如何解决 react create app 'sh' 不是有效命令？

Question

npx create-react-app my-app

Creating a new React app in G:\project\my-app.

Installing packages. This might take a couple of minutes.
Installing react, react-dom, and react-scripts with cra-template...

'sh' is not recognized as an internal or external command,
operable program or batch file.

Aborting installation.
  yarnpkg add --exact react react-dom react-scripts cra-template --cwd G:\project\my-app has failed.

Deleting generated file... package.json
Deleting generated file... yarn.lock
Deleting my-app/ from G:\project
Done.

我已经尝试使用npm clear cache --force 清除 npm 缓存。同样的事情也会发生。
