Ich verwende Ubuntu 16.04, das von Virtual Box im Win7-System erstellt wurde, und habe bei der Verwendung desnpm install bcrypt安装bcryptPlug-Ins den folgenden Fehler festgestellt:

Das Ubuntu-System, das ich direkt zuvor verwendet habe, hat die gleiche Methode verwendet und der oben genannte Fehler ist nicht aufgetreten. Vielen Dank! !
