    <p>I had a Ruby on Rails app that used to work. I hadn't used it in a month or so, but then tried starting it up today with <code>rails s</code> and got the following error—in fact, I get this error when I try <code>rails -h</code> or <code>rails -v</code> or even <code>gem -h</code> or <code>sudo gem update --system</code> or anything having to do with <code>gem</code>.</p> <pre><code>NOTE: Gem::Specification#default_executable= is deprecated with no replacement.

How can I uninstall it all and reinstall it (without uninstalling my OS, man that would really suck)</p>

    1. COAlso, I ran "sudo gem update rails" right before this broke, even though I had already installed rails. (I wanted to update it.) I'm guessing that has something to do with it.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
