我在 Amazon Linux AMI 上安装了 selenium。我尝试使用 python 来激活它。错误出现。我不知道应该是什么意思。chrome webdriver 可以在该环境中运行吗?
我的代码
from selenium import webdriver
driver = webdriver.Chrome("/home/ec2-user/dlfjj/bin/chromedriver")

在我的 Laravel 5.6 应用程序中,我尝试将一个$id变量从我的路由传递到我的数据表的每一列。
我的代码:
public function getVendorslistChange($id){
try {
return Datatables::of($this->purchaseRepository->getVendorListData(),$id)
->addColumn('action', function ($vendor,$id) {
return \Form::open(['method' => 'POST', 'action' => ['PurchaseController@postChangeVendor',$id], 'class' => 'form']) . '
<input type="hidden" name="id" value="' . $vendor->id . '" />
<input type="submit" name="submit" value="Choose" class="btn center-block" />
' . \Form::close();
})
->make(true);
} catch (\Exception $e) {
return $this->redirectWithErrors($e);
}
}

这部分$this->purchaseRepository->getVendorListData()将返回以下内容:
public function getVendorListData(){
$this->vendors = Vendor::Select(
array(
'vendors.id',
'vendors.company_name'
))
->where('vendors.company_id',return_company_id())
->where('status','Active')->get()
;
return $this->vendors;
