创建 React App：安装时未创建 src 和公用文件夹 [重复]

Question

我在尝试创建 React 项目时使用 npx 或使用 yarn 总是冻结，

这是使用npx时的CMD部分：

D:\React_Redux_Course\React Projects>npx create-react-app my_app_test --use-npm
npx: installed 98 in 50.461s

我不知道问题到底出在哪里，可能还是缺少需要安装的软件包之类的？

对于这两种情况，我都没有找到 src 文件夹，并且按照我的解释总是卡住或冻结...

请给我一些建议...

编辑：

这是表示冻结的屏幕截图：

这是项目文件夹：

首先你应该删除旧版本的create-react-app cli

现在执行以下操作即可创建您的应用程序。

1. npm rm -g create-react-app
2. npm install -g create-react-app
3. npx create-react-app my-app

注意： 当使用正确的 create-react-app 版本时，你会看到一个额外的包cra-template

安装包。这可能需要几分钟。
