@lckr/jupyterlab_variableinspector のインストール

Question

versions

jupyter-core 4.7.1
jupyter lab 3.0.16
conda version : 4.10.3
node 14.17.3
npm 6.14.13

jupyter labを新しく使用したいと考えjupyter notebookから移行しようとしている者です。
他の拡張機能は問題なく使えております。

便利な@lckr/jupyterlab_variableinspectorをインストールしようと思うのですが

 jupyter labextension install @lckr/jupyterlab_variableinspector

を実行すると

(base) matsusesatoshi@matsusesatoshinoMacBook-puro ~ % jupyter labextension install @lckr/jupyterlab_variableinspector
Building jupyterlab assets (production, minimized)
An error occured.
RuntimeError: JupyterLab failed to build
See the log file for details:  /var/folders/ll/cdp3xh194t7_9c631lm07yx00000gn/T/jupyterlab-debug-0an40nwu.log

といったエラーではじかれてしまします。

試したことは
node,npmの再インストール
jupyter, jupyter-core の再インストール
build_config.jsonの削除及び再インストール

インターネットで検索し、できそうなことは試したのですが何がいけないのでしょうか...
ご回答あるいは、ほかの似たような拡張機能を知ってらっしゃったら教えていただけると嬉しいです。

logの内容でエラーを吐いている内容は下に記します。

私もインストールできずに困っていたのですが、下記のようにバージョン3.0.7を指定してやったところインストールできました。

jupyter labextension install @lckr/jupyterlab_variableinspector@3.0.7

バージョン指定せずに実行すると、バージョン3.0.9 をインストールしようとするのですが、ダウンロードされるファイルの中身が足りていないように見えます。
githubの公式ページを見ても、3.0.9というバージョンが正式にリリースされているものなのかが、よくわからないです。
