Fatal error: Class 'League\Csv\Reader' in not found

[lucasound]

Hi,

in console, i have this error:

Fatal error: Class 'League\Csv\Reader' in not found in /var/www/vhosts/sito.com/httpdocs/app/code/FireGento/FastSimpleImportDemo/Console/Command/Product/ImportCsv.php on line 75

what is the problem?

The missing class is not a part of FastSimpleImport, an external library. If you install FastSimpleImport with composer (which is recommended), the library will be installed automatically. You can find installation instructions for League_Csv on https://github.com/thephpleague/csv#install. If you can't use composer, you can copy the content of https://github.com/thephpleague/csv/tree/master/src to the lib/internal folder of your Magento installation.
