运行devise时，devise给出错误：在rails应用程序中安装 [英] Devise gives error while running devise:install in rails application

问题描述

我正在使用ruby 2.2.3和rails 4.2.5。我无法在我的项目上运行rails generate devise：install。捆绑器抛出错误。错误类似于以下

当我用rails生成devise：install时，我一直收到错误消息。我尝试卸载devise并重新安装。我什至尝试卸载uglifier并重新安装。我不明白是什么原因引起的？是捆扎机吗？

I keep getting the error when i do rails generate devise:install. I tried uninstalling devise and reinstalling it. I even tried uninstalling uglifier and reinstalling. I am not being able to understand what is causing the issue? is it the bundler?

推荐答案

已解决。问题是nodejs。我当时使用nvm来管理我的nodejs，我切换到了系统范围内的sudo apt-get install nodejs，并且切换了nvm以使用系统版本并开始工作。

It has been resolved. The problem was nodejs. I was using nvm to manage my nodejs, i switched to system wide sudo apt-get install nodejs and switched nvm to use the system version and devise started working.
