I created a new Rails project using
rails 3.1.0.rc4 on my local machine but when I try to start the server I get:
Note: This is not about Heroku.
To install nodejs on ubuntu, you can type the following command in the terminal:
sudo apt-get install nodejs
To install nodejs on systems using yum, type the following in the terminal:
yum -y install nodejs
Note from Michael 12/28/2011 - I have changed my accept from this (rubytheracer) to above (nodejs) as therubyracer has code size issues. Heroku now strongly discourage it. It will 'work' but may have size/performance issues.
If you add a runtime, such as therubyracer to your Gemfile and run bundle then try and start the server it should work.
Update, 12/12/2011: Some folks found issues with rubytheracer (I think it was mostly code size). They found execjs (or nodejs) worked just as well (if not better) and were much smaller.
n.b. Coffeescript became a standard for 3.1+
Add following gems in your gem file
gem 'therubyracer' gem 'execjs'
Install Node.js to fix it permanently for all projects.
sudo apt-get install nodejs does not work for me. In order to get it to work, I have to do the following:
sudo apt-get install python-software-properties sudo add-apt-repository ppa:chris-lea/node.js sudo apt-get update sudo apt-get install nodejs
Hope this will help someone having the same problem as me.
On the windows platform, I met that problem too The solution for me is just add
to the PATH
and restart the computer.
I had this issue on a Windows machine and installing node.js was the solution that finally worked for me. This came after trying multiple other routes including trying to get 'therubyracer' working. Though the github for node.js suggests that installation on windows is still unstable, the website at http://nodejs.org/ had a Windows installer which worked perfectly.
if you already install nodejs from source for example, and execjs isn't recognizing it you might want to try this tip: https://coderwall.com/p/hyjdlw
If all fails you can try
# aptitude install nodejs
as root. You can test your install with the following command:
# node -v
If you want to install NPM, please refer following link. Hope it helps.
On CentOS 6.5, the following worked for me:
sudo yum install -y nodejs
You can install NodeJS through the Node Version Manager or nvm:
$ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.0/install.sh | bash
Install Node through
nvm install 5.9.1
This will install version
5.9.1 of Node.
It turned out that we had a permissions issue. Run "ls -l" and see if the folder has the same owner and group as other working apps on the system. I had to run chown and chgrp on the folder (with the recursive switch) to fix it.
I hope you have pre-installed nodejs || nmv.
My solution does not require gem setup or installing 'node with
sudo apt" when you already have nvm.
All you need is to edit DesctopEntry of RubyMine. for that we will have those small steps:
/bin/bash -i -c. So your line should look like this
Exec=/bin/bash -i -c "/home/USERNAME/rubymine/RubyMine-2019.1.2/bin/rubymine.sh" %f
As a benefit all your environment variables are now available for RubyMine. So you feel no pain with additing them.
