This happened to me because I was importing my code in the <code>head</code> tag, so it was potentially running and attempting to bootstrap before the DOM was ready.

You can either move the script to the bottom of the <code>body</code> tag, or put the bootstrap code within an event listener:

<pre><code>document.addEventListener("DOMContentLoaded", function(event) {
 bootstrap(AppComponent);
});
</code></pre>

or:

<pre><code>&lt;!DOCTYPE html&gt;
&lt;html&gt;
 &lt;head&gt;
 &lt;meta charset="utf-8"&gt;
 &lt;title&gt;Example app&lt;/title&gt;
 &lt;/head&gt;
 &lt;body&gt;
 &lt;my-app&gt;&lt;/my-app&gt;
 &lt;/body&gt;
 &lt;script src="main.js" charset="utf-8"&gt;&lt;/script&gt;
&lt;/html&gt;
</code></pre>

I got same issue when I use Angular Universal. But it is because I am using <code>BrowserModule</code> in main.node.ts, the solution is

<pre><code> imports: [

<li>Go to app.module.ts (to main modules, in most cases this is a name)</li>
<li>Check if you have part "boostrap:" - if no add:

<code>bootstrap: [AppComponent]</code> // where AppComponent is your main component</li>
<li>Check if it works now, if not - go to AppComponent and check your selector. It should be same as tags in body in index.html</li>
</ol>

so index.html should contain something like this:

<pre><code>&lt;body&gt;
 &lt;app-root&gt;Loading...&lt;/app-root&gt;
&lt;/body&gt;
</code></pre>

where instead of <code>&lt;app-root&gt;</code> you should use selector from main AppComponent

I was updating an Angular 5.2 app to Angular 6.1 and run into similar issue. In this case the problem was that index.html file did not have <code>&lt;body&gt;</code> at all. It was instead included in the <code>my-app</code> component.

<pre><code>&lt;!doctype html&gt;
&lt;html lang="en"&gt;
&lt;head&gt;
 &lt;meta charset="utf-8"&gt;
 &lt;title&gt;Example&lt;/title&gt;
 &lt;base href="/"&gt;
 &lt;meta name="viewport" content="width=device-width, initial-scale=1"&gt;
 &lt;link rel="icon" type="image/x-icon" href="favicon.ico"&gt;
&lt;/head&gt;
&lt;my-app&gt;&lt;/my-app&gt;
&lt;/html&gt;
</code></pre>

This used to work with Angular 5.2 (and earlier versions too) because in the generated index.html the script tags were placed at the end. After upgrade to 6.1 the script tags were instead placed in the beginning of the file (and I assume therefore executed before the <code>&lt;my-app&gt;&lt;/my-app&gt;</code> root element is actually present.

Solution was to move <code>&lt;body&gt;</code> into index.html. (It was originally placed in to the component because someone wanted to apply conditional classes to body element with <code>ngClass</code>.)

Non of the above answers resolved my issue .This is how solve the same kind of error.
You shouldn't have more than one component as Bootstarp component .So, Bootstrap array should have only one component .By mistake I put 4 components in bootstrap array.I removed those 4 components from there and put in entryComponents array(as shown in the code below).This helped me.

This happened to me when I changed the bootstrap component from <code>AppComponent</code> to a new component. When you change it you need to change it in the main <code>index.html</code> as well. <code>index.html</code> should contain the bootstrap component.

For example, if you change the <code>app-component</code> to <code>app-login</code> in <code>app.module.ts</code> in the bootstrap section then you should update your <code>index.html</code> like this

<pre><code>&lt;body&gt;
 &lt;app-login&gt;&lt;/app-login&gt;
&lt;/body&gt;
</code></pre>

sure you use app-routing module and must change the selector: 'my-app' to 'app-root' (file: app.component.ts)

The problem is when I run my app, it works fine. But when I refresh it, most of the time I get below msg. 

<blockquote>
 The selector "my-app" did not match any elements
</blockquote>

But the strange thing is that many times when I refresh my app it works also. 

So ultimately I have a strange behavior of my app and unable to figure this out. 
 Sometimes it works sometimes doesn't...

Any suggestion, can't come up with code???

Note : I don't have complex structure or components yet but simple implementation.

The selector "my-app" did not match any elements
