I think that line might blame to me with ES6 WeakMaps...

Looks like the following is working. How did you install jest? Using npm install jest -g?

node --harmony bin/jest.js -o

No tests to run!

I wonder if there's a way to specify node arguments this way

[ide]

Jest is globally installed. I guess what I want is for "jest" to automatically run node --harmony.

Can you try node-harmonize?

https://github.com/dcodeIO/node-harmonize

[sophiebits]

We changed the shebang line because travis's env doesn't like "/usr/bin/env node --harmony".

[ide]

What if we made "jest" a shell script that runs "usr/bin/env node --harmony jest.js $@"?

[sophiebits]

Shell scripts won't work on Windows (but otherwise that sounds like a reasonable idea…).

[jeffmo]

We might be able to work some crazy child_process hackery in the bin/jest.js file if we detect that --harmony wasn't used to execute the file...

[ide]

@jeffmo: I submitted PR #50 that uses @vjeux's suggestion of node-harmonize, which uses that trick. I don't know how to merge issues; sorry for opening up an extra one.
