【问题描述】：

我正在处理一个项目，当我尝试运行 npm run build 时，我收到一条错误消息，提示“'CI 无法识别”。我一直在寻找答案，但我找不到任何东西。

这是我在 gitbash 中得到的：

 '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! barhop@0.1.0 prebuild: `CI=true react-scripts test --colors`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the barhop@0.1.0 prebuild script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

这是我的 package.json：

【问题讨论】：

这不是您在 Windows 中设置环境变量的方式。如果您需要跨平台运行脚本，请参见例如npmjs.com/package/cross-env

【参考方案1】：

如果您在 Windows 上运行，则需要更改预构建。

"prebuild": "set CI=true&react-scripts test --colors",
