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?

Answer 1

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.

Answer 2

I had the same problem, for me worked this:

bin/spring stop
bin/spring binstub --remove --all
bundle isntall && update

Answer 3

When I received that error I found that these three steps corrected the issue, albeit I am not sure how or why:

1. Uninstall the gem.
2. Install the gem, without a specific version to install the latest version.
3. Update my gem file to include this new version.

I am learning Ruby on Rails through a text, and it has me working with a specific version, but the entire thing did not work as it was supposed to, and I found that the above worked for me. I had to do it for four gems before things finally worked alright.

Answer 4

The main reason of your error may be that you forgot including your gem in your Gemfile . So ,

First of all check whether , the uglifier gem is present in your Gemfile.

After that , run bundle install again.

And then install devise .

I hope this helps.

Answer 5

我不确定这是不是问题，但是Devise 3.5.3的依赖是：railties <5，> = 3.2.6看起来你需要更新这个gem

Answer 6

我有同样的问题..通过安装nodejs修复它现在正在工作:)
