Node.js 模块jenkins用户ELIFECYCLE的npm安装失败

我们有一个运行Jenkins的EC2 Ubuntu box，它构建并测试一个节点应用程序。詹金斯做的部分工作是下载依赖项。其中一个依赖项hashring在安装时出现ELIFECYCLE错误。但是，该错误仅在使用jenkins用户安装时发生。我可以用ubuntu用户安装sudo，但我似乎不能用jenkins用户安装这个软件包。jenkins用户可以很好地安装所有其他软件包。下面是一个为ubuntu而不是为jenkins安装hashring的示例，然后jenkins成功安装了express

有什么想法吗？我觉得我什么都读过，什么都试过了。我已经完全卸载并重新安装了node、npm和node gyp，并根据这个问题尝试使用每个版本的不同版本组合，但似乎没有效果

事实证明，我们必须使用python路径为npm添加一个配置

来自jenkins用户：

npm配置集python/usr/bin/python
