Error: Cannot declare trait Khill\Lavacharts\Support\Traits\HasOptionsTrait, because the name is already in use

What Version?

3.1.11

Issue

Getting following error in Symfony 3.4 with PHP 7.1:

Error: Cannot declare trait Khill\Lavacharts\Support\Traits\HasOptionsTrait, because the name is already in use

Controller Code (chart creation code)

        $lava = $this->get('lavacharts');
        $lava->setLocale('pt_BR');
        $table = $lava->DataTable();

        $table->addStringColumn('Ano')
            ->addNumberColumn('Filmes com profissionais mulheres')
            ->addNumberColumn('Total de filmes')
        ;

        foreach ($qb->getQuery()->getResult() as $ano) {
            $table->addRow([
                $ano->getNome(), $ano->getNumFilmeProfissional(), $ano->getTotalFilme()
            ]);
        }

        $chart = $lava->AreaChart('AnoGraficoIndex', $table, $this->chartDefaultOptions());

View Code

<div id="ano_list_chart" class="grafico"></div>
{{ areachart('AnoGraficoIndex', 'ano_list_chart')|raw }}

Does Symfony already have that trait?

[glauberm]

@kevinkhill No. Neither Symfony nor the project dependencies.

Same problem for me
Any help would be appreciated

Version 3.1
Symfony 4
PHP 7.1.3

[glauberm]

@OCoulonAckwa IIRC, deleting the vendor folder and running a fresh composer install fixed the problem.

[JWPapi]

Unfortunately not for me.

for me the full line is:

!! PHP Fatal error: Cannot declare trait Khill\Lavacharts\Support\Traits\HasOptionsTrait, because the name is already in use in /var/www/igStoryViewer/vendor/khill/lavacharts/src/Support/Traits/HasOptionsTrait.php on line 22

I wonder why it tries to get the same HasOptionsTrait from different sources
