我尝试使用以下命令创建一个 react 应用程序:
create-react-app eth-todo-list-react
这会产生以下错误:
'yarnpkg' is not recognized as an internal or external command,
operable program or batch file.
Installing packages. This might take a couple of minutes.
Installing react, react-dom, and react-scripts...
'yarnpkg' is not recognized as an internal or external command,

它应该显示“成功”并初始化 git 存储库。但我得到了上面的错误。我尝试过各种方法进行故障排除，包括更改路径和全局安装 yarn ，但是当我这样做然后再次重新尝试创建 react 应用程序时，我收到此错误:
The directory eth-todo-list-react contains files that could conflict:
package.json
yarn.lock
Either try using a new directory name, or remove the files listed above.
如果我删除此文件并尝试再次创建 React 应用程序，我会再次收到第一个错误。
最佳答案
尝试使用npx命令，
npx create-react-app my-project
如果您使用npx，则不需要像create-react-app那样全局安装软件包。
全部告诉node -v和npm -v
