npm config set registry "https://registry.npmjs.com/"

Replace the registry url with the above urls check which one works for you.

After That:

    "npm cache clean --force" didn't work for me but removing package-lock.json worked. https://github.com/vuejs-templates/webpack/issues/990#issuecomment-395750082

    Removing package-lock.json worked for me.

    Add Powershell script or Linux script as below,

    Powershell:

    Remove-Item package-lock.json  -Force

    Linux:

    rm -rf package-lock.json

    Path In Azure Devops:

    $(System.DefaultWorkingDirectory)\appName\appName\ClientApp\node_modules'

    Note - appName is an example you can add a path as per your source code.
