c# - 找不到 MVVM EventToCommand

Question

大家好，我正在尝试在列表框的项目中实现点击效果，但我一直收到此错误:

未找到类型“cmd:EventToCommand”。确认您没有缺少程序集引用，并且所有引用的程序集都已构建。

<catel:UserControl
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         xmlns:catel="http://catel.codeplex.com"
         xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
         xmlns:cmd="http://www.galasoft.ch/mvvmlight"
         mc:Ignorable="d" 
         d:DesignHeight="300" d:DesignWidth="300">

以及我尝试实现点击方法的代码:

<Grid>
    <ItemsControl ItemsSource="{Binding Source={StaticResource cvsRoutes}}">
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <Expander Header="{Binding Name}" MinHeight="50">
                    <ListBox>
                        <i:Interaction.Triggers>
                            <i:EventTrigger EventName="PreviewMouseLeftButtonDown">
                                <cmd:EventToCommand Command="{Binding PreviewMouseLeftButtonDownCommand}" PassEventArgsToCommand="True"/>
                            </i:EventTrigger>
                        </i:Interaction.Triggers>
                        <TextBlock Text="Something" >
                        <i:Interaction.Triggers>
                            <i:EventTrigger EventName="KeyUp">
                                <cmd:EventToCommand Command="{Binding KeyUpCommand}" PassEventArgsToCommand="True"/>
                            </i:EventTrigger>
                        </i:Interaction.Triggers>
                        </TextBlock>
                        <TextBlock Text="Something" />
                        <TextBlock Text="Something" />
                        <TextBlock Text="Something" />
                        <TextBlock Text="Something" />
                    </ListBox>
                </Expander>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
</Grid>

你能告诉我问题是什么吗？我该如何解决？

有一个很好的列表，列出了 Catel 中可用的所有行为和触发器以及如何使用它们:

它还包括 EventToCommand:
