Cloud9's git repository and instructions have changed since the other answer was posted. See https://github.com/c9/core/ for more information. The following instructions seem to work for me on a vanilla Ubuntu 14.04.
Install Git if you haven't already:
sudo apt-get update && apt-get install build-essential sudo apt-get install git
Install node.js if you don't already have a recent version installed:
# Install node.js wget -O ~/node-v0.10.33-linux-x64.tar.gz http://nodejs.org/dist/v0.10.33/node-v0.10.33-linux-x64.tar.gz tar -zxf ~/node-v0.10.33-linux-x64.tar.gz rm ~/node-v0.10.33-linux-x64.tar.gz echo 'export PATH=$PATH:~/node-v0.10.33-linux-x64/bin' >> ~/.bashrc source ~/.bashrc
Download and setup Cloud9:
# Setup and start Cloud9 server # (You can get a zip file instead of using git) git clone https://github.com/c9/core.git c9sdk c9sdk/scripts/install-sdk.sh
After the server starts successfully, you can stop it with
Ctrl-C
. Then you can start it with a different workspace:node c9sdk/server.js -w ~/my_workspace/
Visit http://localhost:8181 to see the Cloud9 IDE in your browser.
If you don't like the self-hosted Cloud9 web-IDE, you can try Orion, Codiad, or Codebox.
