当我导入excel文件时，方法块不存在

Question

我试图从excel导入100k数据到数据库，我有超时问题，所以我使用了块方法，但它说“块方法不存在”。我该如何解决这个问题？

Excel::filter('chunk')->load($request->file('excelFile')->chunk(900, 
function ($reader) use ($electionId, &$voterCount, &$lastVoter,&$rowError) 
{
     foreach ($reader->toArray()[0] as $row) {
     $voter                  = new Voter();
     $voter->electionId      = $electionId;
     $voter->voterNumber     = $row['voter_id'];
     $voter->name            = $row['name'];
     $voter->password        = $row['password'] === 
     null || $row['password'] == '' ? rand(1,100000) : $row['password'];
     $voter->emailAddress    = $row['email'];
     $voter->mobileNumber    = $row['mobile_number'];



     }
     }));
