packages/ide-python/node_modules/@atom-ide-community/nuclide-commons-ui/Checkbox.js:38 から開始します。ここでは Atom 1.58.0 および Electron 9.4.4 で activation に失敗するため、続いて AutoGenLaunchAttachUiComponent.js と AutoGenLaunchAttachProvider.js からの imports をたどります。報告された TypeError なしで Windows 上で package を activation できることを確認してください。issue では test file は指定されていません。
