<p>- Change: CopyPlugin({ patterns, options })</p>
<h2>Solution</h2>
<pre class="language-javascript"><code>// 기존: new CopyPlugin([ { from: "./node_modules/axios/dist/axios.min.js", to: "./axios.min.js", // 목적지 파일에 들어간다 }, ]), // 변경 (이렇게 변경하세요) new CopyPlugin({ patterns: [ // patterns 키를 추가합니다. { from: "./node_modules/axios/dist/axios.min.js", to: "./axios.min.js", // 목적지 파일에 들어간다 }, ] }),</code></pre>
