Windows10のWSLでJupyterLab+Javaを使う

Last updated at Posted at 2020-05-22

Windows10でJupyterLab+Javaを使いたかったので試してみた.
Jupyter Notebook上でJavaが動いたらなんか便利そうじゃない?

#インストール

Jupyterインストール

$ sudo pip install jupyterlab widgetsnbextension
$ jupyter lab --generate-config
$ cd .jupyter/
$ emacs jupyter_notebook_config.py

jupyter_notebook_config.py
# c.NotebookApp.use_redirect_file = True
c.NotebookApp.use_redirect_file = False

Jupyter用JavaKernelのインストール

$ git clone https://github.com/SpencerPark/IJava.git
$ cd IJava/
$ ./gradlew installKernel

#実行
$ jupyter lab
または,Windows上で以下のようなショートカットを作成

ショートカットを実行すると,ブラウザ上にJupyterLabが無事立ち上がる.
すごいすごい.

ブラウザ上にLauncherが立ち上がるので,Javaを選べばとりあえずは動く.
しかし,classpathの読み込み方がわからん.

ClassPathが設定できなきゃ何もできないなあ.
とりあえずClassPathの設定方法を調べよう.

ClassPathの設定の仕方はこちら.
