They can almost certainly migrate to the native JavaScript promise now. Thank you literally everyone for joining me in this bet against the odds. Be excellent to each other.

A template was not provided. This is likely because you're using an outdated version of create-react-app.
Please note that global installs of create-react-app are no longer supported.
You can fix this by running npm uninstall -g create-react-app or yarn global remove create-react-app before using create-react-app again.

解决方案 #

1. 彻底清除全局残留的create-react-app #

• 检查全局是否仍有残留：

  npm list -g create-react-app
  

• 若存在残留，再次卸载：

  npm uninstall -g create-react-app
  # 或用yarn
  yarn global remove create-react-app
  

• 清理npm缓存：

  npm cache clean --force
  

2. 使用npx直接调用最新版create-react-app #

官方已废弃全局安装方式，必须通过npx调用最新版本创建项目：

npx create-react-app@latest 你的项目名
# 或用yarn
yarn create react-app 你的项目名

3. 手动指定模板（若仍提示模板缺失） #

如果上述命令仍报错，手动指定官方默认模板：

npx create-react-app@latest 你的项目名 --template cra-template
# TypeScript项目用这个
npx create-react-app@latest 你的项目名 --template typescript

4. 处理依赖弃用与漏洞 #

项目创建完成后，进入项目目录：

• 升级所有依赖到最新版：

  npm update
  

• 修复漏洞：

  npm audit fix
  

• 针对特定弃用包，手动替换为推荐版本（比如将babel的proposal系列插件换成transform系列，升级rimraf到v4+等）。
