### Commands

```
```

### Non-Core Packages

```
atom-python-test 1.0.1
autocomplete-python-jedi 1.10.3-0
ide-python 1.9.7
```

Windows 10 上の Atom 1.58.0 で ide-python 1.9.7 のアクティベーションを再現し、スタックトレースで参照されている欠落した node_modules/vscode-uri/lib/index.js を調査します。まず nuclideUri.js とパッケージ依存関係のメタデータから始めます。パッケージが欠落したモジュールのエラーなしでアクティベートすれば完了です。
