JupyterLab: HTML Webpack Plugin: Type Error

Hi everyone, I have a problem when starting JupyterLab. When my browser opens it shows

Html Webpack Plugin:

TypeError: The ‘compilation’ argument must be an instance of Compilation

  • JavascriptModulesPlugin.js:119 getCompilationHooks

  • CommonJsChunkFormatPlugin.js:30

  • Hook.js:14 Hook.CALL_DELEGATE [as _call]

  • Compiler.js:987 Compiler.newCompilation

  • Compiler.js:1029

  • Hook.js:18 Hook.CALL_ASYNC_DELEGATE [as _callAsync]

  • Compiler.js:1024 Compiler.compile

  • Compiler.js:495 Compiler.runAsChild

Has anyone encountered a similar problem before?

We thought we had a fix in JupyterLab 3.0.6, but it seems people are still having issues. We’re discussing this over at Jupyter lab failed to build · Issue #9698 · jupyterlab/jupyterlab · GitHub. If JupyterLab 3.0.6 does not solve the issue for you, feel free to come by that issue and help us narrow down what might be causing this.
