'create-react-app' 未被识别为内部或外部命令

Question

我正在尝试在 windows pc 上使用 create-react-app 命令设置反应应用程序。我已经在我的 Mac 电脑上使用过它，而且效果很好。但是我遇到了一个问题。这是我在命令行上的步骤。我错过了什么吗？

 C:\Windows\system32>cd C:\Users\ugur\Desktop\deneme

C:\Users\ugur\Desktop\deneme>npm init

This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.

See 'npm help json' for definitive documentation on these fields
and exactly what they do.

Use 'npm install <pkg> --save' afterwards to install a package and
save it as a dependency in the package.json file.

Press ^C at any time to quit.
name: (deneme)
version: (1.0.0)
description:
entry point: (index.js)
test command:
git repository:
keywords:

About to write to C:\Users\ugur\Desktop\deneme\package.json:

{
   "name": "deneme",
   "version": "1.0.0",
   "description": "",
   "main": "index.js",
   "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
   },
   "author": "Ugur <[e-mail]> (http://www.abc.com.tr)",
   "license": "ISC"
}

Is this ok? (yes)

'create-react-app' is not recognized as an internal or external command, operable program or batch file.

npm配置路径也像

C:\Users\ugur\AppData\Roaming\npm\node_modules\create-react-app
