I found packages unityeditor-cloud-hub-0.0.1.tgz and unity-editor-home-0.0.7.tgz in C:\Program Files\Unity\Editor\Data\Resources\Packages. Create folders node_modules\unityeditor-cloud-hub and node_modules\unity-editor-home in C:\Users\%user_name%\AppData\Roaming\Unity\Packages\. Extract dist and package.json from unityeditor-cloud-hub-0.0.1.tgz into unityeditor-cloud-hub, dist and package.json from unity-editor-home-0.0.7.tgz into unity-editor-home. It's work.
