当我在laravel应用程序中访问视图时,为什么总是每1分钟显示该错误:
file_put_contents(/home/vagrant/Code/myproject/storage/framework/cache/data/db/59/db59a863cb50aaccca0c973c049bd67971a7e3ae): failed to open stream: Permission denied
吗?
当我运行chmod -R 777 storage/
时,它可以工作,但随后每隔1分钟就会更改一次权限。
即使我这样做:
php artisan config:cache
php artisan cache:clear
php artisan view:clear
php artisan clear-compiled
不适用于我。
我正在使用:
请帮助。谢谢您的回答。

使用prices = prices.set_index('datetime').asfreq('1Min')
print(prices)
open high low close

我尝试了以下方法,并且对我有用:
public class MyViewCell : ViewCell
{
private Color BackgroundColor
{
get => CellGloss.GetBackgroundColor(this);
set => CellGloss.SetBackgroundColor(this, value);
}
public Color EvenColor { get; set; }
public Color UnevenColor { get; set; }
protected override void OnAppearing()
{
base.OnAppearing();
if (!(Parent is ListView listView))
throw new Exception(
$"The Binding Context is not {typeof(ListView)}. This component works only with {typeof(ListView)}.");
int index;
if (listView.IsGroupingEnabled)
{
index = listView.TemplatedItems.GetGroupAndIndexOfItem(BindingContext).Item2;
}
else
{
index = listView.TemplatedItems.IndexOf(this);
}
if (index != -1)
BackgroundColor = index % 2 == 0 ? EvenColor : UnevenColor;
}
}
更改以下参数:
<components:MyViewCell EvenColor="White" UnevenColor="#eeeeee">
