**Describe the bug** When running `yarn install`, Yarn throws an invariant violation and fails to install. I traced this down to `packages/pagebuilder/package.json` which defines: ``` "devDependencies": { ... "react-tabs": "~3.0.0" }, "peerDependencies": { ... "react-tabs": "~3.1.0" } ``` This breaks Yarn workspaces because it can't resolve to a single version. **Expected behavior** Yarn can install. **Possible solutions** I will submit a PR. There isn't a breaking change between `react-tabs` 3.0.0 and 3.1.0. It only added LTR locale support. The Pagebuilder package should define both dependencies with 3.1.0, so Yarn works. **Please let us know what packages this bug is in regards to:** - [ ] `venia-concept` - [ ] `venia-ui` - [x] `pagebuilder` - [ ] `pwa-buildpack` - [ ] `peregrine` - [ ] `pwa-devdocs` - [ ] `upward-js` - [ ] `upward-spec` - [ ] `create-pwa`
