创建React App：src和公用文件夹未在安装时创建

Question

使用npx或使用yarn总是冻结时，我试图创建一个React项目，

这是使用CMD时的npx部分：

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

Creating a new React app in D:\React_Redux_Course\React Projects\my_app_test.

，并在使用yarn命令以及以下cmd时冻结：

我不知道问题出在哪里，可能仍然缺少需要安装的软件包或什么东西？

对于这两个我都没有找到src文件夹，并且总是卡住或冻结，正如我所解释的...

请给我一些建议...

这是冻结的屏幕截图：

这是项目文件夹：

首先，您应删除旧版本的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： 使用正确的create-react-app版本时，您会看到一个附加软件包cra-template
