我正在尝试使用 npx create-react-app first-react-app 创建 React 应用。
当它开始创建应用程序时，我每次都会收到以下警告。最后是创建一个应用程序。但这是什么原因，我该如何永久解决这个问题？
这里是所有日志：

您可以忽略此警告。查看有关此警告的更多信息 here
<块引用>这是意料之中的，可以忽略。我们还不能忽略可选包（在本例中为 canvas）
要禁用此消息，请尝试使用：
yarn config set ignore-engines true
或者尝试使用 --use-npm --no-optional 标志
npx create-react-app first-react-app --use-npm --no-optional
