【问题描述】:
我尝试使用以下命令创建一个反应应用程序:
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,
operable program or batch file.
events.js:167
throw er; // Unhandled 'error' event

Error: spawn yarnpkg ENOENT

它应该说“成功”并初始化一个 git 存储库。但我得到了上面的错误。我已尝试对各种方法进行故障排除,包括更改路径和全局安装纱线,但是当我这样做然后重新尝试再次创建反应应用程序时,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。
【问题讨论】:
-
修改PATH后,当前打开的cmd窗口不受影响,需要关闭再重新打开。
-
关闭和打开 cmd 没有区别。我总是遇到同样的错误。
-
尝试先使用“npm install yarn -g”安装yarn
-
已经尝试全局安装yarn,我得到同样的错误。
