My observations:

• You install ‘webdriverIO’ with yarn and the yarn.lock is updated/created.
• Then you run: ‘./node_modules/.bin/wdio config’ and select config options
• I think the issue is that the WDIO configuration helper uses npm to install selected dependencies (e.g spec reporter, jasmine etc),
• hence creating a package-lock.json file. Causing this issue because webdriverio in yarn.lock and not in the package-lock.json with selected reporters, frameworks etc.

Walk-around fix:

1. Install ‘webdriverio’ with: yarn add -D webdriverio
2. Run wdio config helper: ./node_modules/.bin/wdio config ![screen shot 2018-10-17 at 5 00 21 pm](https://user-images.githubusercontent.com/23148951/47121128-a9914a80-d22e-11e8-8b46-401aad9d3e18.png)
3. Select desired options but don’t the have helper install any of them for you, by responding with ‘no’ (e.g Shall I install the framework adapter for you? No).
4. Configuration file was created successfully!
5. Manually install the required services, frameworks and/or reporters with yarn either by: a. Adding them to your package.json file and running yarn install b. Yarn add each one of them
