I am not able to find 'script' package in atom text editor

I recently installed atom text editor and start using it. I want to use it mainly to run Python codes. for that, I am trying to install a few packages like 'script'. I am not able to find this package.
Have you tried downloading it directly from the site and opening it with atom https://atom.io/packages/script
Make "Atom" as Default atom:// Protocol Handler by clicking on the "Settings" and "URI Handling" then go to the link atom.io/packages/script, you will find the package and install it

run the command that corresponds to your operating system

when i run [enter image description here],it show bash: workflows-java/build/nodes/run-nodes : No such file or directory.
Thanks.

The docs is currently being updated to accommodate the code changes in the cordapp-example repo.
The correct instruction for Linux and MacOs is:
./gradlew deployNodes
./build/nodes/runnodes

Installing iPython Notebook - opening a $HOME file from editor

I am attempting to install ipython notebook based on some instructions. However, while I tried to execute this 'In your favorite editor, open the file $HOME/.ipython/profile_default/ipython_notebook_config.py', I can't really open a file from TextWrangler. I am not familiar with this. Could anyone help me out there? Thank you very much!!
maybe it's not there? you can create it first, in Mac's terminal
touch $HOME/.ipython/profile_default/ipython_notebook_config.py
and then open it in TextWranggler
open -a /Applications/TextWrangler.app $HOME/.ipython/profile_default/ipython_notebook_config.py
