script>

  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script>

  <script src="http://documentcloud.github.com/underscore/underscore-min.js"></script>

[SOLVED] Wordpress Edit Image Cannot Crop Issue

Earlier I wrote about this stubborn problem where Wordpress was refusing to let me use the built-in crop and rotate image editing features even after a clean install.

After I attempted to install a new media-handling plugin, to kind of skip Wordpress altogether when it comes to image editing, I was notified that I didn't have the GD graphics library installed with php.

So I quickly installed it. You must restart the web server after that.

Read more:

GD Library https://libgd.github.io/pages/faq.html
Cyberciti's how-to page http://www.cyberciti.biz/faq/ubuntu-linux-install-or-add-php-gd-support-to-apache/
The media-plugin I installed was "WP Optimize By xTraffic". For basic cropping you can rely on Wordpress' built-in image control and editing features.

Atom Package Update Failed For Emmet, Git-Plus, Minimap

Encountered the following error using the Atom text editor in my mac. I'm using a 2012 Macbook Pro running Yosemite (which is a slow OS compared to mountain lion or lion or snow leopard).

Package update failed using Atom's package update menu.

Issuing "apm install emmet" gave me this error:

EACCES, unlink '/Users/pacesferry/.atom/packages/emmet/.npmignore'

Solution: sudo the command.

So either
sudo apm install emmet
or
sudo apm update emmet

Sphinx Search WARNING: key 'sql_query_info' was permanently removed from Sphinx configuration. Refer to documentation for details.

I'm using Sphinx 2.2.5 and the gem Thinking-Sphinx.

Every time I run the command RAKE TS:REBUILD I will get the following warning messages. How annoying. You'd be pleased to learn that these warnings are harmless as they are due to deprecation.

WARNING: key 'sql_query_info' was permanently removed from Sphinx configuration. Refer to documentation for details.

WARNING: key 'charset_type' was permanently removed from Sphinx configuration. Refer to documentation for details.

WARNING: key 'enable_star' was permanently removed from Sphinx configuration. Refer to documentation for details.

cap production deploy errors

If you get this:



cap aborted!

SSHKit::Runner::ExecuteError: Exception while executing on host my-app-name.com: git exit status: 2

git stdout: Nothing written

git stderr: fatal: Not a valid object name

tar: This does not look like a tar archive

tar: Exiting with failure status due to previous errors

It's probably due to deploy.rb attempting to deploy a branch that is empty on remote ie has not commits yet.

Solution: Try pointing to a branch with commits.
