reactjs - create-react-app 只创建 node_modules、package 和 package-lock

Question

在我的终端中:

D:\>npx create-react-app myapp                                                                                      
npx: installed 98 in 21.893s                                                                                        

Creating a new React app in D:\myapp.                                                                               

Installing packages. This might take a couple of minutes.

安装后我的 package.json:

{
  "name": "client",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "cra-template": "1.0.3",
    "react": "16.13.1",
    "react-dom": "16.13.1",
    "react-scripts": "3.4.1"
  }
}

然后它永远卡在那里。
我尝试安装全局 create-react-app，更新最新的 npm，删除 Appdata 中的 npm 仍然无效，需要帮助

Answer 1

从 create-react-app 3.3.0 开始，不再推荐使用 CRA 的全局安装。
这是 github 上提出的问题，但后来在此解决方案后关闭

npm rm -g create-react-app
npm install create-react-app
npx create-react-app my-app

它所做的只是:

Command 1: deletes the create-react-app installed globally

Command 2: Installs create-react-app locally

Command 3: Creates a new react-app with all the expected file structure.

试试这个，如果那也不起作用，请检查以下说明...
仅适用于 Windows 用户
对于很多 Windows 用户来说，这是一个问题。

Even after trying all the troubleshooting steps did not resolve the issue.

Finally it was found that they had some missing paths in their environment variables.

注意:我们这里不是在讨论设置 npm 路径
在将这些添加到 env 变量之前，它没有得到解决。

C:\Windows;C:\Windows\system32;C:\Windows\System32\Wbem

它区分大小写，完全按照它提到的方式粘贴
但是，随着时间的推移，这些错误变得越来越少，不确定这是否会有所帮助。
