Babel 7 is incompatible with Babel 6. Therefore your entire project must rely on Babel 7. If you check the stack trace you might see references to `node_modules/babel-core`. This means that your project has Babel 6 dependencies.</p>\n<h2>Troubleshooting</h2>\n<p>Make sure that you've installed all the correct babel 7 dependencies, e.g.:</p>\n<ul>\n  <li>@babel/core instead of babel-core</li>\n  <li>@babel/cli instead of babel-cli</li>\n  <li>@babel/preset-env instead of babel-preset-env</li>\n</ul>\n<p>In my case, I had installed babel-cli globally (e.g. npm i -g babel-cli). This is not recommended. Babel-cli should be installed locally in dev-dependencies with:</p>\n<pre><code>npm i @babel/cli --dev</code></pre>\n<p>With a local install you can be confident that you're really using Babel 7 cli instead of Babel 6 cli.</p>\n<h2>Other Issues</h2>\n<p>NextJs, for example, depends on Babel 6. Therefore it's currently impossible to use Babel 7 in a Nextjs project.</p>\n<p>Babel 7 was only recently released and in time more projects will adopt Babel 7.</p>\n<h2>Further Reading</h2>\n<ul>\n  <li><a href=\"https://github.com/babel/babel/issues/7110 &quot;Module build failed: TypeError: Cannot read property &amp;apos;loose&amp;apos; of undefined&quot;\">Module build failed: TypeError: Cannot read property 'loose' of undefined</a></li>\n  <li><a href=\"https://github.com/babel/babel-preset-env/issues/21 &quot;TypeError: Cannot read property &amp;apos;loose&amp;apos; of undefined&quot;\">TypeError: Cannot read property 'loose' of undefined</a></li>\n</ul>","avatar":null}}}}
