node.js - npm 安装 Reactjs 应用程序 npm 错误!代码 E404

Question

我是reactjs新手，我正在尝试创建一个reactjs应用程序，我按照react web上的步骤操作，但它显示错误。我的node版本是v8.11.1.npx版本是9.7.1。

顺便说一句，我可以使用 npx create-react-app 创建应用程序，但是当使用 npm 失败时。

MacBook-teddy$ npm install -g create-react-app 
create-react-app amber_Web 
npm ERR! code E404
npm ERR! 404 Not Found: amber_Web@latest

看起来您在安装时尝试运行 create-react-app。

运行npm install -g create-react-app，尽管它应该已经安装了。

然后运行create-react-app amber-web

编辑:

出现此错误的原因是因为您输入了 npm install -g create-react-app
create-react-app amber_Web 全部在一个命令中，告诉 npm 安装 create-react-app 包两次和 amber_Web 包，但该包不存在，因此出现 404 错误。 * 名称不能再包含大写字母
