＆＃34; bnr未被识别为内部命令＆＃34;同时开发ionic2-cordova app

Question

这是我在尝试构建android时遇到的错误。有人可以帮忙吗？

'bnr' is not recognized as an internal or external command, operable program or batch file.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! ionic2-taxi-app@0.1.0 dev: `bnr dev`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the ionic2-taxi-app@0.1.0 dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

在我正在进行的项目中，有时会出现该错误。通常当某些命令执行失败时，但我不确切知道原因。无论如何，似乎执行npm install再次解决了问题。
