The bug report and possible fixes can be found here: ionic-team/stencil#1491

Stencil does not work with symlinks, I suspect that the problem is with rollup, it might require extra configurations based on this issue #447.

The issue happens when I try to use lerna to link between packages:

I used npm init stencil and picked the components starter template for the stencil part.

root
    /packages
        /x-alpha (exports a string)
        /x-beta (imports x-alpha successfully)
        /x-stencil (from stencil-cli fails to import x-alpha)

The same issue also happens when trying to manually use npm link or yarn workspaces.

1. run npm install to install lerna in the root directory.
2. run npm run bootstrap to let lerna bootstrap the local dependencies.
3. go to packages/x-beta and run npm start, you should see that the symlink was connected, it will print: successfully imported alpha: alpha.
4. go to packages/x-stencil, install dependencies and call npm start, stencil fails to resolve symlink dependencies. stencil gives this error in the browser console:

ReferenceError: module is not defined
