    I am stuck on Installin necessary packages step

    I always got error and failed to fetch for all packages

    I managed to complete
    npm install ng2–dragula dragula —save
    npm install videogular2 –save
    when I changed —save to ——save

    But with all other cases- I always got failed to fetch.

    Please refer to screenshots:

    10 days had passed and still no answer



    Hi apologies for the late response ,

    @Pavel Safonov please try : cordova plugin add {plugin-name} –nofetch

    The cordova 7 uses the npm to install the plugins, and probably your npm is

    not globally installed, or misconfigured.

    the issue with the typescript error is fixed now in app update.Please download new ionic package from themeforest account .

    I have downloaded the latest version.

    and now i got error
    <span style=”color: #666666; font-family: -apple-system, Roboto, system-ui, ‘Segoe UI’, ‘Helvetica Neue’, sans-serif, ‘Apple Color Emoji’, ‘Segoe UI Emoji’, ‘Segoe UI Symbol’; font-size: 14px;”>Uncaught (in promise): TypeError: Cannot read property ‘length’ of null TypeError: Cannot read property ‘length’ of null at http://localhost:8100/build/main.js:1664:43 at t.invoke </span>

    And now i cannot log in with existing user id, the sign in button always open new browser for authentication.



    Please check the following code in your ionic app :



    locate the variable : this.settings

    and check the following lines :

    registration’:’app’,//’app’ or ‘site’ or false

    ‘login’:’simple’,//Select from ‘simple’ or ‘site’ or false


    make sure the registration is set to app and login is set to simple.
