Ruby on Rails。 宝石错误找不到安装

Question

When I run rails server I get this error.

rescue in block (2 levels) in require': There was an error while trying to load the gem 'uglifier'

Then, I install it:

gem install uglifier
Successfully installed uglifier-2.7.2
...

But I still get the same error. What could it be? I'm using rvm and I'm new to Rails...

Answer 1

I think you need to install node js as there is a dependency on the run time, that helpfully does not show up.

Please find a link: Rake aborted, Error while trying to load the gem 'uglifier'

where they suggest apt-get install nodejs
