每次我运行“npm run build”时，我都会收到此错误

Question

这是我运行“npm run build”时终端显示的错误

'CI' is not recognized as an internal or external command,
operable program or batch file.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! reminder@0.1.0 build: `CI= react-scripts build`
npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the reminder@0.1.0 build script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:

这是我的 package.json

而且我认为我由于“构建”而出错：“CI= react-scripts build”

所以请检查我的代码并回答它
