我很难运行反应命令

问题描述

我刚刚更新了我的 npm 并删除了一些无用的包，但由于某种原因，我在尝试运行此命令时仍然遇到一些奇怪的问题

kalebamarante$ npm init create-react-app kalebcryptoexchange-app
npm ERR! code E404
npm ERR! 404 Not Found - GET https://registry.npmjs.org/create-create-react-app - Not found

You are running `create-react-app` 4.0.1,which is behind the latest release (4.0.3).

We no longer support global installation of Create React App.

Please remove any global installs with one of the following commands:
- npm uninstall -g create-react-app
- yarn global remove create-react-app

解决方法

你应该试试 npx 而不是 npm init。 npx create-react-app kalebcryptoexchange-app。

,

你应该使用 npx 而不是 npm。

npx create-react-app your-app

现在为什么会这样？

当您使用 npm 命令时，它会为您获取节点包。即您可能已经使用 npm 全局安装了名为“create-react-app”的包。现在要执行该包，您必须使用 npx 命令。

您的错误日志显示了这一行，

npm ERR! 404  'create-create-react-app@latest' is not in the npm registry.

因为您正在尝试获取一个包，而不是使用 create-react-app 创建它。

简而言之，npm 下载包，npx 执行包。
