In order to properly run and test Blockly's devtools, install node.js and NW.js on your computer. Instructions for installation can be found on the linked sites.

In your devtools directory run

npm install

Find the relative path to nwjs/nw that you installed onto your computer. Run the following command from the devtools repo's directory.

nwjs/nw .

Doing so will run devtools as an NW.js application on your computer.

If you get an error about "closure" upon loading the app, it probably means the blockly-devtools/closure-library/ directory has not been set up. Try running:

git submodule update --init --recursive

Alternatively, install the closure-library into that directory. If you are working with the web library, you may prefer to share a local copy via a symlink (i.e., ln -s path/to/closure-library).

We are currently working on removing this dependency, but this will fix the issue until then.
