我用Jhipster创建了一个项目，该项目托管在AWS中。一切都很顺利，但我不得不格式化我的电脑并重新安装所有东西（相同的操作系统-Ubuntu 15.10）。然后，我安装了nodejs 5.10.0、npm 3.8.3和Jhipster 3.0。为了安装Jhipster，我遵循了这里描述的步骤，但使用sudo安装包：
sudo npm install -g yo
sudo npm install -g bower
sudo npm install -g grunt
sudo npm install -g generator-jhipster
（我的项目最初建立在Jhipster 2.23的基础上，使用grunt而不是gullow）
然后，我按照这里描述的步骤安装aws生成器（再次使用sudo）：$sudo npm install aws-sdk progress node-uuid
在我的系统中，全局节点模块可以在/usr/lib/node_modules找到，而不是安装在/usr/local/lib/node_modules。
但是，当我运行安装这些模块的命令时，我收到一条错误消息，generator-jhipster文件夹被删除（！）

我记得当我在以前的环境中安装它时，我在安装aws模块时也遇到了问题，但我通过使用某种技巧使它正常工作。这次我什么都想不出来。
我还尝试安装了过去的jhipster版本（2.23），尝试更改node_manager文件夹的权限并在没有sudo的情况下运行所有内容，尝试将其安装在主文件夹中，但没有成功。每当我在generator-jhipster文件夹下运行npm install aws-sdk progress node-uuid时，就会引发上一个错误，并删除该文件夹。
有什么想法吗？
编辑：根据@gaël-marziou的提示，我已经使用nvm重新安装了节点。我已经安装了nodev4.4.2，它是一个LTS版本。现在所有内容都安装在~/.nvm文件夹下。当我尝试在generator-jhipster文件夹下安装amy包时，我遇到了同样的问题：

谢谢，Jodevan。
很少有评论：
- 您不应该使用sudo运行npm（请参阅https://github.com/sindresorhus/guides/blob/master/npm-global-without-sudo.md)
- 您应该使用Node的LTS版本，正如我们在doc中建议的那样
- 同样，当你在Ubuntu上时，我建议你使用nvm来安装node，这样你就可以有几个版本
更重要的：JHipster不支持从2.x到3.0的项目升级。
您应该安装与您使用的版本相同的版本：npm install -g generator-jhipster@2.23.1
好吧，我不得不再次重新安装我的系统，这次一切都很好。我已经使用位于的ppa存储库安装了node v.4.4.4（LTS）https://nodejs.org/en/download/package-manager（我在之前的尝试中也这样做过）。我还使用上的说明安装了JHipster（2.23）及其依赖项http://jhipster.github.io/installation甚至与http://jhipster.github.io/aws.
现在一切都很顺利。转到图…
