问题描述

当我尝试在应用程序中升级jhipster版本时，出现以下错误:

When I try to upgrade version of jhipster in my application I get following error:

lothrimond@lothrimond-K53SD:~/workspace/NScanner$ npm list generator-jhipster
n-scanner@0.0.0 /home/lothrimond/workspace/NScanner

推荐答案

我做了一个有效的"npm update -g generator-hipster".当您提到的错误发生时，我也在升级前的3.6.1上.

I did a "npm update -g generator-hipster" which worked. I too was on 3.6.1 prior to the upgrade when the error that you mentioned occurred.

https://jhipster.github.io/2016/09/16/jhipster-release-3.7.1.html 将此步骤称为手动升级.

https://jhipster.github.io/2016/09/16/jhipster-release-3.7.1.html refers to this step as manual upgrade.
