Error installing extension

edited March 2020 in Developers

I asked this question in another thread, but it might be more appropriate to pose it in a thread by itself.

I tried to install the development version of the outcomeui-extension (in order to get correct duration times), but I get the error below

composer require oat-sa/extension-tao-outcomeui
sudo php tao/scripts/installExtension oat-sa/extension-tao-outcomeui

And then I get the error:

Fatal error: Uncaught An error occured during the installation of extension 'oat-sa/extension-tao-outcomeui'.
thrown in /var/www/tao33/tao/helpers/InstallHelper.php on line 46

I am using PHP and TAO 3.3.0-RC02.
I also tried to install npm, but I get the same error.

Any idea what I did wrong?


  • The right way to install an extension would be this:

    sudo php tao/scripts/installExtension taoOutcomeUi

    You have to use the name of the extension which can be found in manifest.php of each extension.

    I hope this helps.

  • Correction, installExtension should be installExtension.php
