We should generate the `lerna.js` just as we did in Theia

[kittaakos]

Otherwise, running yarn will hit a deadlock on Windows due to the parallel execution.

Update: copy the lerna.js from here into the root of your extension (where you can find the actual extension with the example apps) and replace lerna with node lerna.js in your npm scripts.

Update2: make sure the lernaPath points into lerna inside the node_modules/.bin

I wonder: can we make it as a part of Theia cil tooling instead of copying scripts?

instead of copying scripts?

I needed a working solution.
