Typescript TS5042 Build: Option 'project' cannot be mixed with source files on a command line
<p>I am receiving the following error across all typescript projects that I am trying run.</p>

<pre><code>TS5042  Build: Option 'project' cannot be mixed with source files on a command line.
</code></pre>

<p>I have downloaded a free Typescript Angular2 template, ran it and this error immediately pops up.</p>

<p>Has it got something to do with my global typescript installation?</p>
