[英]Yarn errors when trying to create a React app
我嘗試使用以下命令創建一個React應用程序:
create-react-app eth-todo-list-react
這將產生以下錯誤:
'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,
operable program or batch file.
events.js:167
throw er; // Unhandled 'error' event

Error: spawn yarnpkg ENOENT

它應該說“成功”並初始化git倉庫。 但是我得到了上面的錯誤。 我嘗試了各種方法的故障排除,包括更改路徑和全局安裝yarn,但是當我這樣做之后,再次嘗試創建react app時,出現此錯誤:
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.
如果我刪除此文件並嘗試再次創建react應用,則會再次遇到第一個錯誤。
嘗試使用npx
命令,
npx create-react-app my-project
如果您使用npx
,則不需要像create-react-app
這樣的全局安裝軟件包。
全部告訴node -v
和npm -v
通過在控制台中鍵入create-react-app --version
來獲取您的create-react-app的create-react-app --version
。 這使用2.1.5版為我成功構建。 您可能需要更新您的create-react-app。 npm uninstall -g create-react-app
npm create-react-app eth-todo-list-react
應該使用最新版本的create-react-app。
