没有这样的元素：无法在硒中找到元素

Question

我正在尝试打开youtube链接，然后单击频道，但可惜它找不到频道链接。以下链接显示带有红色箭头的目标链接。

因此，这是我的代码，有关更多详细信息，您可以检查此repo：

    Driver driver = new Driver();
    driver.laodPage("https://www.youtube.com/watch?v=tFPzE4Twj4k");
    driver.getCurrentURL();
  //  driver.getElementById("img").click(); 
    driver.click("//*[@id=\"img\"]"); //Click on video channel 
    driver.getCurrentURL();

但它抱怨：

NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"//*[@id="img"]"}

我在chrome控制台上检查了xpath，它给了我21个元素的数组，所以我想也许是因为它。然后，我尝试将其更改为"//*[@id=\"img\"][1]"，它给了我一个元素，但仍然有问题。

<ListBox ItemsSource="{Binding WeeklyWeather}"
         SelectedItem="{Binding SelectedDailyWeather, Mode=TwoWay}">

    //Use ItemTemplate to set how item looks "inside"
    //I'll leave design details for you
    <ListBox.ItemTemplate>
        <DataTemplate>
            <StackPanel>
                <TextBlock Text="{Binding Day}"/>
                <Image Source={Binding WheatherPicturePath}/>
                <TextBlock Text="{Binding Temperature}"/>
                <TextBlock Text="{Binding Description}"/>
            </StackPanel>
        </DataTemplate>
    </ListBox.ItemTemplate>

    //ItemsPanel defines container for items. It can be StackPanel, Wrapanel, Grid, etc
    <ListBox.ItemsPanel>
        <ItemsPanelTemplate>

        </ItemsPanelTemplate>

                        //You use this place to design how container normally looks like
                        <Border Background="White">
                            //DataTemplate defined above is placed in ContentPresenter

            </Setter>
            <Style.Triggers>
                //Here we catch "IsSelected" event and re-design our template to visually reflect "selected"

                                <Border Background="Gray">
                                    <ContentPresenter />
                                </Border>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                </Trigger>
            </Style.Triggers>
        </Style>
    </ListBox.ItemContainerStyle>

</ListBox>
