    After angular CLI upgrade webclipse server fails with: “Server failed to start”.
    Currently running webclips angular plugin version:
    After upgrading my projects to the following versions:
    Angular CLI: 6.1.2
    Node: 10.1.0
    OS: win32 x64
    Angular: 6.0.2

    When starting the server associated with the project I get the following error:
    TypeError: Class extends value undefined is not a constructor or null
    at patchServeCommand (C:\Users\williams\eclipse-workspace\device-gui\node_modules\angular-ide\addon\commands\serve.js:76:52)

    Please help me get my environment running on the latest angular cli.

    Sorry we missed this earlier. You may need to update the angular-ide module for full Angular 6 support. In a Terminal+ session for the project, enter the command:

    npm update angular-ide

    If that doesn’t fix the issue, please let us know the eclipse version, the full Webclipse version (from Preferences->Webclipse) and the npm version for the project (from the project Properties/CLI Tool Management page), to make sure we can try to replicate your environment. Also, if possible, attach your package.json file and the eclipse error log, which can be exported from the Error Log view.

    Sorry again for the late reply.

    Can you please let me know when you see this exactly? Is it when you execute the npm update, command or at some other time?

    Can you also please let me know your version of CodeMix as shown on the Preferences > CodeMix page.
